...or better yet...
- hwillis 9y agoThese panels reject heat at a rate of up to 70 W/m^2. A good solar panel absorbs 20% of incoming light, which typically peaks at about 1000 W, so a solar panel reduces temperature by 3x as much. So... you could just do that.
- irrelative 9y agoFurthermore, air conditioning isn't lowering the temperature of a system by the energy consumed. Rather, it acts like a heat pump which usually pumps more energy that is used. So 200 J/s of electric power running a typical AC unit would likely reject more than 200 J/s from a building.
- paddy_m 9y agoCould you create a solar panel that generates energy during the day and rejects heat during the night? Would it be efficient at either task?
- the8472 9y agoSolar panel efficiency decreases with rising temperatures, so maybe increasing its emissivity in the infrared window could improve efficiency.
