Photovoltaic power generation is the direct conversion of light energy into direct current energy through the characteristics of semiconductors, and then the direct current is converted into alternating current that can be used by us through the inverter. The photovoltaic module itself does not produce any electromagnetic radiation when generating electricity, but in order to convert the direct current generated by the photovoltaic module into alternating current and realize the connection with the grid, a lot of power equipment and electronic devices are usually required, and these devices will affect the surrounding electromagnetic environment when running. After scientific determination, the electromagnetic environment of photovoltaic power stations is lower than the limit value of various indicators. In the power frequency band, the electromagnetic environment of photovoltaic power stations is even lower than the quantity value generated by commonly used household appliances in normal use, which will not affect human health.

Photovoltaic power is considered to be a green and low-carbon energy source for the following reasons:

1. Zero carbon emissions: The power generation process of photovoltaic power does not involve burning fossil fuels, so there is almost no greenhouse gas such as carbon dioxide (CO2) in the power production stage. This makes photovoltaic power a zero-carbon energy source.

2. Renewable: photovoltaic power is a kind of renewable energy, its main source is solar energy. Solar energy is a continuous natural resource, so under normal conditions, photovoltaic power systems can continuously generate electricity without running out of resources.

3. Low environmental impact: The construction and operation of photovoltaic power systems have a relatively low impact on the environment. While some energy is required to produce solar panels and install photovoltaic systems, these costs are usually covered over the life of the photovoltaic system. The production and use of photovoltaic power has less impact on land, water resources and air quality than traditional forms of energy.

4. Energy security: The power generation process of photovoltaic power does not rely on limited non-renewable resources, such as oil and gas. This gives photovoltaic power an advantage in terms of energy security, as it reduces dependence on imported fossil fuels and reduces sensitivity to geopolitical and market fluctuations.

5. Technological progress: With the development of science and technology, photovoltaic technology continues to improve, improve efficiency and reduce costs. This makes photovoltaic power more viable and sustainable.

Overall, the green and low-carbon nature of photovoltaic power makes it one of the key factors driving a sustainable energy future, helping to mitigate climate change and improve the environmental sustainability of the energy system.

Photovoltaic power generation refers to the use of solar photovoltaic cells to directly convert solar radiation into electricity generation. Photovoltaic power generation is the mainstream of solar power generation today.

Distributed photovoltaic system refers to the construction near the user site, generally access to the power grid below 35kV and below voltage level, the power generation is mainly consumed on the spot, and the balance adjustment in the distribution system is a characteristic of photovoltaic power generation facilities. The operation mode of the distributed photovoltaic system is self-use, residual power online, and full Internet access. Self-use, surplus electricity online means that the power generated by the distributed photovoltaic power generation system is preferentially used by power users, and excess electricity is connected to the grid; Full access to the Internet means that all the electricity generated by the distributed photovoltaic power generation system is connected to the grid.

Distributed power generation follows the principles of local conditions, clean and efficient, decentralized layout, and nearby utilization, making full use of local solar energy resources, replacing and reducing fossil energy consumption.

Commonly referred to as BIPV) and photovoltaic Building Attached PV (English as Building Attached PV, abbreviated as BAPV). The definition is as follows:

1. The distributed photovoltaic system combined with the building is an important application form of the distributed photovoltaic system at present, and the technology is progressing rapidly, mainly in the installation method combined with the building and the electrical design of the building photovoltaic. According to the different installation methods combined with the Building, it can be divided into photovoltaic building integration or photovoltaic building integration (English is Building Integrated PV, that is, flat BIPV: the use of special photovoltaic modules designed to replace the original building materials or building components when installed, and the photovoltaic system integrated with the building. If the photovoltaic modules are removed, the building cannot be used normally. Photovoltaic modules must not only meet the functional requirements of photovoltaic power generation at the same time must first meet the basic functional requirements of the building, such as rugged, thermal insulation, waterproof and moisture-proof, appropriate strength and stiffness and other performance, common photovoltaic tiles, photovoltaic curtain walls, photovoltaic ceilings, photovoltaic Windows and photovoltaic awnings or sunshades.

2. BAPV: The use of ordinary photovoltaic modules, installed on the original building, does not replace building materials or building components, directly installed on the roof or attached to the wall of the photovoltaic system. The removal of the photovoltaic modules on this building will not affect the basic function of the original building.

It usually has the characteristics of small installation capacity, low voltage level grid-connection, simplified filing and grid-connection process.
