Classification of photovoltaic power generation

Distributed photovoltaic power generation system, also known as distributed power generation or distributed energy supply, refers to the configuration of smaller photovoltaic power generation and supply system at or near the user site to meet the needs of specific users, support the economic operation of existing distribution network, or meet the requirements of both aspects.

The basic equipment of distributed photovoltaic power generation system includes photovoltaic cell module, photovoltaic array bracket, DC combiner box, DC distribution cabinet, grid-connected inverter, AC distribution cabinet and other equipment, as well as power supply system monitoring device and environmental monitoring device. Its operation mode is that under the condition of solar radiation, the solar cell module array of the photovoltaic power generation system will transfer the solar energy converted and output into the DC distribution cabinet through the DC combiner box, and the grid-connected inverter will invert the current to supply the building‘s own load, and the excess or insufficient power will be adjusted by connecting to the grid.
