RobCon Electrical is based in Pretoria East, so Pretoria is the area we clean most. We clean rooftop and ground-mounted solar arrays for homes, estates, guesthouses and businesses right across the city, from Waterkloof and Lynnwood through to Montana and Pretoria North. Because we are local, we can usually get to a Pretoria site within a few working days.
Dry Highveld winters leave a fine dust film that cuts output long before panels look dirty
Jacaranda and plane-tree pollen in spring bonds to the glass once dew settles
Ongoing residential development on the eastern edge throws construction dust across whole suburbs
Most Pretoria homes we service run 10 to 20 panels, which takes about one to two hours from arrival to pack-up.

Why Pretoria panels lose more than owners expect
Pretoria sits in a dry winter belt where it is normal to go from May to late September with almost no rain. Over that stretch a film of red Highveld dust builds up evenly across the glass, and because it builds slowly the panels never look obviously dirty from the ground — the loss shows up only on the inverter app, as a summer-to-winter drop that owners tend to blame on shorter days.
Spring makes it worse rather than better. The jacarandas Pretoria is known for drop a fine pollen that sticks the moment dew settles on cool glass, and the first thunderstorms turn that layer into a streaky crust instead of washing it away. That is why we book most of our Pretoria residential cleans for August through October.
How we work in Pretoria
Being based in Pretoria East means short travel, so we can usually offer a slot within a few working days and, for smaller jobs, fit you in around another booking in the same suburb. We arrive with our own water and equipment — nothing is run off your supply — and we clean early morning or late afternoon while the glass is cool, because cold water on hot glass can crack a panel.
RobCon Electrical is a registered electrical business, not a general cleaning crew. While we are on the roof we look over the mounting rails, clamps, isolators and visible cabling, and we tell you if something needs attention. On Pretoria roofs the most common finds are perished cable ties and a sun-damaged isolator cover.
What our clients say
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.
Zander Walters

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
Solar panel cleaning in Pretoria — your questions
Solar panel cleaning in Pretoria is R35 per panel below 100 panels, and R25 per panel from 100 panels, excluding VAT, with a minimum call-out. A typical 12-panel Pretoria home therefore starts at around R420 excluding VAT. Send us your suburb and panel count on WhatsApp and you get a firm price back, not a range.
We are based in Pretoria East, so Pretoria bookings usually get a slot within a few working days, and often sooner if we already have a job in your suburb that week.
Late winter to spring, roughly August to October. That is the end of the dry Highveld season when dust has been building since May, and it is right before the jacaranda pollen and the first storms bake that layer onto the glass. Cleaning then recovers the most output for the summer generation season.
Yes. We regularly work in Silver Lakes, Six Fountains, Woodhill and similar Pretoria East estates, and we are used to estate access rules, contractor sign-in and working around body-corporate requirements. For whole complexes we quote per panel across the full site, which comes in below the single-home rate.
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.
