Is photovoltaic power harmful to the human body? Does a domestic photovoltaic power station have radiation? Many people want to install photovoltaic power generation systems on the rooftops of their villas or in the countryside, but they are also worried that photovoltaic power generation may be harmful to the human body. In fact, as long as you understand the principle of photovoltaic power generation, this fear will disappear.
Electromagnetic radiation is a major cause of cardiovascular disease, diabetes, and cancerous mutations. And harm the human reproductive system, nervous system and immune system.
Photovoltaic modules do not generate any electromagnetic radiation when they generate electricity. However, in order to convert the direct current generated by a photovoltaic module into alternating current and connect it to a power grid, a lot of power equipment and electronic devices are usually required. These equipments will affect the surrounding environment during operation. The electromagnetic environment.
The electromagnetic environment of a photovoltaic power generation system refers to the sum of electromagnetic phenomena existing in the periphery of the photovoltaic system due to the operation of the photovoltaic system. In the electric power field, 50 Hz (or 60 Hz) frequency is generally referred to as "industrial frequency" (abbreviated as "power frequency"). Household appliances used in our living environment, such as television sets, vacuum cleaners, refrigerators, electric blankets, electric shavers, etc., will all generate power frequency electromagnetic fields. According to scientific determination, the electromagnetic environment of solar photovoltaic power generation system is lower than the limits of various indicators. In the industrial frequency band, the electromagnetic environment of solar photovoltaic power stations is even lower than the value generated when normal home appliances are used normally, and will not affect human health. .
Therefore, for the question “Is PV power harmful to the human body?”, it can be clearly stated that photovoltaic power plants will not generate any electromagnetic radiation during the conversion of solar energy into electricity, and only when DC power is converted to AC power. Only a small amount of electromagnetic radiation will be produced, and it is lower than common household appliances.
Lear Solar developed a photovoltaic cleaning robot specifically for distributed photovoltaic power plants. It is used for photovoltaic panel cleaning, intelligent full automation, and increased power generation.
