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.
