Solar photovoltaic power generation: When sunlight shines on some special materials, it can cause the movement of electrons in the materials, forming a potential difference. Solar photovoltaic power generation is based on this principle, using solar cells to directly convert solar energy into electrical energy. Solar photovoltaic power generation system is a new type of power generation system that utilizes the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. There are two modes of operation: independent operation and grid connected operation. Independent photovoltaic power generation systems require batteries as energy storage devices, mainly used in remote areas without power grids and densely populated areas, and the overall system cost is very high; In areas with public power grids, photovoltaic power generation systems are connected to the grid and operate in parallel, eliminating the need for batteries. This not only significantly reduces costs, but also has higher power generation efficiency and better environmental performance.
