Solar panel systems are incredibly durable and require little to no maintenance over the 25-30 years that you will have them. A few times a year, the panels should be inspected for any dirt or debris that may collect on them. Solar panels are made of tempered glass, so they’re built to withstand hail and other rough weather. With the exception of tracking mounts, solar panel systems don’t have movable parts, so this also cuts down on the possibility of any problems. When there is an issue, it’s usually related to production. That’s why it’s always advisable to monitor your system’s production so that you will be aware of any problems and be able to proactively address them.
It’s generally not necessary to clean your solar panels and most warranties don’t require regular cleanings. If you live somewhere where there is a lot of smog, dust, or dirt, it’s possible that you may see a dip in your production that might require cleaning your panels. Cleaning your panels is similar to cleaning your windshield. Depending on where your panels are mounted, however, your best option is to hire a professional cleaning service versus cleaning them yourself.
