The article is devoted to determining the influence of low and high ambient temperatures on the functioning of a photovoltaic installation with graphical interpretations and regularities. A method for determining the electric power efficiency of a photovoltaic installation is applied for a wide range of ambient temperatures with graphical interpretations. Regularities for determining the average statistical indicators of the decrease and increase in the electric power efficiency of a photovoltaic are used. The control parameters of the change in the value of the generating power of a photovoltaic installation in the temperature range from -60 0С to +60 0С are obtained, which can be used in modeling operational processes and engineering calculations of the operating modes of solar power plants.
