Site Selection And Lightning Protection For Photovoltaic Power Generation Surge Protectors

Photovoltaic power generation is a new environmentally friendly and sustainable power generation method that is strongly advocated in my country. Compared with traditional thermal power generation, it does not consume various non-renewable energy sources and will not harm the environment. The principle of photovoltaic power generation is to use the photovoltaic effect of solar energy to generate direct current through this potential difference, and then convert the direct current into the alternating current we need through the inverter. So what points should be paid attention to in the site selection of photovoltaic power generation surge protectors, and what are the requirements for lightning protection in the special site selection of photovoltaic power generation?

The most important thing about the site selection of photovoltaic power generation is to choose a place with abundant solar energy. Therefore, it is necessary to choose a place with few obstructions and pay attention to avoiding areas where the air is often polluted by suspended matter. In terms of topography, the site of the photovoltaic power station should be selected in a flat area or a slope area with high north and low south, and the east-west slope of the site should not be too large. In addition, the site selection of photovoltaic power stations should also pay attention to the occurrence of local natural disasters, and should try to choose areas with low incidence of natural disasters such as lightning, mudslides, and floods. After considering these geological reasons, some economic and human factors should be considered.

After the site selection is completed, lightning protection for photovoltaic power generation is the top priority in the protection work. Photovoltaic power stations often have photovoltaic modules, junction boxes, distribution boxes, inverters and other parts. The intrusion of lightning surges often causes them to be seriously damaged. Therefore, photovoltaic power generation needs to select appropriate surge protection device on both the DC and AC sides. The DC side needs to select an appropriate photovoltaic DC surge protective device according to the size of the photovoltaic voltage.
