Cleaning Solar Panels

Solar panels require little maintenance, but it’s still a good idea to check them every now and then. The panels have a dirt-repellent coating, and rain also helps keep them clean, but not all stains will come off easily. You can clean solar panels yourself or have them cleaned.

Cleaning Solar Panels

Solar Panels Panels installed at an angle of more than 20 degrees are often washed clean by the rain. Panels that are tilted less steeply or lie completely flat do need some help, though. It’s a good idea to clean these solar panels once a year. A specialized company can clean solar panels, or you can do it yourself. The main advantage of hiring a company is the convenience. The downside is that it can be quite expensive.
Are you planning to clean your solar panels yourself? If so, always prioritize your safety and protect yourself when you go up on the roof. It’s best to clean the panels with deionized water and a soft cloth or sponge. It’s better to use deionized water instead of regular tap water. Tap water contains lime scale, which can leave residue on the panels. Another option is to collect rainwater and use it for cleaning. Using a soft cloth or sponge will prevent scratches. Never use a scouring pad or a pressure washer, as these can seriously damage your solar panels.

Don't forget your inverter

While many people do clean their solar panels, they often overlook the inverter. However, by checking it regularly and removing dust, you can extend its lifespan. So be sure to include it in your cleaning routine.

Keep an eye on your earnings

In addition to cleaning your solar panels regularly, it’s a good idea to keep an eye on your energy output. If you notice an unexpected drop in your output, it could be a sign that something isn’t working properly. In that case, check to see if your inverter is still working properly or if it needs maintenance.
