In the face of bad weather, the maintenance of photovoltaic brackets

According to the forecast of the National Climate Center, the equatorial Middle East Pacific Ocean will maintain El Nino status in the next three months, and the SST index will continue to rise, and an eastern El Nino event of medium intensity will be formed in the autumn of this year, which may lead to more frequent, wider and stronger extreme weather.

Since the design and operation cycle of photovoltaic brackets is as long as 25-30 years, it is bound to experience extreme weather many times during its long life cycle. So, what should be done to ensure that components operate reliably at high temperatures?

1. Check the equipment of the power station

After the arrival of extreme weather, checking the normal communication of the monitoring system of the power station is the first work. The normal communication of the photovoltaic power station monitoring system will help you to know whether the entire photovoltaic power generation system is operating normally and generating power in the first time, and it can also allow maintenance personnel to accurately lock the failure of the system. Check whether the doors of inverters, bus boxes, distribution boxes and other equipment are locked, whether there is rust loose, broken leakage phenomenon, whether the photovoltaic cables between components fall off, if the above situation occurs, be sure to contact maintenance personnel in time.

2. Ensure that the drainage system of photovoltaic power station works normally

Due to heavy rainfall weather, most of them will cause water, so the most important thing is to ensure that the drainage system is smooth, to ensure that the drainage pipes and drainage ditches in the photovoltaic power station area are free of debris, garbage and other items, so as to avoid blocking when precipitation. When the photovoltaic power generation system is in the water environment for a long time, on the one hand, there will be leakage, causing great danger to the person; On the other hand, it will also accelerate the oxidation and damage of photovoltaic supports and legs, affecting the overall life of photovoltaic power stations.

3. Strengthen the components and brackets of the photovoltaic power station

The wind phenomenon brought by bad weather may take loose components and supports, then it is necessary to strengthen the components and supports of the photovoltaic power station to prevent some potential safety hazards and direct economic losses.

4. Keep ventilation and heat dissipation

In general, when the photovoltaic power station is designed, the bracket is usually raised to ensure that there is enough space before and after the component, in order to ensure the circulation of air and achieve the purpose of cooling. In addition, the metal frame around the component also has a certain heat dissipation effect, and daily protective maintenance needs to be paid attention.

Harsh climatic conditions are unavoidable, and man is still very small before the laws of nature. What we can do is to continuously break through the technical barriers of the industry, so that photovoltaic products can face various challenges more effectively. The reliability of photovoltaic products is still the strongest guarantee for photovoltaic power plants to cope with extreme weather.

Continuous exploration, the pursuit of progress, Link Solarenergy is always on the road.
