We're often asked how to care for RV solar panels and what we have to do to keep them working.
The answer is… hardly anything.
They really take care of themselves, pretty much.
I'm not the sort that likes to do unnecessary maintenance. So when it comes to solar, all I do is clean them once or twice a year.
What to do about dirty solar panels?
Most times, nothing.
Don't stay up at night worrying about dirt on your panels cutting down on the amount of electricity.
It's not a problem, Trust me on this.
No matter what kind of solar panels you have – glass panels mounted in frames or flexible panels affixed directly to the roof surface – experts say you don't need to get do much to keep them clean.
In fact, the available research on static panels in heavily urbanized areas indicates that dirt only cuts down on yield about 3-5%, and that study was done in rain-deprived southern California where they go months with no cleansing showers.
