Professional solar panel cleaning in Pretoria & greater Gauteng

For most Pretoria and greater Gauteng homes, a professional clean every 3–6 months is a practical baseline. Suburban roofs often sit at 4–6 months; sites near construction, farms, or heavy bird activity may need cleaning every 2–4 months. Rain helps a little, but Highveld showers rarely rinse baked-on dust the way purified water and soft brushes do. We’ll recommend a rhythm based on your roof, surroundings, and inverter history.

Yes. We use RO/DI purified water, soft solar-safe brushes, and working-at-heights discipline — not abrasives, harsh chemicals, or high-pressure washing on panels. That approach protects anti-reflective coatings and aligns with what most manufacturers recommend. Our crews are trained, insured, and follow clear on-site safety checks before any roof work starts.

No. We clean with reverse-osmosis / de-ionised (RO/DI) water and gentle agitation. Mineral-free water dries streak-free without leaving the white spots that municipal or borehole water often leave on hot glass. That means cleaner panels, better light transmission, and no chemical residue on coatings or frames.

Not always. If we have agreed access — gate codes, a nominated contact, or clear parking and roof access — the team can complete the clean without you on site. We’ll confirm the plan by phone or WhatsApp beforehand, introduce ourselves on arrival, and share before-and-after photos when the job is done. Pets, security systems, and special instructions are best flagged when you book.

Most residential solar cleans take about 1–2 hours, depending on panel count, roof complexity, and access. Bundling exterior windows or glass on the same visit usually adds time but still finishes in one trip. Larger estate or commercial arrays are scoped separately so we can plan crew size and timing properly.

Yes — and that’s the smart default for Highveld dust. A quarterly plan is our recommended option: 15% off from visit 2, priority scheduling, and automatic reminders. Your first clean is billed at the normal single-visit price; we enrol the plan after that visit (you can cancel anytime — future visits then revert to full rate). Biannual plans (10% off from visit 2) are available too.

If you’re not happy with how the panels look after our visit, tell us within 7 days and we’ll return to re-clean free. We document before-and-after photos on every job. We do not guarantee a specific kWh or percentage production lift — every roof, inverter, and weather pattern differs — but we stand behind a professional appearance finish.
