Photovoltaic power generation system converts solar energy into electric energy according to the principle that light produces photovoltaic effect, which has no pollution and radiation. Electronic devices such as inverters and power distribution cabinets have passed EMC (electromagnetic compatibility) tests, so they are harmless to human body.
Moreover, solar photovoltaic power generation does not produce any waste gas, waste water, waste residue and other wastes. There are no rotating parts in the operation process, so there will be no noise pollution.
The principle of photovoltaic power generation is photovoltaic effect. The solar cell module generates direct current under the illumination condition, which is connected to the grid-connected inverter after a certain series-parallel summary, and converted into 5HzAC23V/4V power supply. There is no high-frequency alternating current and electromagnetic radiation in the whole power generation and conversion process, which will not cause harm to human body.
