At Eco Solar Clean, we recently completed a professional clean on a 90-panel solar installation located on a busy main road.
Why Dust, Pollen, and Bird Droppings Are a Problem
Many people assume that rainwater will keep their solar panels clean, but in reality, panels exposed to busy roads and open areas gather a lot of dust, pollen, and bird waste that rain alone can’t remove.
Dust and pollen form a fine layer over the panels, blocking sunlight and reducing energy output by 5–15%.
Bird droppings are even more damaging. They are acidic and can bake onto the surface, causing hot spots that can lead to permanent damage if left untreated.
Without regular cleaning, these contaminants can dramatically lower energy production and shorten the lifespan of your solar panels.
Our Cleaning Process: Deionised Water for a Streak-Free Finish
For this 90-panel system, we used pure deionised water applied through specialised equipment designed for solar panels.
Deionised water is the safest and most effective method for solar panel cleaning because:
It leaves no streaks or chemical residue.
It lifts and removes dirt, dust, and grime without abrasive scrubbing.
It protects the surface coating of the panels while restoring maximum energy absorption.
Using deionised water ensures a spotless finish that helps panels perform at their best, without any risk of damage.
Why Regular Solar Panel Cleaning Matters
Solar panels located near main roads are exposed to much higher levels of dust and pollution.
Add seasonal pollen and bird activity to the mix, and you have a recipe for rapid performance loss.
We recommend solar panel cleaning at least once every 6 to 12 months to keep your system running efficiently and protect your investment.
The benefits of regular cleaning include:
Higher solar energy production
Protection against permanent surface damage
Longer panel lifespan
Maintaining manufacturer warranties that require regular maintenance
