What dirty panels may cost you
On the Highveld, dust on the glass often knocks 10–30% off what your system could produce. For a setup your size, that lost power is roughly worth:
R7,096 – R21,289 a year
Typical payback: about 1–4 months at this clean price versus leaving that power on the table for a year.
Estimates only; every roof differs. We use sensible Pretoria sunshine and local household electricity steps — tweak below if you know yours.
Dry-season dust stacks up fast. Most of our customers clean every 6 months. We take a limited number of jobs each week — book early for the slot you want.

Visual proof
Soiling losses vary by site, but independent studies and field cases consistently show that accumulated dirt reduces solar output.

Research and real-world pilots show that dust can take a measurable bite out of solar production. The result for your roof depends on local dust, weather, panel angle, and time since the last clean.

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.
See the Gauteng cleaning guideYes. 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.
Compare DIY and professional cleaningNo. 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.
Why we use RO/DI waterNot 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.
