Stand-Alone Solar Photovoltaic Power Generation System

Increasing demand for electrical energy as well as environmental concerns related to fossil fuel usage are the driving forces behind the development of new energy sources, which are renewable and ecologically safe. The energy sources, which include energy from wind, water and biomass, geothermal and solar energy are renewable and environmentally friendly. Among these clean energy sources, solar energy is one of the most promising and fastest growing renewable energy sources worldwide. Solar energy is freely available and it is very clean source of energy. Solar energy can be converted into electrical energy by using different method. Out of them conversion of solar energy into electrical energy by using solar PV panel is possible at many places such as open ground or roof-top of home, office, etc. The main objective of this paper is to study design of solar photovoltaic stand-alone power generating system. In this paper, system of solar power generation is explained. The system consists of solar panels, DC-DC converter, and charge controller, inverter and battery storage. Also, solar PV system can be designed according to the requirement of the load.
