Low-sunlight solar rural sewage purifier

The invention discloses a low-sunlight solar rural sewage purifier which comprises a plurality of low-sunlight photovoltaic solar panels. Each low-sunlight photovoltaic solar panel is matched with a sunlight tracker and a rotating motor. According to the invention, an energy storage battery pack can be prevented from being overcharged. Under the control of the corresponding sunlight trackers, the rotating motors enable the low-sunlight photovoltaic solar panels to automatically adjust the orientation along with the direction of the sun, so that the sunlight utilization efficiency of the low-sunlight photovoltaic solar panels is greatly improved. One part of the generated electric energy is directly supplied to the sewage purifier under the cooperation of a first boosting transformer, the other part of the generated electric energy is stored in the energy storage battery pack under the cooperation of a step-down transformer, and in addition, the energy storage battery pack automatically supplies power to the s
