Gauteng
Midrand sits between Pretoria and Johannesburg and mixes large residential estates with serious commercial and warehousing stock — both of which we clean. RobCon Electrical handles everything from a 12-panel home in Midstream to multi-hundred-panel warehouse roofs, scheduled around your operating hours so nothing stops.
A Midstream client measured 32% higher generation after a professional clean by our team.
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.
Midrand is unusual in that a single suburb can hold a 12-panel Midstream home and a 600-panel distribution-centre roof. We clean both with the same method and the same team, with commercial work planned so your operation keeps running while we are on the roof.
Anything within sight of the N1 through Midrand picks up a greasy traffic film that binds dust to the glass. It is the reason Midrand panels often look worse than the rainfall record suggests they should, and the reason a rinse-only approach fails here — the film needs a soft brush to lift it.
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 clean multi-hundred-panel commercial and warehousing roofs across Midrand at R25 per panel from 100 panels, or R35 below, excluding VAT, planned around your operating hours with minimal disruption while our teams are at work.
It depends on how soiled the array was. One Midstream client measured 32% higher generation after a professional clean by our team. Panels near the N1 or a construction corridor tend to show the largest gains.
Every 6 to 12 months for most homes, and closer to every 4 to 6 months for commercial roofs near the N1 or the Allandale and Olifantsfontein development corridors, where road film and construction dust build up faster.
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.
