Solar energy is one of the most renewable and easily accessible sources of energy.
Modern solar panels are simple and reliable in operation. They do not require additional resources, are not prone to mechanical wear and do not require maintenance. The definition of characteristics, the study of changes in the process of operation in the presence of environmental influences, changes in the parameters of the electrical network is an urgent problem that will be considered not only today but also tomorrow. Because knowledge of these values will allow the manufacturer to predict, control and edit the technical parameters at the stage of production of solar cells.
The model of a solar battery with a power of 270 W is presented in the form of a functional scheme. The polynomial dependence of the maximum power of an alternative energy source from solar radiation is proposed. This model was obtained by approximating the curves constructed on the basis of modeling in the Matlab program. The objective function of the mathematical model is represented by a second-order polynomial. The coefficients of this polynomial are determined for different
operating temperatures. A simplified flowchart for calculation of mathematical dependence is presented. The given block diagram gives the user the opportunity to navigate in the stages of choosing technical parameters, modeling and obtaining adequate results. The approximation error does not exceed 1% in the range of operating temperatures from -20 to 25 ºС. In the region near absolute
zero there is a slight increase, which indicates a greater complex dependence, which is better characterized by polynomials of higher orders. The proposed model for determining the electrical parameters of a solar battery is adequate, which is confirmed by calculations.
