Solar Overview 
 For Electric Customers
Solar energy is capturing sunlight to generate electricity. By placing solar cells, also known as photovoltaic cells, under direct sunlight, a direct current is established. The direct current is then changed to alternating current, suitable for use in the electric power system.
