Design and Economic Analysis of Solar Photovoltaic Power Plant for Gafargaon Govt. College.

Abstract

Solar power technology was present in Bangladesh from very long time. But due its high purchase cost only few were able to reap its benefits where coal based thermal power energy can not reached in Rural area. In previous years solar equipment was very costly and less efficiency but now a days due to the increase in efficiency of solar module and price drop of solar equipment. Govt. also takes a step to reach solar photovoltaic energy in rural area. In this paper, we carried out design, economic cost analysis of solar power plant for Gafargaon Govt. college, Mymensingh. This paper has two final result one is power plant design and another is its cost analysis. At first we find out the total energy demand for the college and that is 111.28 KWh. According to this energy demand we proposed PV power plan. We have used PV GIS software to calculation solar irradiation data and find out 4.78/day & solar energy production 344KWh/day. For proposed plant is required 556.2𝑚2 land area 124 modules, 40KW Inverter size. Total cost of the power plant is 11946810tk and per unit energy cost is 7.6tk with power plant life time warranty 25 years. It’s don’t need fossil fuels to generate solar energy as the result reduction in C𝑜2from the environment so, we choose solar energy for Govt. college as secondary energy source.
