heat from a fire heats our hands mostly by convection (and some radiation) because the heat produced directly heats the air above (for a lot of radiation to happen the nucleus of the atoms must be affected greatly as well). Whereas in solar panels, it is absorbing radiation, so naturally it will also reflect radiation (some convection takes place as well)
@adi - wow! ur rep is shooting up everyday. let me help u! +rep! :D
Clem:
Hey does anyone know why we get most of the heat by convection when we put our hands above a fire and solar pannels get most of the heat by radiation?
