Abstract—The results obtained in the field of analysis and development of controllers for the charge of a solar power plant are presented. A description of the charge controllers of the solar panel (SP) is given and a scheme of a solar installation with their use is proposed. The maximum power point (MPP) of a polycrystalline silicon solar battery (SB) was calculated. The Pascal software for the research and analysis of charge controllers, which can be used for various types of SPs, including perovskite panels, is proposed. It is shown that the type of controller which tracks the MPP has better characteristics as it provides a higher charge. DOI: 10.1134/S1064226920080057
INTRODUCTION Currently, particular attention is being paid to renewable energy sources, which is related to a shortage of traditional resources and environmental problems. Systems converting solar energy into electrical energy are widely used1. Most well-known manufacturers in the field of renewable energy are developing their own solar industry. The creation and manufacture of systems for converting solar energy into electricity seems to be a promising and dynamically developing area creating environmentally friendly energy sources. In 2016, about 364 GW of solar energy was generated2. The world’s solar power capacities are increasing at the average rate of over 50% per annum in the 21st century. Neither financial crises nor sudden fluctuations in the cost of other energy resources have materially affected these rates. Despite the fact that the percentage of solar energy in the global energyconsuming network is not too large, leading experts suggest that in 30–40 years it will be the main source of energy on the planet3. Currently, most of the world’s population lives in areas where there is still a shortage of electricity. Thus, renewable energy sources, which include solar power plants, are the best option for domestic use. 1 The

The advantage of solar energy conversion systems lies in their minimal maintenance and environmental friendliness. The disadvantages of such systems include their relatively high cost and low efficiency [1]. However, the efficiency of such systems can be improved by using an efficient solar charge controller. The aim of this study is to analyze and develop controllers for charging a solar power plant. 1. EXPERIMENTAL AN
