Solar radiation that is absorbed by a solar panel will either heat the panel or generate electricity, which will also mostly become heat in the end. Reflected radiation will hopefully leave the earth.
The things that cool the planet are mostly white — reflective. Clouds, white roofs, etc.
Trees cool their local area by performing endothermic reactions creating carbohydrates and lignans.

- Filligree 6y agoA fair bit. I don't have numbers for trees in particular, but one of the benefits of putting solar panels above farms is supposed to be cooler panels, which improves panel efficiency. Though most of that would be evaporation, not chemistry.
