Expert Answer:

Dear student
 
Solar energy cannot be used to do the work directly, because it is too diffused and it is not always uniformly available. So devices like solar panels, solar cells have been invented to make use of solar energy.
solar panel consists of black-painted metal surface which absorbs the sun's energy and heat water in its contact. The heat can be used to produce steam by boiling water and steam is used to drive the turbine of a power generator and generate electricity which can be used for various purposes.
