To a point, because 100%-efficient panels don't exist. If they did, then my naive understanding is that they wouldn't get hot.

- starbase 5y agoPerfectly black and doesn't get hot in the sun. I love it.
- baq 5y agoagain, thermodynamics: > The maximum theoretical efficiency calculated is 86.8% for a stack of an infinite number of cells, using the incoming concentrated sunlight radiation. When the incoming radiation comes only from an area of the sky the size of the sun, the efficiency limit drops to 68.7%. https://en.wikipedia.org/wiki/Solar_cell_efficiency#Thermodynamic_efficiency_limit_and_infinite-stack_limit https://en.wikipedia.org/wiki/Solar_cell_efficiency#Thermody...
- frosted-flakes 5y agoThat's why I said that 100% efficient panels don't exist.
