Solar energy is an alternative energy method which is produced by collecting sunlight and converting it into electricity. Solar energy uses solar panels to collect the rays and they are large, flat panels made up of individual solar cells.

The benefit of using solar energy to generate electricity and heat is that it does not produce air or water pollution or greenhouse gases.
