The off-grid solar photovoltaic system is one of the promising technologies for generating friendly electricity. Duhok city suffers from energy shortages in that electricity comes from local generators to support national grid. The aim of the research is to eliminate local generators due to their high costs and noise levels. A photovoltaic (PV) solar system type (off-grid) was proposed for one villa in AVRO city Duhok. A calculation has been done to select size of the system and A PV Syst software was adopted to investigate the design of the proposed system and additionally examined the economic analysis as well as the net profit. The proposed system is used with an average electricity demand of 12.9 kW/day. A typical 3.3 kW PV system was determined to be able to meet the daily power requirements of an entire villa with 8 panels: two in series and four in parallel where each panel has a rating of 415W. The system includes 8 batteries of 12 V,200Ah, and a 5-kW inverter with MPPT tracker. The result shows that yearly average of the energy requirement of villa is 4728.9 kWh and energy available through Solar’s panel is 5999 kWh/year
