Abstract
When considering the operation of the solar panel and performing modeling of its operation in [1], such input parameters as the level of solar insolation (the amount of light coming to the SP) and the value of the outside temperature on the solar panels themselves were taken into account. However, such an important parameter as the angle of inclination of the solar panels was not taken into account in such modeling. The value of this parameter takes into account, of course, the level of solar insolation, because the level of light that enters the JV directly depends on the angle at which they are located. However, it has not been considered that sensors (or luxmeters) for measuring illumination may be located at an angle other than the angle of inclination of the solar panel or, more importantly, the solar panels themselves due to their design features may not receive enough solar radiation. can take into account light sensors. This possibility exists at an angle of inclination close to zero, ie at dawn and sunset. This article is designed to take into account the influence of the angle of inclination of solar panels through the use of empirical dependencies and to test the theoretical foundations that have been formed in previous articles [1-4]. This article demonstrates the practical significance of taking into account the value of the angle of inclination of solar panels in the calculations of the photovoltaic plant. To do this, we first analyzed the state of the issue and the available methods of changing the angle of inclination in the operation of the electrical network with photovoltaic panels. Secondly, the influence of the geometric arrangement of the panels was taken into account when constructing the mathematical model. Studies have concluded that the optimal method of controlling the angle of inclination of photovoltaic panels is its seasonal change. After all, the application of this method increases the power output of RES with an average of 35% in summer and 10% in winter compared to fixed panels and does not require additional and sometimes very expensive equipment compared to the dynamic change of angle during the day. Further use of the proposed method will bring the values obtained during the simulation to the practical ones obtained when working with the installation.
