Given all the variables involved, it’s not surprising that predicting the efficiency of solar panels over time is so challenging. Every residential solar photovoltaic (PV) installation is unique. The amount of sunlight exposure and air temperature may not only vary from installation to installation, but from day to day.

A team of engineers from Stanford University in the US has successfully managed to improve the performance of solar PV materials by using a nanomaterial called nanocrystalline silicon, tiny spheres of which have been used by the scientists to improve the light absorption of solar panels. (more…)

Apple’s image in terms of social responsibility and environmental friendliness is not as pristine as its reputation with geeks is because of reports on the conditions offered to factory workers in China and the company’s poor recycling record.

However, Venture Beat reports that the company’s (more…)

In recent weeks, Vote Solar and our Arizona partners have sounded the alarm about legislation that would stop the state’s clean energy progress in its tracks. (See our previous blog post and a recent Arizona Republic editorial to learn about why Rep. Debbie Lesko’s HB 2789 is such a red-alert threat to the growth of solar markets in the state.) (more…)

New Energy Technologies’ SolarWindow is a promising photovoltaic solar technology that we have been following for a while. SolarWindow’s promise is to generate electricity on see-through glass. In conjunction with the National Renewable Energy Laboratory, the company has successfully fabricated the largest-area organic photovoltaic (OPV) module (more…)

Renewable energy advocates always say that official incentive is key to promote the adoption of clean energy. Ukraine, in Eastern Europe, is the latest case in point.

According to a Bloomberg report, the country’s solar power capacity will double this year, thanks to the completion of Europe’s largest PV solar plant and (more…)

A cool-down in European solar markets combined with an over-supply of panels from China has led to a massive decline in solar panel prices. Over the last year, prices for solar panels have fallen 50 percent. In the U.S., falling prices spell competition, and many solar providers are hustling to position themselves to take advantage of a rapidly changing solar industry.

The CEO of Gehrlicher Solar America Corp, Stefan Parhofer, said in an op-ed published by NJ.com that that the tariffs on imported solar energy panels proposed by some U.S. solar manufacturers would do more harm than good.

Parhofer’s company, an affiliate of a German solar (more…)
