When it comes to solar energy, the pros far outweigh the cons. One of the great advantages of solar energy is the longevity of the components. The panels typically have a lifespan of over 25 years and, depending on the complexity of the system, have few or no moving parts. But that doesn't mean they can't be damaged by weather conditions and other factors.
1. Age
Solar panels can withstand significant external stress. However, they have limits. Solar modules are made of several layers of material surrounded by a metal frame. The adhesive holds the layers together and resists atmospheric effects. The silicone seal also covers the fine seams to provide additional protection.
But some things can happen with age. Seals and adhesives can harden and weaken and allow water to seep into the solar panel, negatively affecting its ability to produce electricity (and essentially rendering them useless). Air pollutants deposited on the glass surface can cause exterior damage when wind blows these particles away. Other aging factors include cell degradation and contamination, which can worsen if the solar panel is not maintained.
2. Remove waste
Tree branches and other debris falling from above can damage solar panels for simple reasons. Although solar panels are solidly constructed, they are not indestructible. A falling tree branch can break the glass of the solar panel and even damage the solar cells protected by the glass. Sports equipment such as stones and balls can cause similar damage to solar panels.
3. Other waste
dirt, e.g. B. Floating particles are not immediately visible, but can damage the protective glass of the solar modules. These particles may or may not be visible as they fly, and each causes only minor damage in the form of etching on the glass. Even in the nation's cleanest air, many particles can cause problems over time.
4. Water
As it ages or due to manufacturing defects, water entering the solar panel can damage the internal components, rendering them unusable or degrading their quality. Solar panels can withstand water from most sources such as rain and dew. The panels also have built-in methods to drain any water that enters.
However, broken joints can allow harmful water ingress that the panel cannot resist.
5. Storms
Solar panels can handle most of the elements that nature throws at them. However, high winds and hail, debris, and wind-blown tree parts can shatter glass and damage even the strongest solar panels.
How to identify solar module damage
There are several ways to detect damage to solar panels. A visual inspection may reveal broken or cracked glass, a frame or mounting problem, or problems with damaged or cut wiring.
The inverter may also display an error message if it is designed to do so. Or you may experience a drop in power from your system, indicating an internal problem with the solar panel.
