You are designing a solar panel cover to protect rooftop solar panels from beingdamaged by debris.  At some point during the day, the panels form a 60-degree angle relative to the sun’s rays. The panels are 3m x 1m wide. a) What property of incident radiation do you want to maximize to allow the maximize amount of light to hit the panels below your cover? b) If the absorptivity is 0.2 and the reflectivity is 0.1, what percentage of the radiation reaches the solar panels? c) If the irradiation, G, is 220 W/m2, how much power passes into the solar panels below the cover?
