Now-a-days every country is looking for the alternate energy sources which reduces the usage of fossil fuels, natural gases, coal etc. The alternate energy sources are freely available energy that produced from the nature. Every country is looking for go green and clean energy implementation that reduces the usage of fossil fuels that naturally available from the earth crust. This paper talks about the feasibility analysis of a 100MW of photovoltaic power plant at Churu city, Rajasthan by using RET Screen. The RET Screen software is a software which is used for feasibility analysis, benchmark analysis, financial and emission analysis. This software is used to study the different types of Renewable energy’s like geothermal energy, bioenergy, solar energy, wind energy, etc. In this project we done a feasibility analysis of photovoltaic cells which converts the solar power into useful Power. The solar energy is the most abundant energy. So in this project we study the feasibility analysis of a solar or photovoltaic power plant which gives us the positive results. Hence, this project is feasible, financial environmentally eco-friendly which reduces the GHGS emissions and helps the country to achieve the clean energy nation.
