Nowadays the demand of electrical energy is increasing because human are suffering from energy crisis. Because the renewable resources are limited and are responsible for the depletion of our environment. To meet the demand and to decreases the air pollutants human must find the new solutions to tackle with this problem. And finally they find the solution by using non renewable energy sources like wind, solar and so on. Among all the renewable energy sources the most popular source is solar energy.Energy is an important global issue as currently most of the energy comes from fossil fuels. If fossil fuel resources will continue to be consumed at the current rate it will be completely dissolved in 100-150 years. Furthermore, its consumption raises serious environmental concerns as this increases carbon dioxide (CO2) and greenhouse gases in the atmosphere. A possible solution to this problem is to utilize renewable energy resources. Among all the renewable energy sources, solar power is the one of most promising and free of operational cost energy source.
