A case study for solarification project of different places in India

As the population is increasing day by day, so the energy demands are bound to increase. In recent years India has seen several blackouts. To meet the future demand of power we should start investing in renewable energy. India has great potential for solar energy which is still untapped. Solar energy is residential friendly and can be installed easily in residential areas. This paper presents the Modeling and Cost analysis of solar photovoltaic (PV) systems and the energy saved in a domestic household from its use. The study is conducted in five different places of INDIA using RETSCREEN software. The role of solar radiation on size of PV system and their economic influence of different location is analyzed for equal load demand. The parameters used for economic analysis of modeling work are Net Present value (NPV), payback period, Internal Rate of Return (IRR) etc. Different parameters were compared for different selected locations. Finally, it is found in the analysis that solar irradiation level has great influence on the PV array size, its efficiency, capital cost, IRR, payback period and levelised cost of energy, etc. Also electricity generated by the solar PV system reduces greenhouse gas (GHG) emission and makes the environment more eco friendly. The weather information was taken from the NASA website.
