(American Institute of Physics) In testing solar panels, the sun’s intensity, the spectral composition and the angle of light are important factors in understanding why certain panels are successful and others degrade more quickly. To address the knowledge gap in degradation mechanisms for various photovoltaic types, researchers performed tests over five years in which they collected weather data and panel performance information. The results are published in the Journal of Renewable and Sustainable Energy.
