Optimal design of photovoltaic power system for a residential load

In most developing countries, for the proper utilization of solar energy the system designed should be optimized. This paper presents the design and analysis of photovoltaic (PV) system to supply electricity. A stand-alone optimization simulation model is developed using the HOMER software. The radiation data for Baru Sahib, H.P. is collected for the every month of the year. Simulation model is used to find the best system model based on particular load. The optimization results shows that a PV array of capacity 6 Kw produces 14,080 Kwh/yr. Results shows that the Net present Cost (NPC) is 76,307 US$, levelized cost of energy 1.211/kwh and operating cost is 5,067/year.
