At a certain location, the solar power per unit area reaching the Earth's surface is 180 W/m2 averaged over a 24-hour day. Suppose you live in a solar powered house whose average power requirement is 3.2 kW.
At what rate must solar energy reach your solar panels if your solar panels have a typical coversion efficiency of 14 %. (In other words, what power must your solar panels receive?) Answer in both kiloWatts and Watts.
