Gauteng
Centurion has one of the highest densities of rooftop solar in Gauteng, largely across secure estates and townhouse complexes. RobCon Electrical cleans individual homes as well as full complex and body-corporate installations in Centurion, and we are comfortable working within estate access and contractor rules.
For complexes and estates we quote per panel across the whole site, which usually lands well under the single-home rate.
We regularly clean solar systems in and around these areas — if yours isn't listed, ask anyway.
Residential
R35
From, per panel
Commercial
R25
Per panel · 100+ panels
Arrays below 100 panels are R35 per panel. Minimum call-out applies. Prices exclude VAT.
A large share of Centurion solar sits on estate homes and townhouse blocks, which changes the job. Access is controlled, roofs are close together, and one contractor visit can cover a dozen households if the body corporate coordinates it. We are happy to work either way — a single home, or a scheduled sweep through a whole complex at a per-panel rate that drops as the panel count rises.
Mature estate landscaping brings birds, and bird droppings are the worst kind of soiling because they block a cell completely rather than dimming it, which can drag a whole string down. Homes within a few kilometres of the N1 or N14 pick up an oily road film that plain rain will not shift. Both need a proper soft-brush wash rather than a rinse.
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
Yes. We quote body corporates and estates per panel across the entire site, which lands well below the single-home rate, and we schedule the visit so all the units are done in one contractor booking.
R35 per panel below 100 panels and R25 per panel from 100 panels, excluding VAT, with a minimum call-out. Larger complex jobs are priced on the total panel count.
Yes. We are used to estate sign-in, proof of company details, working-hour restrictions and site induction at places like Irene, Cornwall Hill and Amberfield. Tell us what your estate requires when you book and we will have it ready on the day.
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.
