ELI5: Why are solar panels only like ~20% efficient (i know
First, the solar panel has to send out light as well: the temperature of the panel is above absolute zero, so it emits heat. This brings it down to 86.8%. But that assumes that the incoming light comes from every direction at once. In practice, the sun only covers a small part of the sky, bringing it even further down to 68.7%. Unless there
