Determination of photovoltaic panel performance ratio value dependent on external temperature and solar radiation for Turkey

In this study as a deficiency in the literature located hourly rate for the overall performance of the panels Turkey, the determination is made on a monthly and annual basis. On the whole panel surface temperature of the last thirty-five years starting in Turkey radiation value it was calculated in detail. Panel surface temperature of the provinces determined by determining the performance rates of the panel has been turned into map. After all these calculated values, electricity generation from PV module outputs has been calculated separately for all provinces. Panel performance probability distributions for 81 provinces in Turkey are provided are identified. Thanks to these distributions, it is easy to determine which values of the panel performance ratio can be changed in any province. With these values, it can be determined which values can be obtained for the best and the worst situation.
