How do solar panels absorb sunlight
WebJan 20, 2024 · The solar panels absorb around 30% of the heat energy from the sun, re-emitting half towards the sky and the other half to the roof, which then absorbs back 30% of the heat that the solar panels emit, giving a total absorption of 5% of the heat of the sun. To recap, that is 30% of 50% of 30%. There is a study by the UCSD that supports this concept.
