Add pollen, bird droppings and leaves from the tree next door, and the panels you paid for are producing less than they should, right at the start of the summer when they should be doing their best work. Most cleaning services wash the panels and tell you it helped. We measure it. You get a performance reading before we start and another when we finish, so you can see exactly what the clean was worth. And if your panels do not need cleaning, we will tell you that too.

No detergents, no pressure washers, nothing abrasive - We never walk on the panels. It cracks cells you cannot see and voids the module warranty - Leaves, debris and nesting material cleared from under and around the array - Done early in the day, before the panels heat up ## Before and After We take a performance reading before the clean and again afterwards, measured against the sunlight falling on the panels at the time, so a cloud passing over does not distort the result. You get both numbers and before-and-after photographs in a short record of the job. ## While We Are Up There Cleaning puts us close to every panel on the roof, so we look while we work. Cracked glass, discolouration, loose cabling, damaged mounting, birds nesting under the array: anything we see goes into the job record with a photograph. It is not an inspection, and we will not pretend it is. If we see something that needs a proper look, we will say so and suggest a [Health Check](https://cleanvolts.co.za/health-check?hsLang=za). ## How Often Should Panels Be Cleaned in Gauteng? **For most homes, twice a year.** Once at the end of the dry winter, around August or September, before the summer production peak. Once in mid-summer if the site is dusty. **More often** if you are near an unpaved road, a mine dump, a building site or farmland, or under trees that attract birds. These sites can need attention every quarter. **Less often** if your roof is steep and summer rain does some of the work. Some systems manage on one clean a year. ## Price Priced per panel, depending on how easy the array is to reach: - Ground-mounted, or single-storey with easy access - Single-storey with difficult access or a steep pitch - Double-storey - Arrays that need specialist access equipment are quoted per job Tell us how many panels you have and where they are, and we will give you the figure before we book. ## What Is Not Included Panels we cannot reach safely, roof cleaning, gutter cleaning beyond the array, and removing established bird nests, which we quote separately because it sometimes needs a specialist.  ## Cleaning as Part of a Plan  If you would rather not think about it, cleaning is built into our [service plans](https://cleanvolts.co.za/service-plans?hsLang=za): one clean a year on the Complete plan and two on Complete Plus, alongside the annual service and monitoring.  ## Where We Work Blairgowrie, Linden, Randburg, Ferndale, Northcliff, Fairland, Emmarentia, Greenside and Parkhurst, and the suburbs around them.  ![CleanVolts](https://cleanvolts.co.za/hs-fs/hubfs/apple-touch-icon-180.png?width=180&height=180&name=apple-touch-icon-180.png) ### Book a Clean Book online, or send us the number of panels and a photo of the roof on WhatsApp and we will quote.  [Book Now](https://cleanvolts.co.za/book-an-audit?hsLang=za) [![CleanVolts](https://cleanvolts.co.za/hs-fs/hubfs/clean%20volts%20logo-2.png?width=1200&height=336&name=clean%20volts%20logo-2.png "CleanVolts")](http:/?hsLang=za) - Services - Guides - About - For Partners --- [Privacy Policy](https://cleanvolts.co.za/privacy-policy/?hsLang=za) · © 2026 CleanVolts.
