No Dirt Just Power
Keeping your solar panels clean isn’t just about appearances – it’s a smart way to protect your investment, boost performance, and save money long-term.
Why Should You Clean Your Solar Panels?
Maximise Energy Efficiency
Dirt, dust, bird droppings, and pollution can block sunlight from reaching your panels. Even a thin layer of grime can reduce energy production by 10% to 30%.
✅ Clean solar panels = more power generated = lower electricity bills.
Improve Your Financial Return
If your system is grid-tied or under a feed-in tariff, dirty solar panels generate less energy – and that means:
-
Lower monthly savings
-
Less income from energy sold back to the grid
-
Slower ROI (return on investment)
🔧 Regular cleaning keeps your system performing at its financial best.
Prolong Panel Lifespan
Contaminants like dust, mould, and bird droppings can cause:
-
Long-term corrosion
-
Hot spots from uneven light absorption
-
Glass damage or staining
By removing these risks early, you help your system last 20–25+ years, just as the manufacturer intended.
🌧️ Why Rainwater or Tap Water Isn't Enough to Clean Your Solar Panels
1. Rainwater Leaves Dirt Behind
Rain doesn’t fall clean — it carries airborne pollutants, pollen, dust, and even acidic compounds that can settle and dry on your panels, leaving behind:
-
Dirty streaks
-
Mineral spots
-
A sticky residue that attracts more grime
🧼 Result: Rain actually contributes to panel buildup over time.
2. Tap Water Causes Hard Water Stains
South African tap water often contains high levels of minerals like calcium and magnesium, especially in hard water areas. When tap water evaporates on your panels, it leaves behind:
-
White limescale spots
-
Mineral residue that reduces light absorption
-
Long-term corrosion if left untreated
💧 Result: Tap water can damage your panels and reduce performance.
3. Neither Removes Tough Contaminants
Rain or hose water won’t effectively remove:
-
Bird droppings
-
Oily residue
-
Mould or mildew
-
Sticky plant matter (like tree sap)
These require pure, filtered water and professional-grade brushes to be safely removed without scratching the surface.
Our Cleaning Process: Pure, Professional, Proven
We use a Reverse Osmosis (RO) water purification system to clean your solar panels without the use of any harmful chemicals. This method guarantees a streak-free, spotless finish with no residue that could attract more dirt or damage the panels.
Why Reverse Osmosis?
Reverse osmosis pushes tap water through multiple filtration stages, removing:
-
Minerals (like calcium & magnesium)
-
Ions
-
Chlorine
-
Organic impurities
This results in ultra-pure water, perfect for cleaning solar panels safely and thoroughly.
