In addition to the quality of the modules and solar panel brackets, the life of the PV station depends largely on whether the post-maintenance work is done well. So what specific measures should be taken to ensure that the photovoltaic power station can maintains a stable and reliable income under severe weather such as high temperature, heavy rain, and thunder and lightning? Here are some suggestions for your reference:

1、 High temperature protection

① Clean the shelter on the modules in time to maintain the ventilation and heat dissipation of the modules.

② Avoid high temperature periods, and clean modules in the morning or evening.

Note: During the high temperature period, sudden cooling will cause temperature difference in module glass, which may lead to module rupture. Therefore, it is necessary to select the time when the temperature is low in the morning and evening.

2、 Storm prevention

① During the design of the power station, geographical and geological factors shall be taken into account, such as the orientation of the site, the degree of slope fluctuation, potential geological hazards, ponding depth, flood level, drainage conditions, etc.

② When purchasing the solar mounting system, pay attention to the surface treatment and corrosion resistance of the racking. For example, CORIGY SOLAR's aluminum solar panel mounts adopts anodizing treatment, with smooth and flat surface coating and has strong corrosion resistance. CORIGY SOLAR's steel solar panel mounting rails is use hot-dip galvanized with an average coating of 80 μm, and it meets international standards and is more secure.

③ For the built power station, the drainage system shall be scientifically added.

Note: During patrol inspection, operation and maintenance in rainy days, it is necessary to avoid electrical operation with bare hands, and do not directly touch the inverter, modules, cables and terminals with bare hands. It is necessary to wear rubber gloves and rubber boots to reduce the risk of electric shock.

3、 Lightning protection

Lightning protection facilities of photovoltaic power station shall also be checked regularly. In the current lightning protection measures, the most effective and extensive method is to connect the metal parts of electrical equipment with the earth. The grounding system consists of four parts: grounding equipment, grounding body, lead-in line and earth.

In short, in order to ensure the healthy and long-term operation of the power station and the stability and sustainability of power generation and income, regular patrol inspection and maintenance of the power station are required. During maintenance, avoid overhauling electrical equipment and lines by hand to prevent electric shock. Buying photovoltaic insurance in advance is also a good way to avoid risks.
