Solar panel, solar geyser and window cleaning in Fish Hoek
Solar & Window Clean is a mobile cleaning service based in Fish Hoek, run by Cobus Bester. We clean solar panels, solar geysers and windows on single- and double-storey homes, shopfronts and offices across the South Peninsula, Atlantic Seaboard and Southern Suburbs.
Monday to Saturday, 08:00–17:00. Cobus aims to reply to WhatsApp messages within an hour during these hours.
What does Solar & Window Clean do?
We clean three things: solar PV panels, solar geyser (solar water heater) collectors, and windows and glass.
Solar panels
We lift dust, salt film and bird droppings with purified water and soft brushes. We never stand on your panels.
Solar geysers
We clean the collector glass on solar geysers, so dirt doesn't block the sun. We don't do plumbing work.
Windows and glass
Homes, shopfronts and offices, single- and double-storey. Purified water dries without mineral spots or a soapy film.
What we don't do: paving or driveway washing, roof repairs, plumbing or electrical work, or anything above double-storey. Cape Town's Water By-law doesn't allow hosing down paved areas with municipal drinking water without the City's written permission.
Why does summer matter for solar panels and geysers in Cape Town?
Because Cape Town gets most of its rain in winter, so your panels and solar geyser glass get the fewest rinses when the sun is strongest.
Not every roof needs a clean, though. Steep panels that get a good winter rinse may not need us yet (Canadian Solar). Send Cobus a photo, or read when cleaning helps, and when it doesn't.
Why clean solar panels and windows with purified water?
Purified water has almost no dissolved minerals, so it dries without mineral spots and needs no soap or detergent (Unger).
The tap water in our area is soft (City of Cape Town; USGS), but it still carries minerals that dry as spots. We use pure-water equipment from a specialist South African supplier.
Purified water: filtered by reverse osmosis.
Soft brushes: no scrapers or abrasives on panels or collectors.
Water-fed poles: for cleaning glass from the ground.
No soap or detergent: no soapy film left behind.
Never on your panels: we never stand or walk on panels or geyser collectors.
