In the recent years, photovoltaic (PV) power generation has been receiving considerable attention as one of the more promising renewable energy for the generation of electrical power. The reason in this rising lies in PV direct conversion of sunlight to electricity, the non-polluting nature of the conversion process, and PV’s independence of fossil and nuclear fuels. To date, the widespread of PV generation has been hampered by economic factors. Therefore, the low of conventional energy sources has obviated the development of a broad based PV technology at the present time. This paper discusses the modelling of 40KW PV standalone grid system useable for off grid application. It highlights the introduction of PV system, computation of number of panel, battery rating, charge controller, inverters and DC-AC converters. PV generation could be justified only for special situations, mostly for remote sites where utility lines or other conventional means of furnishing energy may be prohibitively expensive and almost impossible to deliver power from the grid.
