2015 International Conference on Circuit, Power and Computing Technologies [ICCPCT] 978-1-4799-7075-9/15/$31.00 ©2015 IEEE A Case study for Solarification project of Different places in India Ravi Kumar Dept of Electrical Engineering Indian School of Mines Dhanbad, India Dr. Nitai Pal Dept of Electrical Engineering Indian School of Mines Dhanbad, India AbishekNaithani Dept of Electrical Engineering Indian School of Mines Dhanbad, India Abstract—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. Keywords—economic analysis; stand-alone PV system; solar radiation level effect; RET screen; Solarification I. INTRODUCTION Today, many countries in the world are facing shortage of electricity including India. About 600 million household in India don’t have electricity available to their home. For ensuring supply of electricity to all, it is necessary to look beyond the conventional sources of energy like wind, solar, tidal etc. India has good solar irradiation as it lies between the Equator and Tropic of Cancer. Annually the average temperature of India ranges between 25°C to 28°C which is best condition for using the solar PV cell to generate electric energy. The importance of energy in development of country is considered as key factor. Recent studies shows that availability of energy is in direct proportion to the economic growth of the country [1]. According to IEA report, there is 53% increase in consumption of primary energy worldwide up to 2030 and 70% of above figure come from developing nation. Presently the fossil fuel provide 85-90% primary energy supply to world. The greenhouse gases emission due to incomplete combustion of fossil fuel are main cause behind climate change. According to WHO report 1.6 million people die due to climate change every year and this figure will be doubled by 2020 [2] .Although Renewable can’t replace fossil fuel completely but they can help to overcome the need of energy in the country. PV technology can be used in those places where there is no provision of grid electricity, and electricity required for water pump used by farmers, in telecommunication Industries (towers), highway telephone network, as a street lighting system, home lighting and many others. The performance and life cycle of PV system (panels) is mostly affected by values of solar irradiation falling on aperture area, azimuth angle and temperature. [3, 4]. In this paper PV system is analyzed at different climate condition of India to fulfil the domestic needs of energy. Fig.1 Global Horizontal Irradiance at various parts of India
