Energy demand is growing at a rapid rate due to urbanization and industrial growth. The main sources of energy i.e., conventional fuels are limited in reserve and depleting at an alarming rate. To fulfill the future energy demand, investigation of alternative energy sources either self-sufficient or supplementary to the main source is mandatory [1][2]. Among various renewable sources of energy solar, wind, geothermal, hydro are some of them. Solar energy as a source of electricity using photovoltaic (PV) conversion system has been growing at a faster rate in the last decades because of abundant availability of light energy; the PV energy is clean, noise free, offers long-term service with minimum maintenance, it can be generated at consumer area and also reduces transmission cost/loss [3]-[7].
