Abstract: The article is devoted to optimizing the use of solar panels for UAV power supply. The efficiency of the process of converting solar energy into electricity depends on two factors: the efficiency of the process of physical conversion of the optical rays of the Sun into electricity and compliance with angular ratios to ensure that direct sunlight enters the solar cells at right angles. The solutions of technological problems for the first factor are closely related to such indicators as ambient temperature, radiation spectrum, and the strength of the optical radiation flux. The second factor is the non-orientation of photodiodes of solar panels in relation to direct sunlight. The issue of optimizing the orientation of the optical axis of solar panel solar cells relative to the direction of direct sunlight, depending on the optical air mass, is formulated. To solve the optimization problem, the neoclassical Lagrange variational problem is applied, according to the solution of which, with an increase in the optical air mass, the angle difference between the directivity of the panel's solar cells and the directivity of direct solar rays passing through zero can change its polarity. The results of solving the optimization problem allow us to calculate the analytical dependence of the change in the value of the specified difference angle depending on the optical air mass.
