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.
