The article is devoted to the study of various ground configurations for the placement of photovoltaic panels in order to increase the electrical energy efficiency of micro- and low-power solar power plants through field studies. In the course of the research, statistical methods for processing experimental data were used. Field studies were carried out during the summer period of 2022 in the central part of Yakutia. It was found that in the case of the use of “L” and “C”-shaped configurations for placing photovoltaic panels and a tracker installation, electricity generation increases by 4.8%, 33.9% and 59.2% when compared with the stationary placement of a photovoltaic panel on a carrier structures to the south. In this regard, it is recommended to use the “C”-shaped configuration of the placement of photovoltaic panels instead of expensive tracker installations in micro- and small-scale solar power plants.

This article presents the results of research aimed at studying and analyzing the influence of the sharply continental climate of the Republic of Sakha (Yakutia) on the electric power parameters of a polycrystalline solar panel. The results of experimental studies are shown in the form of graphical interpretations and patterns of current and voltage strength from external parameters in winter, such as: time, luminous flux, temperature and weather type. At the moment, in accordance with the requirements of the Paris Climate Agreement, the introduction of renewable energy sources into the electric power systems of the countries is one of the priorities. On the territory of the northern part of the Republic of Sakha (Yakutia), about 24 solar power plants are operated, but it is important to note that these facilities practically do not function in winter due to low solar activity.

The article is devoted to the study of the features of the operation of a photovoltaic installation at low temperatures in the North-Eastern part of Russia. The introduction of solar power facilities in hybrid opera-tion with facilities of traditional energy sources in the territory of the North-Eastern part of Russia is one of the possible solutions to achieve costly fuel savings in power generation facilities. The electric power regularities and methods of processing experimental data in the MatLab environment are applied and the stages of field research in the field of solar energy are described. The indicators of the influence of extremely low ambient temperatures on the operating parameters of a photovoltaic installation have been obtained.
