The best solar panels currently available are about 13% efficient in converting sunlight to electricity.

The best solar panels currently available are about 13% efficient in converting sunlight to electricity. A typical home will use about 40. kWh of electricity per day (1 kWh 1 kilowatt hour; 1 kW 1000 J/s). Assuming 8.0 hours of useful sunlight per day, calculate the minimum solar panel surface area necessary to provide all of a typical home’s electricity. (See Exercise 96 for the energy rate supplied by the sun.)
