Depends. Some solar panels, like the ones in those spinning toys, are actually powered by the impact of photons on the panels.
The ones that generate electricity are made with silicon and phosphorus, which have a negative charge (one extra electron). When the photon hits the silicon/phosphorus molecule, the extra electron is given a boost out of the electron shell and becomes available. So if you hook up a circuit, off it goes. It goes to another part of the circuit, where silicon is bound to boron, which has holes in its electron shell.

thats a real good question never thought about it before, but I would guess all the electromagnetism, like the gamma rays and uv rays etc… it gives off, but thats just a guess
