But compared to others they come out significantly better in terms of secondary impacts such as water use, greenhouse gas emissions, pollution and social disturbance.

1. The sun is everlasting
The sun has been shining long before civilization as we know it began. People have become dependent on solar energy for light and heat as it is most reliable. As this energy is renewed daily with never-ending sunshine, solar photovoltaic (PV) capacity has grown fastest among all renewable energy in recent years.

Harnessing the sun’s energy poses no threat to health and the environment – and it is definitely . Fossil fuels such as coal, oil and gas, are highly polluting as they release chemicals and toxic elements into the atmosphere, land or sea when they are mined, drilled or transported. Oil spills from Exxon Valdez tanker and BP’s Deepwater Horizon oil rig are just two of the many environmental disasters that have hit the headlines. These oil spillages reduced wildlife populations and cost fishery and tourism companies huge losses for years.

Solar PV cells are made from crystalline silicon found most commonly in silica sand. Although certain chemicals are used to clean the semiconductor surface of the PVs during manufacture, leading solar manufacturers follow strict environmental laws and observe proper industrial waste disposal, ensuring no ongoing harm to both workers and environmental ecology.

PVs also minimise land impact; small scale PV panels are located on rooftops while large ones such as utility-scale solar systems are sited typically on low grade land or disused locations such as brownfield sites and abandoned mining land.

3. Climate change mitigation
Conventional energy sources are known to release massive amounts of carbon dioxide and greenhouse gases, which trap heat within the earth’s atmosphere and raise surface temperatures. Since the start of the industrial revolution, these have contributed towards unprecedented climate change. Results of this increase include extreme weather conditions worldwide, such as dry spells, droughts, wild fires, storms, hurricanes and flooding.

In contrast, the use of solar energy through PV panels to provide electricity does not emit any harmful gases as the fuel source that drives this energy is the sun. There are minor emissions in other stages of the solar lifecycle during manufacturing and material transportation.

However, most estimates of life-cycle emissions for PV systems are between 0.07 and 0.18 pounds (lbs) of carbon dioxide equivalent per kilowatt-hour (CO2E/kWh). Estimates for concentrating solar power (for heat) range from 0.08 to 0.2 lbs of CO2E/kWh. Both of these are still far less than the lifecycle emission rates for natural gas (0.6-2 lbs of CO2E/kWh) and coal (1.4-3.6 lbs of CO2E/kWh).

Charging electric vehicles using PV cells would be almost ideal to cap pollution. Some PV panels are in fact manufactured using solar power and efficient energy systems, reducing even further any carbon emissions during the manufacture stage.

was the first company in the global PV sector to obtain Product Carbon Footprint Verification from TÜV Rheinland, a leading assessor of the product life-cycles. As part of this, the company boasts 39 Gigawatthours (Gwh) of clean energy powering its headquarters and production sites yearly.

77334.com
Water, a basic human need, is a precious resource that has been found lacking in many dry and troubled areas. The Sustainable Goals report says poor water supplies affect more than 40% of the world’s population. As many as 663 million people do not have access to clean drinking water.

Agriculture, according to , is the biggest water user worldwide. Biofuels, claimed by some as a clean fuel source, ironically consume significant amounts of water during irrigation and feedstock processing, and in some cases result in human conflicts over land rights and water access.

Hydropower dams – another claimed “clean” source of electricity are widely used as renewable energy sources. But often, homes and villages are destroyed or relocated to make way for dam projects. River systems are usually altered, which affects wildlife habitats and freshwater ecosystems.

Compared to hydropower and biofuels, solar technology creates less disruption to people and wildlife. Although water is used in the manufacture operations of PV cells, responsible solar manufacturers such as Yingli take water consumption and waterways pollution seriously. They monitor manufacturing and distribution operations closely, adhering to national and international codes and certifications, and constantly measure impacts on the environment.

5. Silent as the sun
While wind turbines are excellent electricity producers, most produce significant noise. Residents living within the vicinity of wind farms have reacted to high noise levels, something which a number of people are unable to get used to even after a long time. PV panels are not considered a nuisance as there are no moving parts to generate friction or sound.

The sun is quiet, and so are PV panels.

All this points to PV panels as being greener than most other renewable energy sources, both in terms of manufacturing, operating, environment disturbance and emissions.

Now that’s something to make a noise about!

This theme reflects Yingli’s strength and belief in independent innovation and commitment to a continuous upgrading of its development process.
Representatives from the State Ministry of Science and Technology, Energy Administration of Hebei Province, Science and Technology Office of Hebei Province, Baoding City Government, China Development Bank and North China Electric Power University attended the opening ceremony and inspected the latest cutting-edge developments in photovoltaic (PV) technology.
Divided into five major exhibition areas with 29 booths, the Expo features more than 400 recent innovation achievements from the Yingli Group. These included projects in many fields such as PV manufacture, flywheel energy storage, PV system and application, associated industries and service industries. All these innovations showcased Yingli’s ability to stimulate employee engagement and innovation to help increase the competitive strength of its products.
Five Year Plan
As Chinese General Secretary Mr. Xi Jinping has pointed out, “Innovation is the first driving force to lead the development, grasping innovation is grasping development, and seeking innovation is seeking the future”.
The Technology Innovation Expo is a vivid reflection of this, by helping build existing Beijing-Tianjin-Hebei synergy innovation community through practical action. The Hebei Province government has set goals in setting creative platforms, opening innovation resource sharing, collectively tackling key fields together and building collaborative innovation systems.
Additionally, the Hebei Province Technological Innovation 13th Five Year Plan lays down a framework that proposes that by 2020, the rate of agricultural, scientific and technological progress should reach up to 60%, and that Hebei Province should aim for a top 15 place in the country for the synthesis index of technology improvement.
Following the success of the last two Expos, the Third Technology Innovation Expo showcased developments in display technology innovation, business model innovation and management aspects that had been achieved in recent years.

Star Products
At the Expo, Yingli showed its new generation PANDA solar cell, based on the ion implantation technique. As the first PV enterprise to successfully produce n-type high efficiency bifacial modules, Yingli has upgraded the first generation PANDA solar cell by using the ion implantation technique and also simplified the production process to produce a star product.
The generated output of TwinMAX Series modules (60 Cells) that adopts new generation PANDA solar cell exceeds 300W from the front. The back can increase energy yield up to 30% on optimized installation sites, with an actual generated output of more than 380W and power generation efficiency of more than 24%.
The product has been successfully deployed at the China Shanxi Datong 50MW advanced technology PV demonstration project. It is currently the largest n-type monocrystalline double glass modules application project in the world.
05
Collaboration And Efficiency
Moreover, Yingli demonstrated new initiatives across the industry in chain collaboration innovation, applied diamond wire cutting technology and black silicon, PERC cell technology. Together, these help drive polysilicon cell efficiency of more than 20%, and a reduction in PV module cost of 25%.
Other innovation developments include intelligent PV power station operation monitoring systems; PV cleaning robots; enhanced automation and intelligence of PV power stations; and high efficiency and serialization of distributed household PV power generation system that can reach millions of households.
The Expo’s “PV+” exhibition area focuses on the innovative application of PV technology, displaying new PV power generation terminals and more. Other highlights include a showcase of the “Yingli Craftsman” and “Obtain benefit from Management” selection and commendation criteria. For example, the company issued a cost reduction and benefit improvement proposal to its staff in July and only one month later in August all departments had implemented 96 proposals and made profit of more than 440,000 yuan.
06
Pioneering Innovation
Referring to the “Obtain benefit from Management” initiative, Ming Li, from Yingli No.1 Test Workshop, said it not only helped pioneer a sense of innovation, “but also inspires our enthusiasm and initiative towards work through bonus and encouragement.” Ming, responsible for an automatic test line merging project, said the tight integration of various testing equipment will help Yingli save both manpower and earn 42.3 thousand yuan per month.
“Grassroots innovation as seen in the ‘Yingli Craftsman’ penetrates the spirit of innovation into every aspect,” said Dr. Dengyuan Song, Chief Technology Officer of Yingli Green Energy. “We can display innovative achievements through activities like ‘Yingli Craftsman’ selection, and from its unique ‘Import-Digestion-Absorption-Re Innovation’ innovation mode’.
Green Future Achievements
Through all these new technologies and initiatives, Yingli has become a Green Future pioneer and expert. It has applied 13 PCT international patents, 2056 China patents, and 1577 patent licensing agreements as well as working as key editor on 77 international and national industrial standards.
Thanks to its ongoing pursuit of new, more efficient and more innovative production and research technologies, Yingli has been awarded National Innovation-based Pilot Enterprise, and ranks first in the Chinese PV industry for number of patent applications and authorizations.
It has engaged in close collaboration with State Key Laboratory of Photovoltaic Materials & Technology, and the National Energy Key Laboratory for Photovoltaic Technology and has taken 23 national key technology projects, such as 973 and 863, and 108 provincial technology projects.

It is losing its coral reefs.

“Coral bleaching is expected to occur more often and with greater severity in the future, making it difficult for corals to recover between bleaching events. As a result, the abundance of living corals on reefs is likely to decline in coming decades,” reads a statement on the Great Barrier Reef Marine Park Authority website.

Elsewhere, marine degradation is evident too, from the Caribbean to the Coral Triangle – an area that stretches from Malaysia, the Philippines to Papua New Guinea. The Coral Triangle is home to 75% of known coral species.

The Intergovernmental Panel for Climate Change projects coral reefs to undergo “long-term degradation” due to bleaching and will impact ecosystem services, which includes fish that provides nutrition. WWF reports that more than 120 million people in this region rely on the marine resources.

When we see images of ghostly white corals instead of colored and vibrant ones, what goes through our minds?

Coral Bleaching
Corals being rather fussy animals react to temperature change, just like how we shift uneasily when it gets too warm, and perspire. We can certainly dash for the remote control to switch on the air-conditioner to stay cool. Corals can’t.

Apart from hikes or dips in temperature, corals get stressed when there are changes in light and nutrients. They expel the symbiotic algae living in their tissues, causing them to turn white. This causes the “bleached” coral to starve for food and become vulnerable to diseases.

Infographic11 (1)(Image Source: )

The average global temperature on Earth has increased by about 0.8 degree Celsius since 1880, and is projected to climb higher. Since global warming is causing massive coral bleaching, can we do anything about it?

Are you and I personally responsible for temperature rise, the loss of habitats, and vanishing species? In part, yes. While a small quantity of greenhouse gases is produced naturally, the majority is emitted by human activities. Our lifestyle today relies on energy, and much of it comes from the burning of fossil fuels.

It is the use of fossil fuels such as oil, gas and coal that continues to feed the global crisis. Toxic gases released from the extraction and processing of these fossil fuels continue to cause air, land and sea pollution. The gas emissions contribute to the “greenhouse” effect, hence a warmer planet.

For sure, switching from the use of oil and gas to solar powered heat and energy is a positive step towards cutting out harmful emissions like carbon monoxide, carbon dioxide, nitrogen oxides, sulfur dioxide, and other pollutants, even small particulate matters that get caught in our lungs.

. However the over reliance of carbon materials to power our homes, offices and cars has tipped the scale to cause ambient temperatures to rise.

Biodiversity Threats
Natural habitats have been destroyed and continue to be harmed due to new climate patterns such as variations in rainfall and longer, warmer summers. As a result, a number of species fail to adapt to the changed environment and experience disrupted patterns of seasonal breeding. Some may migrate to cooler areas, while others can’t.

According to WWF scientists, “most species on this planet (including plants) will have to ‘move’ faster than 1,000 meters per year if they are to keep within the climate zone which they need for survival. Many species will not be able to redistribute themselves fast enough to keep up with the coming changes. These species, as far as we know given present knowledge, may well become extinct.”

WWF has described global warming to have a “winnowing effect” on ecosystems. While it filters out species that are not highly mobile, it also favors “a less diverse, more ‘weedy’ vegetation and ecosystems that are dominated by pioneer species, invasive species.”

It is a fact — we are largely responsible for climate change and the knock on effect on plants, animals and livelihoods.

Beating Climate Change
People and businesses can act collectively to reduce temperature rise by becoming energy efficient, and even generating alternative and clean energy.

The Paris climate agreement has urged all to do what they can to avoid catastrophic climate change by limiting global warming to 1.5C to 2C compared to the pre-industrial era by year 2100.

Participating governments of the agreement have committed to replace fossil fuels by clean energy in the second half of this century. Japan, for instance, aims to derive 22% – 24% of its electricity production from renewable sources by 2030. The European Union hopes to reach 27% of its final energy consumption with clean energy substitutes.

In each country, companies are making the difference.

amcorp

Malaysia’s largest solar farm, , generates about 13.6 million kWh of clean electricity each year with Yingli Solar 250Wp modules. The clean energy is fed into the power grid, reducing around 25,000 tonnes of carbon dioxide emissions each year — comparable to energy guzzled typically by more than 3,300 homes in Malaysia each year.

Over in New South Wales in Australia, has installed 990kW rooftop photovoltaic system with Yingli Solar to harness energy from the sun. The carbon emission eliminated is equivalent to taking 306 cars off the roads each year!

Less pollution, less carbon emissions, curtailed temperature rise — yes it is possible to achieve all of these. And they help corals thrive in a kinder world.

It took more than two centuries to perfect the art of tapping energy from the sun. Yet the inspiration behind solar panels has not changed over time – that brightest of stars – the sun!

The sun’s unleashed energy gives us life. Plants use sunlight to make their own food, which in turn feed animals. Humans depend on plants and sometimes animals for nourishment.

Trapping this abundant and constant solar energy can also help channel its effects for specific needs. With the use of “solar collectors” such as photovoltaic (PV) cells on rooftops, children in remote places can study at night. With bigger PV panels on stadiums, fans can enjoy an uninterrupted game of sports, long after the sun has set.

It’s true solar technology has come a long way. But before shiny blue patches became a common feature on the top of houses and office buildings, there was a long and rich history of how the sun’s heat and light energy became a much needed power source.

YGE-Blog-Solar-Collectors

Solar Collectors
As far back as the 7th Century BC, people used a magnifying glass to concentrate the sun’s rays to make fire. And they also burnt annoying ants! By the 3rd century BC, the Greeks and the Romans were frequently using burning mirrors to light torches during religious ceremonies.

Around 212 BC Greek scientist Archimedes used a cunning device to deter the Romans from besieging Syracuse. He used the reflective properties of bronze shields to focus the sunlight on the approaching wooden ships out at sea. Within minutes, they were on fire! No wonder Archimedes is credited as the father of concentrated solar power.

Over time people built homes and designed their living spaces to draw in as much sunlight as possible. Justinian l, the Byzantine Roman Emperor, saw it as a basic right for people to get sun exposure. He initiated “sun rights” in a set of laws called the Justinian Code (AD 534) to ensure that there were sunrooms in houses and public buildings to give warmth and natural light.

An invention by Swiss scientist Horace de Saussure in 1767 saw him build the world’s first solar collector. This invention helped sustain Sir John Herschel, a scientist, astronomer and explorer, as he used solar power to cook food during his 1830s South African expedition.

The Stirling engine as we now know it was the work of a minister in 1816. Robert Stirling, when not at the Church of Scotland, built heat engines at home that were later used in the Dish/Stirling system, a solar-thermal electric technology.

From glass and mirrors and solar collectors, the invention of solar powered devices was made possible only when the next hurdle was tackled – conductivity.

77334.com

Solar Conductors
The 19th century saw a series of progressions made in improving conductivity so that more light energy could produce electricity.

In 1839, while experimenting with an electrolytic cell made up of two metal electrodes placed in an electricity-conducting solution, French scientist Edmond Becquerel discovered that electricity-generation capability increased when exposed to light. This is the first recorded instance of the photo (light) voltaic (electric current) or PV effect.

The pursuit of light-induced conductivity picked up pace in the later half of the century. In 1873, Willoughby Smith discovered selenium’s photoconductivity. Three years later, William Grylls Adams and Richard Evans Day discovered that selenium produced electricity when exposed to light. This was an eye-opener – something solid could convert light into electricity without the additional property of heat or the aid of moving parts!

Less than a decade later, selenium research reached a turning point. American Charles Fritts used a thin layer of gold to coat the semiconductor selenium. This brought about 1% conversion efficiency – direct from light to power. While the materials used were too costly for mass production, Fritts can be credited as the first person to conceive the idea of electrical solar energy.

This triggered a wave of photosensitivity improvements into the early 21st century. New materials such as copper and cuprous oxide were introduced that led to William J. Bailley of Carnegie Steel Co. to invent a solar collector with copper coils and an insulated box in 1908. This design still remains today.

Enter silicon. In 1918, Polish Jan Czochralski found a way to grow single-crystal silicon which led to a flurry of scientific research and experimentation.

In 1954, Daryl Chapin from Bell Telephone Laboratories sought to find a way to get telephones to work in remote places – 50’s era batteries could not thrive long in hot and humid areas. His colleagues, Gerald Pearson and Calvin Fuller, were working on building a solid state rectifier (one that transforms AC to DC) with crystalline silicon. As that time, PV cells were made of selenium, which could produce only five watts per square metre, or a 0.5% conversion efficiency. Chapin wanted 6%!

Over time, the researchers introduced gallium into the crystal matrix, and coated that in hot lithium. While shining a light on this crystal, Pearson discovered that the light energy induced an electric current! Another Eureka moment – Fuller vaporized phosphorus onto the ensemble, allowing for the target 6% efficiency! They now got their phones to work in far away places.

This signalled a new era of material improvement for the everyday use of solar PV cells.

YGE-Blog-Solar-Inventions

Solar Inventions
Post War in the mid-20th Century, researchers saw the need for industry growth and social improvements, hence research revolving around the sun took on greater importance.

In 1964, NASA launched the first Nimbus spacecraft, which was a 470-watt PV powered satellite. Just a year later, Peter Glaser conceived the idea of the solar power satellite station. Thanks to this new development in space and PV technology, we can explore the unknown, predict the weather and connect ever faster with any part of the world.

The 1970s saw the growth of solar powered applications for everyday use, especially in remote places. In 1972, a village school in Niger received a gift from the French – a neat educational television powered by a cadmium sulphide PV system.

The University of Delaware in 1973 built the world’s first residences, called Solar One, using PV and thermal hybrid systems. Today, you can find amorphous thin film solar cells on windows and vertical walls – these make it possible for even greater sunlight collection. Coupled with lead acid or lithium ion battery advancements, storage of energy for electrical conversion is becoming easier and more feasible for off-grid living compared to a decade ago.

In 2006, the sporty Tesla Roadster became a game changer in the electric car space. Founders Martin Eberhard and Marc Tarpenning experimented with jaw dropping designs and state-of-the-art parts that included heated seats, satellite navigation and the lithium-ion batteries. The quiet vehicle had an incredible acceleration of 0 to 97km/h in under 3.9 seconds and could travel as far as 320km on a single charge.

Solar PV has also become commonplace on the high seas with hybrid electric-motorised boats and yachts using the sun’s energy for cruising power. The largest yacht, according to the Guinness World Records in 2010 was the MS TURANOR PlanetSolar, measuring 31m long and covered by 537 square metres of 93 kW solar panels. It also made the fastest transatlantic crossing at 14 knots tops completely under solar power in under 27 days.

have also replaced fossil fuel dependency in many parts of the world, reducing pollution and carbon emissions as homes and offices enjoy clean energy. Ghana and neighboring countries will receive up to 100MW ground-mounted solar farms and a further 50MW of rooftop projects through a .

Portable solar gadgets are now getting funky. Fancy a solar bikini? New Yorker Andrew Schneider’s solar bikini allows the sunbather to charge a smartphone or media player while lying on the beach. The 2011 invention has 40 thin and flexible PV strips sewn together by a conductive thread, ending at a USB port.

Now if that doesn’t wow you, maybe this will. Beijing’s proposed electric “hover bus” will be partly powered by PV panels, transporting 1,200 people to their end destination by gliding over cars stuck in traffic.

Now that is surely an invention on the move! In the words of eco-explorer Raphael Domjan of PlanetSolar, “We must motivate engineers and scientists to develop innovative technologies and show that the impossible can become possible.”

With global technology innovators like Tesla, LG Chem, Samsung, Panasonic, Aquion, Lishen and RedFlow all bringing products to the world and focusing on Australia as their launching stage – tells you that Australia has captured the attention of renewable energy innovators and enthusiasts around the globe, why?

  • Nation-wide high retail cost of electricity.
  • Australia’s leadership position of having one of the highest penetrations of residential solar per capita in the world.

This opportunity is for us to demonstrate to the world how the average family home can take action in being conscious about the way they generate, harvest their energy needs and demonstrate how an empowered homeowner can have a seat at the table of the traditional big energy companies.

The advantages of this shift is predicted to create new ways of thinking about how we create our buildings, but ultimately how we can cut the umbilical cord of traditional services and live in a new societal era.

Below are some factors that should be properly considered before signing up to a new storage solution:

  • Although batteries have been in use with for a long time, many of the new offers are new to many markets and do not have a lot of real-world testing information.
  • Everything is about ‘energy density and discharge’. For every dollar you spend, the more you can store and the quicker you can access is essential.
  • The cost of storage is considerably high and the Return On Investments (ROIs) are high at the moment. It is expected to be .
  • As ROIs are the economic driver to make this solution viable, the performance of your grid-connected solar system (ie, your free contribution of energy from the sun) is paramount to maximizing your ROIs and its longevity.
上葡京

The majority of system owners are identifying the system performance by the cost and/or savings of their electricity bills, which can be vague.

Consider it like buying a car without a speedometer or fuel gauge, and you’re determining your performance based on your end of month credit card bill statement, your fuel bill is $450/month and you’ve recorded 23 hours spent in your car! The statement doesn’t show you the cost of fuel at each refill, the efficiency of each journey or any data that could suggest how you could make it more efficient.

Now, if you’re considering adding a storage solution, with it you might learn a lot more about your energy usage pattern, the amount that is delivered from your solar system and its performance compared with the energy sourced from the grid.

The grid is a constant which you can expect to charge you within the regulatory framework of pricing a rate for a period of the day, but you’re probably going to be hopeful that the solar system you have installed will generate the majority of your power needs, ensuring that the sun’s energy is filling up the batteries (for free) and not the grid.

Which is of course true, if you know whether the system is performing specifically and if its generation is align with the expectations made at the time of sale. If not, perhaps it’s prudent to get it checked.

There are a number of factors that can affect solar system performance over time, which can include, but are not limited to the following:

  • Obstruction of solar PV modules
    • Shading
    • Stick, twigs, leaves or bird droppings
  • Defects within the PV module
    • Yellow backsheet
    • Shattered glass
    • Connector fault or failures
  • Isolator failures
    • Burns out
    • Water ingress
  • Inverter
    • Over voltage trips
    • Over heating
  • Under-Performance

How do you know? What can you do?

Just like your car, if it’s not performing you should seek out a qualified (accredited) technician to conduct a series of checks. At conclusion, they’ll call you with their analysis and provide you a report. Your solar PV system should be no different, except to date there has been no standard or regulation for the assessment or verification of solar systems.

With a large market and many experts – there is a simple way to check with confidence. We have developed a specialized training program where accredited installers are trained, tested and accredited in the skills of fault-finding and maintenance of grid-connected solar systems.

Yingli Solar, which has been a quality and innovation leader since 1987 continues to strive in its delivery of providing “Affordable Green Energy for All™” If you’re interested in finding out whether your solar system is ready for storage – to arrange a system assessment.

Understanding carbon and how it affects the atmosphere helps with strategizing our move towards sustainable living.

We often hear about carbon footprint, but what does that really mean? Why the fuss?

Carbon footprint simply refers to the amount of carbon that is released to the atmosphere due to a particular activity. Driving a car to the supermarket releases carbon dioxide, probably carbon monoxide, and other polluting fumes from the exhaust pipe to the air.

Burning fossil fuels such as coal, oil and gas to produce electricity releases carbon dioxide, methane, nitrous oxide, soot and other noxious gases that trap heat in the atmosphere. They are called “greenhouse gases” because they stop heat from radiating from the earth’s atmosphere into space.

As a result countries worldwide have reported warming temperatures. 2015 was the planet’s warmest year since the 19th century, triggering heat waves, droughts, storms, hurricanes and flooding worldwide. And it is continuing to get warmer – that’s climate change.

Climate Change
Climate change affects all of us whether we live in the country or the city, both short and long term. The rough weather conditions mentioned have occurred in the United States, Europe, Asia and the Pacific. According to scientists, this will persist if we carry on with our polluting activities.

Climate change is not just about sweaty brows. It is about survival.

Apart from physical discomfort, health deterioration, damage to properties, relocation and disruption to work and living, climate change can be deadly during heat waves and flooding. And it will continue to upset the balance in nature particularly in food production and water supply.

Because of such unprecedented changes to the climate, more people will go without secured sources of drinking water and food. Climate refugees fleeing such conditions will cause greater migration issues, leading to worsening security, economic and political problems.

Is Carbon Bad?
Carbon is a natural element. It is found naturally in three crystalline forms: coal, graphite and diamond.

We need carbon for survival. As a non-metal, it is found in all organic compounds, including rocks (limestone) and dissolved in natural water. Humans are organic, carbon-based life forms. The atmosphere too has carbon in the form of carbon dioxide. The fuel we burn for power or warmth, are all made out of a mix of hydrogen and carbon compounds.

So carbon itself isn’t a baddie. Carbon becomes a problem though, when we burn too much of it. Our atmospheric carbon content has exceeded safe limits, and this is why, globally, we cannot ignore the fact that human related activities have escalated the carbon levels in the atmosphere.

We cannot run away from climate change effects. We can, however, help lessen the problems or mitigate the impacts with some lifestyle changes. This means reducing our carbon footprint.

The Carbon Culprits
Imagine life without power sources. Can we do without vehicles, the air-conditioner, heaters and many more?

Modern living has made us totally dependent on energy to be able to read at night, email a report or even put food on the table. Depending on where you live and the power supplier, the source of energy could be emitting tonnes of greenhouse gases.

Conventional power plants use coal, oil and gas to produce energy, which is pollution at source. The use of electric cars instead of fuel-powered ones helps prevent air pollution and reduce carbon emissions at the tailpipe, but not completely so, if the electricity used was generated by a fossil fuelled power plant.

In developed countries, the residential sector is often a top energy guzzler, followed by commercial, transport and industry sectors. Machinery and appliances used in buildings consume vast amounts of energy, which is why taking concrete steps to reduce your carbon footprint is a good idea.

The smart answer is renewable and clean energy sources, such as solar, wind and geothermal energy, which tackle the carbon culprit right from the start.

Global Commitment
In April 2016, more than 175 countries have agreed to take steps to hold the increase in the global average temperature to below 2°C above pre-industrial levels, and to try to limit the temperature increase to 1.5°C above pre-industrial levels.

Your country, in signing the on 22 April, has pledged to reduce greenhouse gases emissions.

“The world is in a race against time,” U.N. Secretary-General Ban Ki-moon said in his opening speech in Paris. “The era of consumption without consequences is over,” he said. ”We must intensify efforts to decarbonise our economies.”

The Three Strategies
Three strategies exist to help homes and businesses keep their carbon footprint down while maximizing returns that include social and environmental benefits.

  • Avoidance
  • Conservation
  • Generation

Before choosing your strategy, be clear why you wish to save energy. Your motives for energy saving could be any or a combination of the following:

  • Lowering power bills and saving money
  • Reducing your carbon footprint and environmental impact
  • Boosting the value and marketability of your house
  • Raising the reputation of your business
  • Improving the social and environmental conditions of communities

AVOIDANCE takes time to develop and involves breaking habits. Instead of overworking the radiator to stay warm, putting on extra layers of clothes saves energy. Most of the heat of the human body is lost through the head and exposed hands and feet, so putting on thicker socks and a woolen cap can keep you warm and put more dollars in your pocket!

Walking or cycling instead of driving to the supermarket or work is another example that will also keep you fit. Avoidance can be difficult and requires determination and will-power to switch to a different way of doing things.

CONSERVATION often involves thinking out of the box. Adding a layer of insulation to walls, upgrading from single to double window glazing and using heavy dark curtains and shady plants to help cool interiors are all effective in reducing greenhouse gases. Plants and trees take in carbon dioxide, acting as a carbon sink.

Conducting an energy audit will locate areas of hot or cold air leakages within your home. An auditor can be hired to do this who can pinpoint leaks and recommend ways to conserve energy by changing behavior or upgrading and retrofitting. Bear in mind that as energy costs go up over time, the upgrading ideas become more cost-effective. Upgrades with a payback period of 7-10 years are generally considered good investments.

Most incandescent or filament light bulbs lose 90% of energy through heat generation. Compact fluorescent lamps (CFLs) typically use 70% less energy than incandescent lamps, hence dubbed as “energy saving”. But lasting even longer and consuming even lesser energy are light emitting diode (LED) lamps.

LEDs today cost only slightly more than CFLs and have 20,000-50,000 hour life span. That’s more than 20 years’ use at four hours daily.

So don’t think twice about buying energy efficient appliances, especially ones with good energy star ratings. This cuts down carbon emissions and slashes power bills too!

GENERATION of energy, the third – and most viable – strategy, requires investing in renewable energy such as to generate electricity. This fully or partially offsets energy consumption from the grid and can be used with a solar thermal system for hot water.

With today’s technological advances, sufficient energy can be generated even in cloudy conditions to heat and power almost any building, including sports stadiums.

In honoring our commitment to the environment and planet, we stepped forward and became . Since then, we have left a positive legacy in the host countries of Africa and Brazil, as the joint solar legacy projects with FIFA such as the and multiple solar-powered stadiums continue to serve the communities and environment.

And if wind conditions are suitable, installing a micro-turbine on the roof in combination with solar system can greatly reduce your carbon footprint.

So what are you waiting for? Start developing a strategy for action and get going towards more sustainable living.

上葡京-www.81707.com-www.8455.com http://blog.yinglisolar.com/?p=710 http://blog.yinglisolar.com/?p=710#comments Wed, 27 Apr 2016 03:05:04 +0000 http://blog.yinglisolar.com/?p=710 www.81707.com As one of the fastest growing industries, there are many opinions and marketing taglines used which ultimately result in many misunderstandings.

Below are contradictions that you may have come across before:

1. All solar panels look similar, are they the same?
With over 500 brands that have been sold within the Australian market (between 2011-2015), it’s difficult for even an experienced professional to tell the difference. Accepting the idea that the label or datasheet has typical information as below – doesn’t mean they’re all the same:

  • 10 year product warranty
  • 25 year performance warranty
  • Power class rating (eg. 250wp/260wp)

The manufacturers around the world have gained the majority of their market share through their ability to manufacture high standard products, which demonstrates a high level of research & development including exposure to different types of environment and life cycle tests. These are seldom regarded as important in the eyes of many retailers and consumers.

The best way to determine global exposure is asking for in other countries. Chances are if evidence can be provided that the products are used in larger projects in a number of other markets – there has been enough due diligence to suggest it will work for you in your market.

2. Kilowatts & Kilowatts – (kW, kWp, kWh)
Traditionally there is much confusion on this topic for non-technical buyers. Also, it’s commonly referred in the retail spaces that you are buying a system size.

For example, solar systems in Australia are sold as “5kW systems”, but really should be sold as 5kWp.

  • The ‘p’ indicates “peak”, as in the amount of power being generated at peak production (being 1,000 w/m2 irradiance of direct sunlight).
  • Kilowatts are the measurement of energy units. When referred as kWh (kilowatt hours), it means the energy used at a constant rate over a period of time.
  • Referencing of kW or kWp does not indicate the yield or likely performance over a day, week, month or year – providing an unrealistic outcome of the solar system’s potential. It’s like saying a car that drives at 200km/h is a “200km car” – where in truth it’s only highlighting the ‘peak performance capacity’.

Once again, if larger global projects have specified and used a nominated brand of product, it is because their independent and technical due diligence suggests there is high level of confidence in a manufacturer’s ability to consistently create a product that generates a reliable quantum of electricity generation year on year.

3. What does “Tier 1” mean?
The solar industry has struggled for years with a methodology to rank and assess the relative strengths of PV manufacturers. In the absence of a true quantifiable testing regime, many have resorted to the views of financial analysts. In many instances, the industry use this term as a mean of quantifying quality, without placed onus on any specifics.

The tier system is a ranking structure used by varying financial analysts and firms. The most commonly accepted definition is based on “bankability”, which ultimately is a determination based on whether projects using the solar products are likely to be offered non-recourse debt financing by banks.

Other definitions and interpretations of ‘tier-ranking’ have included theories around vertical integration of product, presence of a local office and support, all of which indirectly suggests a level of product quality or after-sales support.

Tier-ranking can be highly subjective without substance of what it actually defines.

4. Does the country of origin affect quality of a solar panel? German made or German engineered, is it better than all others?
The reference of a product’s country of origin is an age old method of oversimplifying quality, by providing an emotive feel good to buyers – which supersedes the requirement for further due diligence.

Solar PV has been one of the most rapidly expanding industries within a manufacturing sector for years, however with this rise, it has seen significant players trip, if not fall through this massive growth phase. Many manufacturers prefer to diversify their base and expand by opening many around the world. It simply isn’t fair to assume a quality of engineering or product based on the location of where product is assembled or where the headquarters of the business is operating.

It’s deceptive and misleading to suggest the quality of a product can be determined solely from its country of origin, especially if the suggestion is that a product made in Asia is created to a lesser standard, when compared with other non-Asian markets. In 2013, it was reported that over 90% of solar panels imported to Australia were made in China, despite the popular non-Chinese brands being prevalent in the offers from retailers.

With such high level of market penetration from solar PV brands from China, the quality gap is broad, making the importance of differentiating quality is why some manufacturers stay in business and others don’t.

5. Doesn’t all solar PV manufacturers provide the same warranty protection?
Australia is one of the world’s most dynamic retail residential markets, and with a flood of messages in the industry, it has been easy to think that if a solar panel offers a 25 years (performance) warranty, then you will be protected?

This is true, but only to an extent.

The 25 years warranty is a performance warranty pertaining to minimum expected performance or output year on year. This is separate to the performance of the system as a whole, which is subject to the system design and performance of other components.

Although many customers are sold on the belief that there would never be a fault, this is largely misleading and for the following reasons:

  • The technologies are well proven, so are installation done by people, and human error is always an unquantifiable risk.
  • Transportation risk can affect a product, it’s unlikely that defects from transportation show.
  • The technology is exposed to the outdoor environment, which is subject to wind, rain, dust, dirt and bird droppings, trees, twigs, possums – just to name a few.

So, do buyers ask – what is the process in the unlikely event of fault or failure?

  • How do I know?
  • Is the system being monitored? Is the monitoring only for the homeowners viewing, or is there a back to base system which communicates to you, the owner and also the installer?
  • What happens if you don’t know or can’t find the installer?
  • Who supports the installer?
  • What are your consumer rights?
  • Do the major component suppliers have a local representative? If so, who are they and what is their phone number?

Performance warranties are valid if there is adequate evidence to suggest your performance is less than designed. Regardless, an assessment will need to be done, preferably by the company or installer who sold you the system. If they cannot be found, then buy from a reputable and industry-qualified professional.

6. It’s all about price!
It’s a common reality in buying anything, when in doubt, select the best value for money. This suggests that value has been presented, on the contrary, the lowest cost solar is no exception. In many instances, the lowest cost components generally require a higher level of repair and replacement – the consumer may not be aware of this, and it will cost them more in the long run.

With any capital investment, you want certainty in the unlikely event of any fault or failure, above and beyond long-term guarantees.

It is strongly encouraged that you conduct research about some technical differences, and have a list of questions about how you will receive after-sales support and service. The reality is if you don’t understand the differences, the only value you can see is one based only on the price.

7. Capabilities of product and installer
With such an expansive list of products and installers – it can be difficult to know the good from the not so good. The buying market has no point of reference to determine if a solar panel or inverter is good versus average – as it is based on Clean Energy Council’s approval.

Aside from generic references, which are meant to instill confidence, like “we have installed over 3,000 systems”, there is no means for buyers to understand the experience or quality of services they are paying for.

One of the biggest concerns is whether the installer is based locally, and we suggest you to ask these questions:

  • If the installer does not have a local office, have you enquired their service standards and response times in the unlikely event of a fault?
  • What is the policy and commitment of the after-sales service?
  • What is their responses time frame?
  • Is there a difference in receiving service within 48 hours or over 4 – 8 months?

There are many fantastic and integrated installers in the market but unless a series of questions are being asked, how will a solar buyer know? The age-old method of testing this is to ask for references, preferably from people in similar situations as you, and a customer who had bought from them previously.

We encourage those interested in solar to do their research, the team at are available to help answer any products, services or technical questions you may have!

Well, some homeowners go solar to save money while others do their part for the earth. Whatever the reasons, harvesting the solar energy for your home brings you a host of benefits that you simply cannot refuse.

There are a number of reasons why homeowners opt to harness energy from the sun with photovoltaic (PV) systems, and here’s a few.

1. Save Money
Tapping free energy from the sun now and for the next decade or two means paying less for electricity in the short term, and gaining more than the cost of installing the system in the long term. As solar energy generates mostly in the middle of the day, it’s generally offsetting the maximum peak electricity rates, which is seeing you maximizing your savings. Many federal governments have policies in place, which incentivize homeowners opting for renewable energy. Not only are you likely to receive an upfront rebate or an income tax credit, you’re also likely to receive a bill-credit for excess energy generated that is sent back to the grid. Why not ride on such incentives to not just save money, but also make a few extra dollars?

2. Add Value
New research conducted in Australia by found that 85% identify solar system as something which adds to a property’s value. With a stronger sense of green living among consumers, there is an increasing recognition of solar system as a valuable asset. Studies have shown that home buyers and renters are willing to pay more to live in a property powered by solar energy, hence you’re likely to gain a competitive edge in the market if you’re looking to sell or lease your property. That’s definitely good news for homeowners looking to increase the appeal of their property.

3. Get Connected
Enjoy countryside living without having to worry about power. Seen a plot of land that is perfect but sited away from the electrical grid? No problem. Homeowners of remote places can harness to power their daily consumption, and even allow excess electricity to be saved for future use. So you need not worry about the noise and flammable risks that are common in the conventional power generation solutions such as the diesel generators.

www.81707.com

Mike in rural southeast Victoria, Australia built his dream home and operates his small hospitality business out in that’s one kilometer away from the grid. Instead of dishing out AU$50,000 in costs for connecting to the power grid, Mike opted for a better solution – he went solar! A nifty self-sufficient system comprising ground-mounted 8kWp solar panels out in the yard along with inverter, batteries and a back up generator were housed in a purpose-built shed with ventilation. That took care of all the electrical energy needed, not just to power his home but also two Bed & Breakfast ventures, all out in the idyllic country setting. Going off-grid, according to Mike, was a “no brainer”. Not only was the renewable energy system expense equivalent to the mains electricity costs, Mike will benefit from an energy yield of 10,000kWh annually for many years to come – all from the sun!

4. Stand Out
If a face can launch a thousand ships, then a cool house can launch a thousand smiles! Stand out from the rest by tapping the sun’s energy in places no one has thought of before. Solar panels can be considered aesthetic too in the way they are mounted. Not just on the rooftops but on the side of a house or garage with angled brackets or even out in the garden next to the greenhouse. Sustainability at the core of design has led to the rise of green buildings and even zero carbon homes. Wind turbines are great for generating renewable energy for neighborhoods as well but they are often shunned by residents mostly due to aesthetic and noise reasons.

5x4 Project 3

The unique in Victoria, Australia was designed to tap the sun’s energy in every possible way to minimize its carbon footprint. The 4 kWp installation comprised of 15 solar panels mounted at three different angles on the rooftop and another set of six panels affixed vertically onto the building’s northern facade. The split design of the solar system was made possible with microinverters and a complete home energy storage system enables the homeowners to enjoy electricity at night. You can even watch how much this award winning house generates energy daily, made possible by monitoring devices and software.

5. Be Responsible
By choosing to go solar, you help prevent the on-going pollution that occurs with conventional energy production such as coal-fired plants as well as oil and gas extraction. Fossil fuels emit carbon dioxide and other harmful greenhouse gases that contribute to changes in the climate and extreme weather changes, like drought and flooding. Globally, rising temperatures have been recorded, largely due to human activities. Important animal species are increasingly under threat because of such unprecedented climate change, and some sadly have gone extinct. So in opting for solar for heating or cooling at home, you are doing yourself, your children and Mother Nature a big favor! In the case of Mike’s solar-powered home and Bed & Breakfast accommodation, as much as 13 tonnes of carbon dioxide emissions are avoided each year. Being responsible to the environment by going solar is easy.

6. Plan Ahead
The future has never looked brighter with solar on your rooftop! Long lasting, durable and reliable, solar PV modules can be used for 10, 20 even 50 years. come with a limited product warranty of 10 years; a limited power warranty of 10 years at 91.2% of the minimal rated power output; and 25 years at 80.7% of the minimal rated power output – all subject to the warranty terms and conditions. This means that the investment you made now will see you through well into retirement where you don’t have to worry about paying huge electricity bills. With regular maintenance and occasional replacement of parts, solar PV systems are a wise long-term purchase to make now. So the sooner you go solar, the better!

…about Product Registration; After-Sales Support and What happens in the event of a recall.

, the world’s electronic giant has an extremely high level of quality assurance throughout the design, manufacturing and after sales support. Recently they announced a voluntary recall of chargers for a range of their products. As a key component of their products, owners would likely place full confidence in the supplementary products as much as you would place to the primary products.

Identifying the batch defect, notifying the public and providing them with a complimentary replacement highlights the importance they place on rectifying product issues and customer support. The crucial component of this is apart of the in-store exchange process where a serial number must be provided and confirmed.

The question must be asked, why is the serial number so important?

Surely as a matter of customer service they could just exchange the charger for a new one. Unfortunately Apple, like many premium consumer electronic manufacturers have experienced a lot of competition from original equipment manufacturer (OEM) and in the interest of keeping with their product integrity – they want to ensure they replace only genuine accessories.

An important factor to consider here is that this incident raises a number of concerning liability issues. If the device is considered to be sub-standard, that although final responsibility sits with a manufacturer, states that the commercial retail is responsible for the damage caused by the product. Normal legal limitations like remoteness of the damage can apply but, that aside, potential liability is uncapped. Meaning, that if a charger fails and burns down a building, the retailer could potentially wear the claim and they would need to pursue their right of recovery from the manufacturer.

Now to the solar industry – what is it we could learn from this?

are now a common sight across Australian homes. Solar PV systems are electrically charged systems that will generate every day of the year.

In the Australian solar industry, the key products used, can filter through many hands before they end up on your house. It’s important to identify the parties that are responsible for the products importation.

Since 2010 over 500+ brands of have been installed on Australian roofs and connected to over 200+ solar inverter brands by any of the numerous retailing companies, which likely either employ or subcontract one or a few of the 4,000+ .

These installers, who are the first liable party for the quality of the installation either, subcontract their services to a solar retailer or contract directly to you. They buy directly from the various of solar wholesalers present in the market and in a few instances, some buy directly from the manufacturer – and although statutory information is required; it doesn’t include information about the local agents who will support the product.

The common assumption by many buyers is that all solar panels are protected by a ’25-year (performance) warranty’ and with this claim; very little due diligence is placed on the after-sales support or liabilities the wholesaler or retailer assumes in this process.

Under the Clean Energy Council (CEC) , the accredited installer is liable and responsible for the electrical works, connection and that the system is installed in compliance with Australian standards. Australian Competition & Consumer Commision (ACCC) requires the retailer (contracted party) carries the bulk of the legal responsibility to remedy a claim. Outside of a public and products liability insurance, many installers cannot guarantee their service indefinitely, as there are no known underwritten insurance policies protecting the consumer. If you fail to be protected by the retailer, the consumers last chance is to contact importer or manufacturer of the electric/electronic goods and seek assistance under the manufacturers warranty.

In the case of Apple, this is really easy, as they have numerous retail shopfronts and dedicated local service centres but unfortunately the same cannot be said for solar.

Questions to this effect are seldom asked or presented to buyers, indicating the identity of entities both responsible and liable for supporting the key components let alone presented in the contract or post-install design pack.

Why are the serial numbers important?

For all residential installations in Australia, to obtain the Federal Government rebate an accredited installer needs to capture and submit the serial numbers of the for the trading of Small Scale Technology Certificates (STC) as listed in regulation by the Clean Energy Regulator (CER). Commonly known as the Federal Government Rebate.

An unfortunate reality is that this information is not shared back with the manufacturer / importer for registration post-installation. Meaning should an unlikely event, such as a known defect, and a voluntary recall from the product occur, only your installer / retailer would have access to knowing which products were sold to which customers.

The power of the serial number on your module and inverter allows the system owner to make a product specific enquiry with the manufacturer – which is as important as the power generated from your solar system.

So, without sending you into a fit of frenzied fear, the important thing to consider is not whether products is likely to fail – but how can you be supported if a failure occurs?

If your considering a solar system, understand ‘buyer beware’ and ensure you receive answers to questions, such as these:

  • Who are the liable parties for the importation of these goods?
  • Does the component (panel, inverter & isolator) manufacturer(s) have a local office? If so, what are their contact details?
  • If an unlikely fault occurs who do I call, what is the after-sales processes? Are there costs for this service?
  • At completion of installation will you supply the serial numbers of key components?

The sheer growth of solar energy, has seen a myriad of solar retailers appear. Its essential for them to present a level of integrity and support, their role in your systems design and installation is paramount, especially if you’d like the comfort of after-sale support for the years ahead.

As a growing industry, we fully understand the need for solar buyers to source a competitively priced solar system – but in the absence of asking the right questions at the time of purchase, you may end up buying a more expensive system than you expected.

Recently it was reported that there are more solar panels than people in Australia (that’s 23.2 million solar panels), which is a truly remarkable achievement for renewable energy and for homeowners taking control of their energy bills and generation – which is why more than ever, ensuring that you have captured accurate records of your solar system design, components and expected generation are key to ensuring that you’re supported, just like a customer from Apple.

A field lit by solar power, to be exact. The club team’s stadium now meets 100% of its energy demand with a recently installed by our partner, . What does this mean for sport culture in Costa Rica? It means that sports leaders are recognizing the savings that solar can provide, especially for stadiums and training facilities that have high electricity requirements to operate and to light the fields.

Enertiva installers inspect their work. The project was commissioned in May of 2015.

Enertiva installers inspect their work. The project was commissioned in May of 2015.

The rooftop project for this stadium, Estadio Alejandro Morera Soto, was commissioned and installed by Enertiva in May 2015. La Liga estimates that the 260 kW system will save the club eighty million colones (USD $148,000) in electricity costs each year. Completion of the project makes this stadium the first in Central America, Mexico, and the Caribbean to be powered by solar energy.

Will this establish a precedent for Costa Rica’s 12+ stadiums? The stadium, known as “La Catedral” or “The Cathedral,” gets its affectionate name from the fact that it is one of the oldest and largest stadiums in Costa Rica. An institution since 1919, the stadium is quickly approaching its 100th anniversary.

From the Maracanã Stadium’s 390 kW system in Brazil to the in the United States, La Catedral is one of many sports facilities throughout the Americas switching to solar. For some, cost savings are the major incentive, and for others, a commitment to sustainability and a clean energy future is the driving motivator.

“With this initiative we aim to be environmentally responsible for the fans of the club and Costa Ricans in general,” commented Raul Pinto, President of La Liga. The club’s transition to alternative energy is an important contribution to the country’s goal of being carbon neutral by 2021.
