Abstract: Renewable energy is a viable alternative to meet growing energy demand of the country. Realizing this fact, Indian government has recently expressed an intention towards achieving 100GW of solar capacity by 2022; out of which 40% is being expected through decentralized and roof top scale solar projects. One such Photovoltaic (PV) plant of 50kW capacity installed at the roof top of Saraswati library building of Deenbandhu Chhotu Ram University of Science & Technology has been analyzed for its technical and financial viability. We have also analyzed the mix of technicalities involved in this PV plant. This PV plant is generating more than 5200kWh/month of electricity and reducing 4070kg/month of GHG emissions. Further, this plant is installed with govt. subsidy and found that the subsidy amount makes it lucrative by reducing pay back duration to 5.7 years and increasing the IRR to 16.97%. But even without subsidy, the pay back duration comes out to be 10.3 years and IRR equals to 8.22% to make it financially viable. Thus it is observe that if govt continued to provide subsidy up to 30% to such projects for next 2 to 3 years, then it will help to attract the domestic sector to get install more and more PV plant on their rooftop. Further attempt have been made to present a generic framework for providing SPV power system.
