How Much Maintenance Is Required?

Not much.

Even if you slack off, your solar energy system will operate effectively. If you want your system to soak up its maximum potential, though, you can do a few simple things on a regular basis:

Clean off the panels and collectors once or twice a year with a hose and a soft bristled brush. This can boost performance, especially if pollen, dirt or debris has accumulated.

Keep an eye on your system’s production and look for significant changes in output.
