Solar Panel Cleaning In Sevenoaks

Solar panels in Sevenoaks do need to be cleaned. In the past, some systems were mis-sold under the impression that they are “self-cleaning.” Most solar panels installed in the UK are not self-cleaning.

Keeping your solar panels clean can improve efficiency by up to 30%. Many installers recommend professional cleaning every six months to ensure panels continue operating at maximum performance.

Because solar panels face upwards, they naturally collect dirt and debris. Much of this build-up is not visible from ground level, which is why many homeowners and businesses are unaware their panels are dirty. Over time, pollution, dust, tree sap, pollen, soot, salt, and other fine airborne particles form an opaque layer of grime on the glass surface — significantly reducing energy output.

Why the Correct Cleaning Method Matters

Solar panel manufacturers do not recommend the use of chemicals or detergents.

· Tap water and rainwater alone are not sufficient to clean panels effectively.

· Detergents can leave a microscopic sticky residue that attracts more dirt.

· Hard water can leave mineral deposits and water spots on the glass surface.

Improper cleaning methods can reduce efficiency and potentially cause damage.
