Reverse-osmosis and deionised (RO/DI) water is the backbone of how we clean. Here's how it compares in plain language.
| Topic | RO/DI purified water | Harsh chemicals | Untreated tap water |
|---|---|---|---|
| Coated solar glass & warranties | Gentle agitation with water formulated to leave no mineral film — aligned with how manufacturers expect panels to be washed. | Risk of damaging anti-reflective coatings or conflicting with manufacturer care guidance. | Dissolved minerals can dry as spots and build up over repeat visits. |
| Scratch risk | Soft brushes and controlled flow — no grit dragged across the glass. | Some products need aggressive scrubbing or tools that aren't panel-safe. | Particles in cloths or squeegees can still scratch if not managed carefully — we standardise kit and technique. |
| Streak-free windows | Deionised rinse dries clean — excellent for high glass and shopfronts. | Residue and fumes; often more rinsing and runoff to manage. | Hard water marks are common without filtration. |
| Water-wise mindset | We use what the job needs — pure water does more work per litre than flooding the roof with untreated water. | Chemical use adds disposal and environmental considerations. | Repeated heavy rinsing to fight spotting uses more volume overall. |
Our cleaning process
The same high standard on every job — from a single home to a multi-building estate.
We assess roof and glass access, weather, and your array before we start.
RO/DI water and soft brushes — no abrasives, no pressure washing on panels.
Thorough rinse and a careful pass so every panel and pane meets our standard.
Before/after photos where useful, then a clear wrap-up so you know the job is done.

Straight answers — no jargon.
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. Many customers turn a first clean into a quarterly, six-monthly, or annual plan. Plans keep soiling from quietly cutting output between visits, and they typically include priority scheduling plus better recurring rates. We’ll suggest an interval that matches Highveld dust, bird activity, and how your system has been performing.
Yes. Exterior window and glass cleaning pairs well with a solar visit — one insured crew, one trip, shared setup time. Request a custom window quote via WhatsApp or the contact form and we’ll price the glass for your property, then schedule both together where practical.
We plan around your site — early mornings, after-hours, or quieter windows where possible — and use safe, low-disruption methods. Access routes, parking, and any restricted zones are confirmed in the quote so day-to-day operations stay as uninterrupted as we can manage.
Yes. We quote recurring cleans for sectional titles, office parks, schools, and warehouses. You get a clear scope, agreed visit rhythm, and handovers or reporting where trustees or facilities managers need them — useful for budgeting and consistent array performance across multiple roofs.
