Solar Cells’ Characteristics of Unmanned Aerial Vehicle Under the Coupling Influence of Flight and Environmental Factors

Abstract

This paper investigates the power generation characteristics of solar cells mounted on unmanned aerial vehicles (UAVs) under the coupled influence of flight conditions and the surrounding environment. Firstly, the study reveals that the voltage, current, and power output of the solar cells undergo consistent temporal variations throughout the day, primarily driven by voltage fluctuations, with a peak occurring around noon. Secondly, it is observed that the cells’ performance is significantly more influenced by temporal variations in external light intensity than by temperature changes resulting from variations in flight speed. Finally, the study finds that the impact of flight altitude on the cells’ performance is slightly more pronounced than the influence of temporal variations in external light intensity.
