[0002] Solar energy is currently the most abundant natural resource on Earth. In addition, solar energy is easy to transport and its clean and pollution-free characteristics have greatly promoted the development of green new energy. In order to convert solar energy into usable energy, photovoltaic panels are usually used to collect and convert solar energy.

In hot weather, the frequency of water spraying increases greatly, resulting in a waste of water resources, and the sunshade net will block the photovoltaic panels and affect their power generation efficiency.
