These 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.

So 200 J/s of electric power running a typical AC unit would likely reject more than 200 J/s from a building.
