How much solar radiation is reflected back
WebDec 5, 2024 · Whether solar panels reduce the amount of suns rays reflected back into space depends on their albedo and the albedo of the surface that they cover. Desert sand, for example, is fairly reflective and solar panels might reflect less sunlight back into space than deserts, but it's not just the reflection that matters.
