How often should solar panels be cleaned?

In Cape Town we recommend every three months. Coastal dust and salt spray build through the dry summer (November–March) and tree pollen peaks in spring, so a quarterly cycle keeps output consistently near peak.

Does rain clean solar panels?

Only partially. Summer rain rinses loose dust but leaves behind bonded grime, pollen film and mineral residue — and it often dries into streaks that shade cells. Rain is not a substitute for a proper clean.

Is the cleaning process safe?

Yes. We use telescopic water-fed poles with soft brush heads and pure deionised water — no abrasive chemicals, no pressure washing, no walking on panels. We are fully insured and follow working-at-heights protocol.

How long does it take?

A typical 10–15 panel residential system takes 45 to 75 minutes including the inspection and photo report. Commercial sites are scheduled after a free survey based on panel count and roof access.

What areas do you cover?

All of Cape Town and surrounding areas, including the Southern Suburbs, Northern Suburbs, Atlantic Seaboard, City Bowl, Blaauwberg, Durbanville and the Helderberg. Outside these areas, ask us — we often can.
