Solar panels work because photons from the sun give their energy to electronsin the panels. at noon on atypical mid-june day, the power of the visibleradiation from the sun is about 225 watts per square meter. if you had solar panels onyour roof covering an area of 2 meters by 6 meters, and the efficiency of the panel was13% (meaning that 13 out of every 100 photons hitting the panel sent an electron downthe wire), how many electrons per second would you get? (you can take the averageenergy of a solar photon to be that of green light, about 535 nm.)
