Techno-economic analysis and environmental impact assessment of 3 MW photovoltaic power plant in Bangladesh: a case study based on real data.

Photovoltaic-based power generation is increasing in Bangladesh. With the high level of availability and being cost-effective in contrast with off-gird plants, grid-connected solar photovoltaic plants are growing popularity. The present research analyses the techno-economic and environmental feasibility of a 3 MW grid-connected PV plant in Ishwardi of Pabna district, Bangladesh, where 2 cases have been considered as 50% and 80% loan financing. With 50% loan financing, the NPV, IRR and PBP were found to be USD 1,849,450, 14% and 7.03 years, respectively. The cost of electricity by on-grid solar system was found to be USD 0.06285/kWh in case of 50% loan financing. In the case of 80% loan financing showed the NPV, IRR and PBP results to be USD 1,098,086, 10% and 10.37 years, respectively. In the 20 years of life cycle, the PV plant can generate about 83,933 MWh electricity that can reduce about 54,791 tons of CO₂, 573.3 tons of SO_2, 144.7 tons of NO_x and 28.6 tons of CO generations compared to the current generation mix in Bangladesh.
