What we never do
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 worth:
R7,096 – R21,289 a year
Payback range: 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.
Highveld 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.
≈13,860 kWh “clean year” yield (~440 W × 18 panels); recoverable band ≈ 1,386 – 4,158 kWh/yr at 10% / 30% loss vs that baseline.

Anton Opperman3 weeks ago“Fantastic service from start to finish. The team communicated clearly, arrived as arranged, and did an excellent job cleaning our solar panels. We noticed a definite improvement in the panels’ output immediately after the cleaning, which shows what a thorough job they did. Professional, reliable, and a pleasure to deal with—I would happily recommend them to anyone looking to improve the performance of their solar system.”
Dalene Bloemhofa month ago“Very professional ONGOING FEEDBACK OF THE PROCESS Punctuous Excellent results Premises left spotless”
Theresa Jurgensa month ago“We had HelioClean clean our 18 solar panels and couldn’t be happier. Hendrik clearly knows his trade – he even tested our water and purified it before starting, so nothing was left behind on the glass. He worked through every panel methodically, without cutting corners, and the attention to detail showed. Friendly and professional from start to finish, and he left the premises just as he found them, clean and tidy. Happy to recommend him.”
Herman Boshoffa month ago“Exceptional service from HelioClean! The team was professional, punctual, and a pleasure to deal with. They cleaned my solar panels, and the results speak for themselves. Their equipment is highly professional and top-notch, and the quality of their work exceeded my expectations. I highly recommend HelioClean to anyone looking for reliable, high-quality solar panel cleaning services.”
Jaco Koninga week ago“Very well organised team. They cleaned my panels while I was at work. Sent me pictures of the pre-clean, mid-clean and after-clean. I was kept in the loop from the time the technician dispatched to my house until he was done with the job. Very easy and convenient. They are trustworthy and professional. I highly recommend them.”

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

The essentials behind every clean — and what we refuse to do to your panels.
Mineral-free water that dries streak-free — no garden-hose white spots that bake onto hot glass.
Soft brushes made for panel coatings. We never pressure-wash panels or scrub with abrasives.
Trained crews with working-at-heights discipline and public liability cover on every visit.
Repeatable SOPs, clear handovers, and before-and-after photos so you know what was done.
Pretoria, Centurion, and nearby corridors — crews who know Highveld dust and access patterns.

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 — 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.
