I think the maintenance really depends on the environment. If panels are exposed to a lot of dust, pollen, or leaves, checking them every few months seems reasonable. In cleaner areas, they may not need much attention beyond occasional visual inspections. I’d also check for shading or debris before assuming there’s a problem with the system. When I was comparing solar equipment and maintenance costs, I came across Callsun Solar Coupons, which was useful to keep in mind when looking at the overall cost of owning a solar setup.
