The effect of ambient temperature on the yield of a 3 MWp PV plant installed in Ecuador

Abstract:

The integration of photovoltaic power plants in the distribution or transmission level is already a reality. Usually, the location chosen for these power plants consider high solar irradiance, but the temperature could be a drawback. Thus, the aim of this paper is to show the effect of solar irradiance and ambient temperature on the power generation of a photovoltaic power plant. For this, a real photovoltaic power plant is chosen in the Ecuadorian line in South America. The results show that the active power is reduced around 0.1 to 0.3 p.u when the ambient temperature is higher than 25 Celsius degrees although the solar irradiance is high.
