The invention relates to the technical field of miniature unmanned aerial platforms, in particular to a miniature solar unmanned aerial vehicle system which comprises an unmanned aerial vehicle body and further comprises a solar cell used for collecting light energy of the surrounding environment and converting the light energy into electric energy so as to supply power to the unmanned aerial vehicle system. The micro MPPT chip is used for tracking the maximum power point of the solar cell in real time by changing the equivalent load of the micro MPPT chip; and the energy storage battery is used for supplying power to the unmanned aerial vehicle system and automatically charging the unmanned aerial vehicle system through the solar battery. The total weight of the miniature solar unmanned aerial vehicle system is smaller than or equal to 30 g, when the electric quantity of the energy storage battery is insufficient or lower than a preset value, environment light energy can be automatically collected, the energy storage battery can be charged, secondary flight of the unmanned aerial vehicle is achieved, and the continuous working capacity of the unmanned aerial vehicle is improved. Compared with the prior art, the feasibility of the miniature solar unmanned aerial vehicle is verified, and relevant technical vacancies at home and abroad are made up.
