With the development of photovoltaic industry, thousands of photovoltaic power stations are quietly built on the roof. According to the experience of photovoltaic developed countries such as Europe, the United States, Japan and China, the potential fire risk also follows, and roof photovoltaic power stations have frequent fire accidents.

 

Since May, the temperature has increased day by day, and the pace of summer is getting closer and closer. As we all know, the peak power temperature coefficient of general photovoltaic modules is between -0.38 ~ - 0.44% / ℃. When the temperature rises by 1 ℃, the output power of photovoltaic modules will decrease by 0.38 ~ 0.44%, which will not only affect the power generation, but also easily induce fire.

The service life of the photovoltaic system is theoretically 20-25 years. With the increase of the operation life of the photovoltaic power station, the electronic components in the inverter will have problems such as aging, cable rupture and loose contacts. These internal reasons of the system may cause fault arc. Generally, the installation of photovoltaic arrays mostly uses a long string of high-voltage DC power supply, It indirectly increases the safety problems related to arc.

 

Therefore, for users and manufacturers, regular maintenance of the power station is essential. First, check whether the photovoltaic equipment operates with disease, extended service or overload. This is why more and more solar panel installation manufacturers cooperate with experienced thermal imagers who provide conventional thermal imaging inspection services to ensure the safe and effective deployment of solar systems.
