Technical and economic aspect of solar power plants use in power supply systems for agricultural production and household in the conditions of Siberia

In the Siberian Federal District (SFD) there are a number of rural settlements remote from the central power supply system, in which an autonomous power supply is provided from diesel power plants (DPP). In recent years, due to the physical and obsolescence of diesel generators (DGs) that are part of DPPs, there have been trends to replace DPPs with autonomous hybrid power plants (AHPPs) - solar power plants associated with DGs. The «Hevel» group of companies (Novocheboksarsk, Russia) has launched mass production of solar modules (SM) and other electrical equipment for solar power plants (SPP), which meets modern world developments. In addition, in connection with the creation by the state of a favorable investment climate for the widespread introduction of these developments, mass construction of SPP and AHPP in the Siberian Federal District began. The most massive construction of solar power plants and AHPP«Hevel» was carried out in the republics of Altai and Tuva. Such experience is available in the Krasnoyarsk Region, the Republic of Khakassia. The purpose of research is to study the technical and economic aspect of the use of solar energy in the power supply systems of agricultural production and life in Siberia for the rational implementation of SPP and AHPP. To achieve the goal, it was necessary to solve the following tasks: to study the parameters of SPP and AHPP for the conditions of Siberia; conduct a technical and economic comparison of the cost of electricity received from SPP and AHPP and tariffs for electricity for the population living in rural areas with tariffs for agricultural producers (peasant farms) in Siberia, as well as give recommendations on the rational use of SPP and AHPP in the conditions of Siberia. The authors of the paper gave a technical and economic assessment of the generation of electricity by a SPP with a capacity of 15 kW, offered by «Hevel» to household consumers, or peasant farms, taking into account the receipt of solar radiation on the surface of the SMs that are part of the SPP, taking into account the location of the SPP and DPP of the same power in 11 rural settlements of the Siberian Federal District.
