The system consents of 14PV panels, converter, and two-way electrical meter. Each board produces 240watts/hour as a maximum, and the total watts produces from the system is 3.5kW/h, this is in an ideal situation, when the sun is perpendicular to the panels. The electricity produced by this system was measured in a period of four years, and is approximately 24000kW. The annual average is 6000kW and monthly average is 500kw, which equals to 50% of total house consumption according to bills. With respect to cost, the PV cells have reduced the monthly bills to 1/6 in summer months, and to 1/3 in winter. The cost of the PV system at installation time 4 years ago was $6000, the payback period is calculated 5years. However, a similar PV system now costs less by one third of the installed system four years ago, i.e. $4000. This is because the government encourages insulation of PV systems in households and pays back one-third of the cost in cash money. Banks also provide zero interest loans to buy PV systems. Electricity generated from PV cells reduces electrical load on the main electrical board, and consequently the amount of oil burned in electricity generators and reduce air pollution.
