Solar panels are not unbreakable. However, the modern panels were developed to last from 25 to 30 years. While they are still prone to damage, they can withstand various weather elements and have strong impacts.
It’s only apt to say that they are durable but can still break due to certain extreme elements. They are made from high-strength glass that protects the solar cells placed inside. A back sheet serves as protection and a layer of insulation under the glass.
The panels undergo an advanced manufacturing process that protects them from heat and humidity. It enables the PV system to deliver efficient output. The panels can absorb maximum energy from the sun due to their anti-reflective coat.
What Can Break the Panels?
Here are some of the extreme elements that can damage or break your solar panels:
Hail storms
They are among the top causes of the breakage of the panels. There is nothing you can do to prevent them from happening. However, if you live in a hailstorm-prone area, it is best to have smaller panels installed to minimize the damage at each occurrence.
Falling debris
Small and light debris can scratch the panels. They include leaves, twigs, and dirt. They may be light scratches but already enough to affect your panel’s efficiency. The debris hinders certain parts of the panel from exposure to the sun, decreasing its absorption rate.
It is best to have the panels installed in areas without trees nearby. You also must keep the panels regularly cleaned to remove the debris before they accumulate.
Dysfunctional components
If you don’t see obvious damage to the panels, but they are not working as expected, the problem can be due to dysfunctional parts. The most likely culprit, in this case, is the inverter, but it can also be due to blown fuses or disconnection.
Have a technician check your solar energy system, and never try to repair the issues on your own, especially when you don’t know how and don’t have the tools.
Water damage
Water can cause damage to your panels, just like what it can do to your home. Water damaging PV panels usually come from damaged or old seals. Water sealant may be effective, but it doesn’t last forever. It becomes crusty or loses the stickiness as it ages. As it happens, water leakage occurs because the sealant is no longer effective in blocking the moisture.
Before it happens, you must acquire your contractor’s services to reseal the panels. They can also look into the whole system to check what else can be done to improve its efficiency.
