Özet

Renewable energy utilization has been increasing at the same rate of the increasing the consumption of energy in all countries. The best use of the available energy and the search for different energy sources have been an important field of study all around the world after highly increasing of energy demand. Hence, today, generating energy from solar cells also called photovoltaics (PV) has become essential field of renewable energy. This energy source is also one of the fastest growing technology, converting direct sunlight to electricity. In this article, optimum tilt angles were examined by changing monthly, seasonal, and annually, which were obtained from PV panels installed in Bursa city of Turkey. It was found that the solar radiation increased by 22.21% for monthly, 21.17% for seasonal, and 16.44% for yearly. So, it was necessary to vary the tilt angle of the PV panels at least seasonal (four times a year). In addition, the cooling effect of the wind on the cell temperatures, electrical energy generation, and energy efficiency of the different mounted PV panels with the optimum tilt angle on a monthly basis was theoretically examined. Consequently, the wind cooling was shown to be very effective on cell temperatures and energy efficiency under wind cooling effect was more than 4.8% during a year. Another finding of this study was that the energy efficiency and generated electrical energies of free standing PV panels were higher than sloped-roof PV panels.
