What Damages a Solar Panel?
What Causes Solar Panel Damage?
People in Las Vegas, NV with solar panels should feel confident that their investment should last and they won’t have to worry about panel damage. While the weather doesn’t always cooperate with our wishes, these renewable energy systems are designed to withstand a fair amount of what Mother Nature throws their way.
Although the many photovoltaic cells that make up a panel are fragile, they are protected by a durable frame and tempered glass. Similar to cellphone screens, even if they shatter or crack, they maintain their form. The glass used is tested to provide a protective layer from hail, wind, and severe storms, as well as hold up to excess weight on them.
Solar panels are designed to last up to 30 years, and may even continue working at a lower capacity after that, but they aren’t 100% resistant to the effects of nature. When general roof damage occurs, there may be a chance that there is also panel damage. The most common causes of damage include:
Falling debris – Dust, leaves and twigs may create tiny scratches that can eventually block some of the cells from absorbing sunlight. Larger branches falling have the potential to create large cracks. Maintaining nearby trees can help deter these problems.
Hail – Panels are designed to withstand hail. For people who live in areas prone to hail storms, or freak storms with larger hail, scratching or cracking can happen. While there isn’t much you can do to prevent hail damage, smaller panels can reduce overall damage.
Rain and snow – As panels age, seals can begin to deteriorate. This may allow moisture to get inside the panel and affect its components. A professional can reseal the panels to help them last as long as they should.
Most people won’t need to worry about panel damage for years to come. A few small steps, like keeping panels free of debris, can easily be added to your spring and fall home maintenance checklist.
