US scientists claim clear-sky irradiance model provides better results for module testing
Researchers at the American Institute of Physics have used the clear-sky irradiance model developed by the National Renewable Energy Laboratory to measure the degradation rates of solar panels at a testing field in Germany over five years. The scientists say the model, when combined with real-world data, offers an efficient tool to evaluate the aging of PV technology.
Longi unveils results of bifacial module test
The exercise, conducted on Longi PERC bifacial modules by Germany’s TÜV SÜD at a test field in China, showed surprisingly higher gains in panels getting light reflection from painted-surface and grassland albedo. It also showed, Longi claimed, bifacial panels operate at lower temperatures than single-sided alternatives.
