Assuming that solar energy is used to charge a storage battery which then in turn is to power a lamp of 40W. Solar cell obtains power at the rate of 100milliwatts per square centimeter, and the sunlight time is 12 hours. Determine the size of the solar cell that is need to power the lamp for a duration of one hour.(Assuming the battery power will be used afterwards)
