Rain insufficient for removing tree pollen from solar panels
An analysis by NREL in North Carolina reveals that various types of tree pollen can reduce solar panel efficiency by over 15%. Unlike the immediate improvements assumed to follow heavy rain, recovery of performance post-pollen season is gradual. Manual cleaning post-rain can boost performance by 5% to 11%.
China’s air pollution reduces PV production potential by up to 13%
If China could travel back to the 1960s with its 2016 PV generation capacity it could harvest an additional 14 TWh of solar power, according to a study by academics at universities in Switzerland and the Netherlands. With a mixed record for reducing pollution, the country’s solar fleet output appears to be drastically affected by dimmed solar radiation.
