For optimum performance we recommend that your panels are cleaned on an annual basis.

It’s important that you do NOT pressure wash your solar panels – instead, we recommend using a professional window cleaner.

We recommend that your panels are cleaned only with a soft brush and de-ionised water or rainwater.

*Please do not use detergent of any kind.

For REC panels, please refer to a separate cleaning guide, which is available in our Download section.
