How much output do dirty solar panels lose?

It varies with the soiling. Studies commonly show losses of 5 to 20 percent for soiled panels, and more where bird droppings shade individual cells. Coastal salt film in Albany builds up faster than inland dust.

How often should solar panels be cleaned?

For most Albany and Great Southern homes, once or twice a year. Panels on low-pitch roofs, near the coast, or under trees and bird flight paths need it more often.

Can’t I just clean the panels myself?

We would rather quote you a clean than see you on a wet roof. DIY cleaning with tap water and detergent also leaves mineral spots and residue. We use deionised water, which dries completely spot-free.

Will cleaning void my panel warranty?

No, the opposite. We use the gentle, chemical-free method manufacturers recommend, and some warranties actually expect periodic cleaning as basic maintenance.
