Efficiency of solar panels application in conditions of Leningrad region

Abstract

Introduction. Comfort in private homes remains a constant reason why more and more people prefer permanent residence in the suburbs. Energy supply and savings are becoming one of the most important reasons for turning to alternative energy sources. One of these is the use of solar panels and installations. In this paper, the efficiency of using such a method of energy supply at home is considered, the calculation of the cost and payback in the Leningrad region is given. Materials and methods. The methods of measurements on the object and mathematical methods of estimation were used. Results. Autonomous power supply of the house is possible only in the period from March to September, in January, February, October, November and December it is necessary to resort to using additional equipment as a generator. Conclusions. According to the results of the study, the installation of an autonomous system for providing a low-rise construction facility with electricity on solar cells has a very long payback period when located in the Leningrad region, while an economic assessment shows that it is advisable to add up the funds spent on the installation for a long-term period rather than paying for electricity every month. Such a solution can be effective in conditions where there is no alternative to energy sources or being at a distance from a common power line, since the costs of laying the power grid will be similar to this installation without taking into account the cost of paying for electricity according to the tariff.
