With the development of the photovoltaic industry, thousands of photovoltaic power plants have been quietly built on the roof. According to the experience of PV developed countries such as Europe, the United States, Japan, and China, the potential fire risk also followed, and the roof photovoltaic power stations frequently caught fire. ACCIDENT.
The service life of photovoltaic systems is theoretically 20 years to 25 years. With the increase in the operational years of photovoltaic power plants, there will be problems such as aging, broken cables, and loose contacts in inverters. Internal causes of these systems may cause failures. In arcs, the installation of photovoltaic arrays usually uses long strings of high-voltage DC power supplies, which indirectly increases arc-related safety issues.
Therefore, for users and manufacturers, regular maintenance of the power station is indispensable. The first thing to check is whether the photovoltaic equipment is operating in a sick or out-of-service state or is overloaded. This is why more and more solar panel installation companies collaborate with experienced thermal imagers who provide conventional thermal imaging inspection services to ensure the safe and effective deployment of solar energy systems.
As the temperature rises, the efficiency of solar panels will decrease and the amount of power generation will decrease. Some defects can cause them to malfunction and even cause reverse currents, damaging the entire solar device.
Of course, we must pay attention to the cleanliness of photovoltaic panels at ordinary times, because if there are obstructions on the photovoltaic panels, it will cause the hot-spot effect of the photovoltaic panels to generate heat unevenly, which will cause the photovoltaic panels to be damaged or even catch fire. Therefore, regular cleaning of photovoltaic panels is very important.
The above are some methods of fire protection for photovoltaic power plants. In addition to checking whether photovoltaic equipment is normal, cleaning of photovoltaic panels is also an effective method to prevent fires.
