Technical Field

[0002] Photovoltaic panel is the abbreviation of solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two modes of operation: independent operation and grid-connected operation. At the same time, solar photovoltaic power generation systems are classified into two types: centralized, such as large-scale northwest ground photovoltaic power generation systems; and distributed, such as photovoltaic power generation systems on the roofs of industrial and commercial enterprise factories and residential rooftop photovoltaic power generation systems.
