Solar Panels and Storms

8/16/2021 (Permalink)

You may be wondering what will happen to your solar panels during a major storm. After all, while your panels are durable, they are not indestructible.

In general, panels should be able to survive harsh weather conditions. However, panel damage can still occur during storms. Below are some common causes of harm to these panels.

Lighting

Lightning strikes can destroy your panels. Thankfully, there are products available that can protect the panels from electrical harm. For instance, you can install a surge protection device for the panels.

Fire

Lightning can also spark fires that cause solar panel or roof damage. It is not just the flames themselves that can harm your panels. Extreme heat alone may cause them to malfunction. Adding fans or another form of ventilation may help.

Snow

Of course, destructive storms do not just include lightning. They can also bring heavy rain or snow. Snow can build up on top of the panels. To prevent panel damage, this snow should be removed immediately.

Falling Debris

Storms may also cause large branches to strike your panels. While this debris might not break the panels, the falling objects may make your panels less efficient over time.

Still, solar panels are strong. If the anchor and racking can survive high winds, your panels should be secure during hurricanes and rainstorms. In fact, a 2017 hailstorm that pounded the Denver area only broke one solar panel at the National Renewable Energy Laboratory in nearby Golden. The lab has more than 3,000 panels on its campus. Researchers from the NREL have developed tests to ensure that various panels on the market can withstand harsh conditions.

Your panels should be able to withstand storms. Best of all, any solar panel damage that does occur may not be permanent! If we can assist you in any way, give us a call at 636-467-5444.
