The PV solar system on the rooftop of buildings is a good source of renewable electric energy. India has very large number of educational institutions with large non-invested rooftop with shortage of electrical energy supply. The present work aims to undertake a techno-economic feasibility assessment of a grid connected 100kWp capacity solar PV system proposed to be installed on the rooftop of an educational institution in Sirsa (India). RETScreen software was used to design and simulate the proposed system in order to analyse the technical, economic and environmental implications of the system. Findings show that, there is a high potential for electricity generation in most months of the year. Considering electricity export rate of Rs 4 per kWh, 70 % debt on initial investment, debt term, inflation rate and other parameters the equity payback period (PBP) estimated to 6 years, net present value (NPV) of the project becomes positive in the 6th year and internal rate of return (IRR) is found more than the discount rate. All these economic indicators show that the project is economically feasible. Moreover, the system has a low levelized cost of electricity (LCOE) as compared to the existing grid tariff, the study adds significantly to the national objective to reduce its dependency on fossil fuels while meeting local energy requirement
