[0002] With the continuous development of social economy and the continuous progress of human civilization, human demand for energy is growing, and energy issues have become a global problem. Solar energy is clean and environmentally friendly, inexhaustible, and does not cause any environmental pollution. It is the most abundant renewable energy available to mankind. Photovoltaic power generation is based on the principle of the photovoltaic effect, using solar cells to directly convert solar energy into electrical energy.

[0003] During the application of existing photovoltaic power generation devices floating on the water surface, there is a lack of effective cleaning of the photovoltaic panels. The dust attached to the photovoltaic panels is mainly cleaned by external precipitation. When rainfall is sparse, excessively thick dust can easily affect the power generation rate, and it is necessary to use a ship-borne high-pressure water gun to wash it. The process is relatively cumbersome. In addition, photovoltaic panels are usually installed at a fixed angle and cannot be adjusted according to the position of the sun. The overall power generation efficiency is low. Summary of the invention
