Efficiency of using solar panels for consumed electricity cost reduction

Abstract

The purpose of the paper is to evaluate the efficiency of using solar power plants operated in parallel with the electric grid for the companies and enterprises of the Republic of Khakassia which being charged for electricity at the unregulated rate. The study involves the visual analysis of input data graphs, statistical and computer modeling using PVSYST software. The electricity consumption and electricity rates of the objects under consideration are analyzed. The use of solar power plants operated in parallel with the existing electric grid is justified. The block diagram of the solar power plant and its connection method are chosen. Investments in facilities are determined. Power plant payback periods are calculated. The use of solar power plants operating in parallel with the grid has the greatest effect for the enterprises and companies being charged for electricity by unregulated rates of the first price category. The use of parallel solar power plants is advisable without power delivery to the centralized electrical grid due to the complexity of this connection and low purchase prices for electricity.
