Hail damage to PV systems
can be significant

As brief as hailstorms can be, they can often cause significant damage. Depending on the size of the hailstones, there is often significant damage not only to vehicles and plants, but also to PV modules in particular. And with climate change, not only the has the frequency of hailstorms increased – the size of the actual hailstones has also increased. Furthermore, the difference in the degree to which different regions in Germany are impacted by hailstorm damage is evening out.

Let us assess your solar modules
for hail damage

Cotact SUNLAB after a hailstorm to have your modules checked for damage. You then have the opportunity to react and prevent any performance impairment. Minor damage that may not be immediately visible to the naked eye can also affect the performance of the modules.


Hail can cause
the following damage:

Microcracks / cell breakages

These are often not visible to the naked eye, but affect the life of the module.

Detecting glass damage to the solar module from hail

This usually involves obvious damage to the glass surface of the module. As a result, the entire system may fail.

Frame damage

This can lead to performance impairment, for example, due to an insulation fault.

The following information and codes will help you to find us in search engines:

Detecting hail damage for insurance purposes. Detecting hail damage to the photovoltaic system. Focus on precision right from the beginning. Functional testing and assessment for damage to the PV system solar modules. This can be detected in the photovoltaics at the outset. Microcracks caused by hail impair the function of a module. This aspect is also of interest for building insurance, as well as to operators of photovoltaic systems. Ultimately, you want to avoid a reduction in the performance of your solar modules. However, after a storm, cracks in cells can be detected. Assessing damage to solar cells using methods such as electroluminescence. And detecting such damage. Also EL measurement of the module. If other relevant codes are used: EN standard protection.

Other search engine-relevant terms:

SUNLAB can make invisible hairline cracks clearly visible to PV system operators. In the event of light and current analysis. For manufacturers and other interested parties. Show fluorescence right from the start. The testing may initially lead to costs compared to modules that have not been tested. However, when damage has been detected, the results have an effect since the customer can then make the correct conclusions, such as to replace items.
