How practical is solar power for various devices? Assume that on asunny day, sunlight has an intensity of 1000 W/m2 at thesurface of Earth and that, when illuminated by that sunlight, asolar panel can convert 10% of the sunlight's energy into electricpower. For each device given below, calculate the area A of solarpanel needed to power it. (a) A calculator consumes 50 mW. Find A in cm2. Is A small enough so thatthe solar panel can be mounted directly on the calculator that itis powering? (b) A hair dryer consumes 1500 W. find A inm2. Assuming no other electronic devices are operatingwithin a house at the same time, is A small enough so thatthe hair dyer can be powered by a solar panel mounted on thehouse's roof? (c) a car requires 20 hp for highway driving atconstant velocity (this car would perform poorly in situationsrequiring acceleration). Find A in m2. IsA small enough so that this solar panel can be mounteddirectly on the car and power it in "real time"?
