When installing a photovoltaic power station, you need to take lightning protection measures for the photovoltaic power station, such as grounding, safe arrangement of cables, etc.
However, thunderstorms still have a certain impact on photovoltaic power stations.
First of all, if it is daytime during a thunderstorm, the photovoltaic power station will generate almost no power, because there is no light on rainy days, and the photovoltaic power station cannot generate electricity.
Secondly, if the thunder strikes the photovoltaic panel during thunderstorms, it is very likely to cause the components to be struck by lightning and catch fire, causing safety accidents, so it is very important to take lightning protection measures;
Finally, after taking lightning protection measures, the huge lightning strike wave is likely to damage the inverter of the photovoltaic power station. From the actual cases, in thunderstorms, the inverter of the photovoltaic power station is the easiest and most likely to be damaged by lightning.
Distributed photovoltaic power generation systems are equipped with lightning protection devices, so there is no need to disconnect them. For safety reasons, it is recommended to disconnect the circuit breaker switch of the junction box and cut off the circuit connection with the photovoltaic module to avoid the harm caused by direct lightning that the lightning protection module cannot remove. The operation and maintenance personnel should promptly detect the performance of the lightning protection module to avoid the harm caused by the failure of the lightning protection module.

What are the usage scenarios/application areas of photovoltaic tiles?
Photovoltaic tiles integrate solar power generation products into buildings, so they have the dual characteristics of building materials and power generation. It gives traditional building materials the ability to generate electricity, allowing buildings to generate electricity. Photovoltaic tiles have a variety of power generation application scenarios and are widely used in industrial and commercial roofs, tourist landscapes, antique buildings, awnings, parking sheds and other fields.

What occasions are distributed solar power generation systems suitable for?
Distributed photovoltaic power generation refers specifically to photovoltaic power generation facilities that are built near user sites, with the operating mode of self-generation and self-use on the user side, excess electricity connected to the grid, and balanced regulation in the distribution system. Distributed photovoltaic power generation uses photovoltaic modules to directly convert solar energy into electrical energy. It is a new type of power generation and comprehensive energy utilization method with broad development prospects. It advocates the principle of nearby power generation, nearby grid connection, nearby conversion, and nearby use.

As long as there is sunlight, the photovoltaic modules will have electricity, so the power supply cannot be cut off when there is sunlight, and due to the accumulation of series voltage, the corresponding voltage to the ground will also be very high. Therefore, the installation process should strictly comply with the installation and use instructions provided by the system supplier and be completed by professional installers. The wiring part of the equipment is installed using professional connectors with a protection level of IP65. The electrical equipment is also protected by air switches to prevent leakage current from causing harm to life.
