Photovoltaic system

The photovoltaic system is a power generation system that converts solar energy into electric energy, and the principle is photovoltaic effect. The photovoltaic system is divided into independent solar photovoltaic power generation system, grid-connected solar photovoltaic power generation system and distributed solar photovoltaic power generation system. It features high reliability, long service life, no pollution to the environment, independent power generation and grid-connected operation, and is favored by the governments and business organizations of various countries and has broad development prospects.

With many years of experience in engineering construction, investment and operation in the field of new energy such as photovoltaic power generation, Risun Group has all qualifications for general contracting of new energy engineering, including engineering planning and design, general contracting of construction, operation, maintenance and overhaul.

The photovoltaic array converts solar energy into DC electric energy. After the DC and AC inversion by the inverter, the voltage class of the photovoltaic power station connected to the grid is determined according to the technology of the photovoltaic power station connecting to the grid and the capacity of the photovoltaic power station. After the voltage is boosted by the transformer, the photovoltaic power station is connected to the medium-voltage or high-voltage grid.
