【 摘 要 】

In this paper, performance analysis of stand-alone photovoltaic (SAPV) system for Primary Health Centre in Orlu, Imo state was conducted. The USAID categorisation of health clinics is used to identify the Primary Health Centre  as Category I Health Clinic with corresponding daily and yearly energy demand of approximately 11500 Wh/day and 4197.5 KWh/year respectively.  PVsyst software solution was used to model and simulate the entire PV system. 22-year air temperature and monthly and annual averaged insolation incident on a horizontal surface obtained from National Aeronautics and Space Administration (NASA) online meteorological portal was used. The results showed that the SAPV system has yearly energy output of 5269Kwh/year with performance ratio of 58.4%, effective operating or nominal efficiency of  8.83%, loss of load probability of 7.1% and unit cost of energy of 81.5 Naira per KWh. The SAPV is designed to be affordable for the Primary Health Centre in Orlu, Imo State, Nigeria.
