Local heating makes sense. Solar panels are mostly black to absorb energy rather than reflect it.

Mere mortal, they won’t keep you warm at night, and they won’t warm you during the day, either. In fact, every photon that your clever device turns into an electron-hole pair, is a photon that does not get degraded into infrared heat, at least not until you run it six hundred miles into a light bulb or something.
