Solar panel cleaning
Dont let dust steal your sunshine away
why clean your solar panels?
Over time, solar panels accumulate dust, dirt, bird droppings, pollen, and pollution—reducing their ability to absorb sunlight. Even light grime can cause significant efficiency loss.
Fact: Just 1.5g/m² of dirt (barely visible) can reduce panel output by up to 5%. In more polluted or dusty areas, output losses can reach 20–30% or more.
benefits of cleaning your solar panels
1
Increased Efficiency
Regular cleaning can restore 15 to 30% of lost energy generation, sometimes even more.
2
More Savings
Clean panels produce more electricity, meaning lower energy bills or more revenue from feed-in tariffs.
3
Longer Panel Lifespan
Built-up grime can cause hot spots, corrosion, or permanent damage. Cleaning helps your panels last their full 25+ year lifespan.
What Are Generation Losses?
Dirty panels generate less power—period.

Why Rain water & Tap Water Aren’t Enough
Rainwater is not a cleaner.
It helps rinse off loose dust but doesn’t remove oily residues, bird droppings, or hard mineral spots.
Tap water is risky.
It contains minerals and calcium that can leave white spots and stains (limescale), which degrade panel clarity and performance.
That’s why we use deionized (DI) water and soft-bristle, solar-safe brushes for a streak-free, chemical-free clean.
