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.

The efficiency of electric power systems in cold climatic zones is determined by a variety of factors, including low temperatures, high equipment wear and tear, and increased load on electrical networks. This article aims to identify ways to improve the energy efficiency of electric systems operating in cold winters and frosty conditions, as well as to explore methods that can reduce costs and improve the reliability of electrical networks. The approaches discussed in this article can help minimize energy losses, extend the lifespan of electrical equipment, and reduce the overall operating costs of energy sector enterprises.
