Abstract
The performance analysis for 100kWp grid-tied solar PV power plant installed at Chhauni Complex, Nepal Telecom, Kathmandu was performed. The technical and economic performance parameters were calculated from the data collected in the data logger of the inverters. The simulations of the system for installed capacity with three different scenarios were done in the PVsyst tool. The irradiance data obtained from the Department of Hydrology and Meteorology was used for simulation. The technical performance parameters for all the cases of simulations were compared. The economic analysis comparison between best scenario and actual case was done. The technical performance parameters like Energy generation, Final yield, Reference yield, Performance ratio, capacity utilization factor, overall system efficiency for the actual case were found to be 9.75MWh/month or 325kWh/day, 3.2kWh/kW/day, 4.5kWh/m2/day, 72%, 13.4%, 13.6% respectively. The system saves the energy bill to the owner of plant annually by NRs. 1.3 million. The economic performance parameters like NPV, IRR, LCOE and DPBP were found to be NRs.3.39 million, 17%, NRs. 7.92/kWh and 8.2 years respectively. Thus, the roof-top grid-tied solar PV power plant can be better for utility energy bill saving, own energy generation plant
