Abstract
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 need 24 hours electric supply. Because of many operations such as maternity facilities, Obstetric Delivery, operation theatre and various electric instruments need to electricity supply. Sometimes the power supply of National Grid cannot provide continuous 24 hour electricity supply. Because of various disturbance such as load shedding, blackouts and bad weather situation. If continuous power supply cannot possible the patient face various serious condition. For this reason, continuous electric power supply this is the ultimate solution. . In this paper, we reports on the techno-economic assessment of net metering based on-grid photovoltaic system for an Upazila health complex in Bangladesh. The analysis is based on the grid-connected photovoltaic system without battery storage. The Homer pro software is used to obtain the overall analysis and the load study carried out by Homer powering tools is online software. 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 percent of the total power requirements, while the generator and grid provide only 1 percent. The system produces 53,736 kWh a year of electricity whereas the system’s surplus electricity is 3,226 kWh per year and this is sold to the national grid using a net metering system.
