Do Perth solar panels need cleaning?

Rain does most of the work in winter, but a long dry summer near the coast or a busy road can cost you 5 to 10%.

Panels clean themselves in rain, so most homes never need a professional clean.

When it helps - Coastal suburbs with salt spray - Homes near major roads or building sites - Flat-mounted panels where dust settles

How to tell Compare your daily readings with the quoted estimate in your account. If summer output is well below what we promised on clear days, open a service request and choose Panel clean.
