Around 70 percent. When light hits a solar panel, it is photons (the individual packets of light) which do the work. Material in a Solar panel is designed to be receptive to photon energy, so that when a photon hits an atom in the solar panel, it knocks an electron loose which provides energy. However, photons have a variety of wavelengths, much like your radio dial has a variety of stations. If the wavelength is too high or too low, the can pass through the collector or hit another surface, thus creating heat.
