There is no doubt that cleaning your panels will increase their overall efficiency. According to many statistical observations, this efficiency and performance improvement can be dramatic, up to 21% in residential arrays and up to 60% in commercial installations. So it’s the best way to ensure that your panels are prepped for maximum efficiency. Regular cleaning can make a huge difference!

Many solar panel installation companies as well as manufacturers have specified regular cleaning as a warranty condition. You may not be covered by the warranty if there is no proof of regular cleaning. That’s why regular cleaning is recommended if you want to be on the safe side in case there is a malfunction at some point.

Most solar panel owners don’t clean their panels after it rains because they think they don’t need to because the rain water will do it for them. But that’s not true. Similar to how you need to clean your car’s windshield more often during the rainy season, your solar panels need to be cleaned more often as well. So, it is recommended that you don’t rely on rain water to clean your panels automatically, because it just doesn’t happen.

There are lots of soft grains of sand, dust particles, and debris in the environment. These will eventually build up and contribute to wear and tear when you don’t clean your solar panels regularly. While it may not be obvious at first, over time your panels’ efficiency will decrease and you also risk ending up having equipment that fails much sooner.

Solar panels can be a perfect hiding and nesting place for birds, bugs, and rodents. The problem is these critters can cause major damage to your solar array by biting and chewing cables or reduce efficiency by dirtying your panels. Pests can also void the warranty on your panels and leave you stuck with large repair or replacement costs. We have seen birds nesting in solar panels all over Boise and the Treasure Valley.

Nobody wants an aged-looking, dirt-covered panel adorning their rooftop. Similar to how important it is to clean the rest of your home, it is also essential to take proper care of your solar panels and clean them regularly. This kind of proper maintenance will make your home more aesthetically appealing to both you and your visitors.
