These have been used as a ready source of energy whereby solar energy is converted to electric energy. They provide electric energy which is suitable to power up household appliances and other appliances which need electricity. The solar panels diver in their voltage output depending on the types of panels that have been used. This source of energy has been used as back up when there has been power failure from main source of electric energy and the technique that is used is that it stores all its energy onto a battery by charging it. During the day it will be using solar energy to charge the cells and at night it will no longer be using solar energy but its energy that has been charged in the cell.

The solar panels do no necessary need the sun as the only means of energy supply some of the panels have been made with a high material which responds to any type of light. Even at night these panels still provide energy as long as there is visible light such as the star and the moon. Great research is being done and some have invented solar cars. Maybe in the next generation we will now be using these panels for our everyday source of energy.
