Designing a 1 MW photovoltaic farm and studying the effect of wind speed on its performance in the climatic conditions of Yazd province

The increasing use of the photovoltaiv sources and their low efficiency, makes it very important to study on different ways of anhancing their efficiency. In this paper, after designing a photovoltaic farm, the heat transfer equations in solar cells are investigated. Considering the effect of the wind speed on these equations, a solution is provided to decrease the temperature and then increase the efficiency of the photovoltaic panels. Therefore, by means of the meteorological data and three softwares (System advisor model, Matlab and Meteonorm), the 1 MW photovoltaic farm in climate condition of Yazd province is simulated. Then, the effect of wind speed on the efficiency of the photovoltaic farm is investigated. Results shows that with the increase of the wind speed up to 17 m/s, the output power of the farm is considerably increased. For the wind speed upper than 17 m/s, the output power increase is negligible.
