Cleaning solar panels is not as stressful as you probably thought. The only maintenance that solar panels may need is to be washed due to soiling and dirt build up.

Google did a study, where they tested a set of flat panels and a set of tilted panels. They didn’t wash either set of panels for 15 months.

When they cleaned the flat panels, the production doubled overnight. 8 months later they cleaned the panels again and the output increased by 36%. As you can see, it’s definitely worth it to clean flat panels.

When they cleaned the titled panels, there was only a small increase in energy output because the rain was able to clean the panels sufficiently.

Since your panels will be tilted, you won’t really need to wash your panels unless you live in a particularly dry climate. Otherwise, the rain will do a great job to keep your panels performing at their best.
