As an installer or owner, after the hail occurs, you must check the photovoltaic power station.
First of all, the comparison also checks the power generation of the power station. If there is a drop in power generation or other abnormal conditions, further inspections can be performed on components that may have problems.
The method of checking the fault location of the photovoltaic module: generally use a thermal imager to find the abnormal heating part of the module, or use a portable EL tester to detect the possibly damaged module, which can quickly find the place where there are [hidden cracks] or damage.
If you still cannot determine whether the components are damaged, you can contact the original factory for inspection, so that the damaged components can be replaced in time.
To sum up: before the construction of the power station, you must choose products from regular channels, and at the same time find a reliable installer for installation. After the hailstorm, it is necessary to check the power generation of the power station to confirm whether it has been damaged.
If the frequency of local hail is high, you can find an insurance company to purchase property insurance for photovoltaic power plants.
