Description

Technical Field

[0001] The present invention relates to the field of photovoltaic plant safety technology, and in particular to a photovoltaic field safety operation and maintenance linkage system. Background Art

[0002] The photovoltaic industry is a power generation system that uses solar energy as energy. Its main component is photovoltaic panels. Photovoltaic power generation technology is a popular pollution-free and environmentally friendly new energy. With the continuous advancement of science and technology, the photovoltaic industry has also shown a trend of vigorous development. From the perspective of global new energy forms, photovoltaic power generation is the focus of new energy development.

[0003] With the further development of the photovoltaic industry, photovoltaic power generation will gradually become popular and become an important power source for urban and rural areas. Furthermore, vigorously promoting the application of photovoltaic power generation is of great significance for optimizing the energy structure, improving the ecological environment, and transforming urban and rural energy consumption patterns. The adoption of a "self-generation for own use, with surplus power connected to the grid" model can improve the electricity consumption structure and promote the development of people's livelihoods. We encourage and support distributed photovoltaic power generation projects, such as rooftops, to connect to the grid using this model, and support the transition from "full grid access" to a "self-generation for own use, with surplus power connected to the grid" model. The generated electricity is used by users themselves to solve clean energy problems such as electricity, heating, and cooking, and the excess electricity is fed back into the grid.
