Upazilla Health Complex (UHC) offers the primary level health care facilities for rural communities. Every day thousands of patients come here for health care. The Health complex needs 24 hours electric supply. The national Grid cannot provide continuous electricity supply. Rural areas face various disturbance such as load shedding, blackouts problems and bad weather situation. In this paper, we report on the techno-economic assessment of net metering based On-grid photovoltaic system for Kaunia Upazila Health Complex in Rangpur District, Bangladesh. The analysis is based on the grid-connected photovoltaic system without battery storage. The HOMER software is used to obtain the overall analysis and the load study is carried out by HOMER powering tools. It suggests that the selected health complex requires a 34 kW PV system. The system’s net present cost (NPC) and the levelized cost of energy (COE) are $35,524 and $0.048 respectively. In this proposed system, renewable energy provides 99% of the total power requirements, while the generator and grid provide only 1%. The system produces 53,736 kWh a year of electricity where the system’s surplus electricity is 3226 kWh per year which can be sold to the national grid using a net-metering system.
