RESEARCH OF MODELS OF EFFICIENCY OF ENERGY PRODUCTION BY SOLAR PHOTOELEMENTS IN THE LANGUAGES OF ADAPTIVE POSITIONING

Abstract

The paper considers one of the problems of solar power plants, namely, a decrease in the volume of energy generation due to a change in the angle of incidence of the sun's rays. The larger the angle, the less power generation. To increase the amount of energy produced, tracking systems of solar stations are used. Due to the positioning mechanisms of photocells relative to the position of the sun in the sky, it is possible to maintain a fixed angle of incidence of sunlight on the panel. This positioning allows you to maintain maximum power generation during daylight hours.

To compare positioning methods, a study was made of power generation by simulating panel operation under different conditions. Three main models have been formed: solar panels without adaptive positioning, solar panels with uniaxial positioning, and solar panels with biaxial positioning. To evaluate the effectiveness of each method, criteria were selected for comparison: the amount of energy generated and the energy consumption of the adaptive positioning system.

The resulting models took into account the costs of maintaining adaptive positioning systems. As a result, when using panels with single axis positioning, energy production increases by 22.1% during the year. If a two-axis adaptive positioning system is used, then the increase in energy production will be 24.2% compared to a single-axis positioning system.

The model data were compared for each month of the year. During the summer months, the energy yield of solar panels with dual axis positioning is reduced relative to other solar panel positioning methods. The reason is the increase in temperature from direct sunlight, which reduces the efficiency of work. But in other months of the year, the biaxial positioning system performs better, which offsets the performance in the summer. Especially in winter, when a lot of energy is spent on heating.
