The actual situation of rooftop solar power generation
Factors Affecting the Performance of Solar Power System
Solar cells perform better in the cold rather than in hot climates, such as if solar panels are exposed to 25˚C, which can be significantly different from the real outdoor situation. Hence whatever single temperature rises above 25˚C the solar panel output decays by about 0.25% for amorphous cells and about 0.4-0.5% for crystalline cells.
