A photovoltaic system is installed, since 5 years in a medium size house in Amman city, Jordan to support the electrical system of the house. The system consents from 14 boards, converter, and two-way electrical meter. Each board is producing 240 watts/hour as a maximum, and the total watts produces from the system is 3.5 kW/h, this is in an ideal situation, when the sun is perpendicular to the system. The total kW produced from the system in 4 years is approximately 24,000, with an average of 6,000 kW/annual; and 500 kw/month, which is equal to 50% of the total house consumption. With respect to cost, it reduces the monthly bills to 1/6 of the monthly cost in summer, and 1/3 of the monthly cost in winter. The total cost of the system at installation time, 4 years ago, is $6,000, and accordingly the system rewards, its cost in 5 years. The cost of the system now is one-third of the previous cost; and the government is encouraging householder to support their homes by photovoltaic system by giving them one-third of the cost as cash money. Jordanian banks are now accepting monthly payment of the system without additional cost. This system does not only reduce the electrical load from the main electrical board, but also reduces the government oil bill, as Jordan is a poor country with respect to oil and other resources, but is also helping to reduce the pollution caused by burning conventional oil.

The thermal and electrical efficiency of a custom-designed PV/T panel cooled by forced air circulation was investigated by experimental and computational fluid dynamics (CFD) analysis. Experiments were carried out with four different array configurations, under constant irradiation of 1100 W/m2 and 3 different air velocities (3.3 m/s, 3.9 m/s, and 4.5 m/s). The heat transfer surface area and forced air circulation are known to positively affect the total heat transfer, and therefore, it is foreseeable that an increased number of fins and higher air velocities will help maintain the electrical efficiency of the panel at higher levels. The main objective of this study is to determine the critical threshold for the abovementioned parameters as well as to show how important parameters, such as fin arrangement and consequent turbulent air flows, are for satisfying the heat removal needs. Highest efficiency was achieved with a 108 pc type 1 arrangement at 12.02% as expected. Nevertheless, while the 108 pc type 2 arrangement could maintain the electrical efficiency at 11.81%, a close level of 11.55% could be obtained with a 54 pc type 2 arrangement. Experimental results are compared with ANSYS Fluent program, and the effect of the number and arrangement of the fins on the efficiency of the panel has been shown.
