Solar Panel Cleaning

Did you know that dirty solar panels can lose up to 25% efficiency! Now that you’ve gone to the effort and cost of installing solar panels, make sure you’re getting the maximum output from them.

On a typical domestic solar installation ladders are not required due to the use of telescopic water fed poles. These WFP (water fed poles) use clean water and no chemicals to ensure no corrosive harm can occur on the panels.

Maintenance through cleaning will ensure a higher solar power output is maintained throughout the year.
Price assumes that the panels are located no more than 10m above the ground with easy access. We will check this with you before we quote

Why clean panels?

On a sloping roof panels will automatically be cleaned by the rain; in addition the glass on the panels is self-cleaning glass.

However, dirt will tend to accumulate in the bottom corners of the panels and as a precaution we recommend the panels should be cleaned annually. This will ensure efficiency is maintained and output is not reduced. Dirt on the glass covering the solar cells will absorb sunlight and as a result less light will penetrate through to the solar cells.
