Cleaning solar panels

Solar panels require little maintenance, but it is good to check them every now and then. The panels have a dirt-repellent coating, and the rain also helps to 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 that are set up at an angle greater than 20 degrees are often already washed clean by the rain. Panels that lie flatter or completely flat do need some help. It is smart to clean these solar panels once a year. A specialized company can clean solar panels or you can do it yourself. The big advantage of hiring a company is convenience. The downside is that it can be quite pricey.
Are you going to clean your solar panels yourself? Then always pay attention to your safety and protect yourself when you go on the roof. The best way to clean the panels is with osmosis water and a soft cloth or sponge. Use osmosis water rather than ordinary tap water. Tap water contains calcium which can remain on the panels. Another option is to collect rainwater and use it for cleaning. Use a soft cloth or sponge to prevent scratches. Never use a scouring pad or high-pressure cleaner, as these can seriously damage your solar panels.

Don't forget your inverter

While many people do clean their solar panels, they often skip the inverter. However, by regularly checking it and making it dust-free, you can extend its service life. So include it in your cleaning.

Keep track of your yield

In addition to regularly cleaning your solar panels, it's a good idea to keep an eye on your yield. If you see that your yield is unexpectedly declining, it could be a sign that something is not working properly. In that case, check if your inverter is still working properly or if any maintenance is needed.
