Warranty-Safe 0-TDS Solar Panel Cleaning in Cape Town
Rain does not clean coastal solar panels — it turns sea salt, pollen, and red dust into baked cement along the bottom frame lip of every panel, triggering bypass diodes and slashing your inverter kWh yield by 12–25%.
- R35 per panel when bundled with window cleaning (or R55/panel standalone, min R750)
- 100% compliant with Canadian Solar, JA Solar, Longi & SunPower warranty rules
- 000 ppm de-ionised water prevents mineral scale hot-spots on anti-reflective glass coatings
- Early-morning cool-glass washing schedule to prevent thermal shock on hot summer days
- Visual check for cracked cells, loose MC4 cables, and bird nesting under arrays
How Much Eskom Savings Are Salt & Dust Stealing From Your Solar Panels?
In Cape Town, sea salt mist, red summer clay dust, and bird droppings bake onto glass PV modules. Because panels are wired in strings, shading or crust on even 15% of a panel drags down the entire string's MPPT output.
Warranty Rule: Never let anyone use high-pressure washers, borehole water, or dish soap on solar panels. We use 000 ppm de-ionised water and a soft solar-certified brush.
Why Hosepipes, Borehole Water & Pressure Washers Ruin Solar Panels
Spraying municipal or borehole water onto warm solar panels leaves mineral deposits that block photons and create localized thermal hot-spots. High-pressure washers cause invisible micro-cracks in silicon cells and breach perimeter frame seals. Our low-pressure 000 ppm pure-water soft-brush method is the exact protocol specified by tier-1 panel manufacturers.
Twice a Year (Inland) or Quarterly (Coastal)
In Durbanville, Bellville, and Constantia, cleaning in September (post-pollen, pre-summer peak) and February (mid-summer dust) keeps generation at 98%+. Within 3 km of the ocean (Blouberg, Sea Point, Camps Bay, Muizenberg), quarterly salt removal pays for itself multiple times over in recovered Eskom units.
