Qualified electrical contractor
Small to medium-scale solar maintenance in Pretoria, Gauteng & surrounds
A solar system is not fit-and-forget. Panels get dirty, connectors loosen, isolators fail and inverters quietly throttle production. RobCon Electrical services residential and commercial solar systems — cleaning, inspecting and fixing what we find — so your array keeps producing what you paid for.
What solar maintenance includes
- Solar panel cleaning to remove dust, pollen, bird droppings and Highveld grime
- Visual inspection of glass, frames and mounting rails for cracks or movement
- DC cabling, connector and isolator check for heat damage or water ingress
- Inverter status, error logs and production comparison against expected output
- Earthing, surge protection and DB board check by a qualified electrician
- Written feedback on anything that needs attention, with a price before we act
Signs your system needs attention
- Your inverter app shows lower daily production than last season
- Your municipal or Eskom bill has crept up without a tariff change
- Panels look dull, streaked or spotted from the ground
- The system has never been serviced since installation
- You are near construction, a busy road, trees or industrial areas
- Your installer's workmanship warranty requires regular maintenance
Solar panel cleaning is included in every maintenance visit — R35 per panel below 100 panels, or R25 per panel from 100 panels.

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!
