Business, estates & complexes
R25 per panel for arrays of 100 panels or more
On a large array, soiling is not cosmetic — it is lost revenue every single day. RobCon Electrical cleans commercial and industrial solar installations across Gauteng and surrounds: warehouses, factories, retail centres, hospitals, office parks and body corporates. One per-panel rate, with minimal disruption to your business while our teams are at work.
Sites we clean
Warehouses & distribution
Large low-pitch roof arrays cleaned in planned sections so operations keep running.
Factories & industrial
Sites near dust, fallout or mining activity where soiling loss builds up fastest.
Retail & shopping centres
Minimal disruption to your business while our teams are at work.
Hospitals & healthcare
Quiet, low-disruption cleaning around critical operations and access control.
Office parks
Multi-building portfolios quoted as one job with a single per-panel rate.
Estates & complexes
Common-area and per-unit arrays handled together, with one invoice for the estate or complex.

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!
