South Africa
RobCon Electrical services the whole of Gauteng for solar panel cleaning — Pretoria, Centurion, Midrand, Johannesburg, the East Rand and the West Rand. Whether it is a single home or a portfolio of commercial sites across the province, we clean with the same soft-brush method and quote the same clear per-panel rate.
Most Gauteng systems benefit from a professional clean every 6 to 12 months, more often near construction or mining.
We regularly clean solar systems in and around these areas — if yours isn't listed, ask anyway.

Per panel · 100+ panels
Arrays below 100 panels are R35 per panel. Minimum call-out applies. Prices exclude VAT.
We quote the same per-panel rate across Gauteng — R35 per panel below 100 panels and R25 per panel from 100 panels, excluding VAT — whether the site is in Pretoria East or on the West Rand. Multi-site portfolios are quoted on total panel count across all the sites rather than site by site, which is usually the cheaper way to do it.
Gauteng has a genuinely seasonal soiling pattern: dust builds from April, veld-fire ash lands through the dry months, and by September most arrays are at their worst just as the days get long enough to matter. If you clean once a year on the Highveld, do it in spring.
Since our panels have been cleaned, our solar generation have been 32% higher. Great and trustworthy team — I should have done this much sooner! We forget how much dust our panels accumulate.

Contacted Andre Roberts — he promised to see that the solar problem we had was fixed within a week. It's now 4 days later, Andre visited me in person and my problem is fixed. Thanks to Andre for keeping his promise and providing me with great service!

Questions we get asked
All of it — Pretoria, Centurion, Midrand, Johannesburg, the East Rand and the West Rand, including Kempton Park, Benoni, Boksburg, Krugersdorp and Vereeniging.
No. The per-panel rate is the same across the province: R35 per panel below 100 panels and R25 per panel from 100 panels, excluding VAT, with a minimum call-out.
Ideally in spring, after the dry Highveld winter has laid down months of dust and veld-fire ash and before the long summer generation season. Sites near construction, mining or industry usually need a second clean during the year.
RobCon Electrical charges R35 per panel for arrays below 100 panels, and R25 per panel for arrays of 100 panels or more. A minimum call-out applies and prices exclude VAT. A 12-panel home system therefore starts at around R420 excluding VAT.
Most solar systems in Gauteng benefit from a professional clean every 6 to 12 months. Clean more often if the property is near construction, on a busy road, surrounded by trees, close to mines or industrial areas, or frequently visited by birds. Waiting until panels look dirty usually means production has already been lost.
Yes. Dust, pollen and bird droppings block sunlight from reaching the cells, so a soiled array produces less than it was designed to. One RobCon client in Midstream measured 32% higher generation after a professional clean. The exact gain depends on how dirty the panels were and how long since the last clean.
