1. Introduction
Energy requirement is increasing at an alarming rate and world is facing critical problems regarding energy deficiencies. Solution to this situation lies in shifting on dependencies of energy requirement from conventional energy sources to renewable energy sources. Solar energy, a clean and abundantly available renewable source of energy is seriously being researched as strong contender for future energy solutions. Photovoltaic (PV) system is noiseless, free of moving parts having less maintenance and operational costs and can be produced near load centers, hence can be efficiently utilized and integrated in power systems.
