Solar Panels are a large investment in your home!

Solar Panels in rare instances are ‘self cleaning’, but in particularly dry areas such as Sydney, or where panel tilt is minimal, dust and other substances such as bird droppings can build up over time and impact on the amount electricity generated by a Solar Panel.

Dust, Lichen Mould, Grime and bird poo doesn’t need to cover an entire panel to have an adverse effect. This is where cleaning solar panels may have to be done. And for the longer term, you may be asking “how often to replace a solar panel?”

Safety first  for cleaning  solar panels – follow the procedure in your manual for shutting down the system before commencing cleaning.

Clean solar panels from the ground

For safety reasons, it’s often best for us to clean your panels from the ground if possible. Our designated ‘Soft Wash’ Brushes on Carbon Fibre poles being water fed through our specialised filtration system delivering ‘Pure Water’ to lightly agitate the surface and remove the offending matter.

Off we cannot access the Panels from the ground we will assess the situation and if safe to do so we will access the roof and clean them from there.

Optimally time the cleaning of the solar panels

We often try and advise our clients to clean solar panels in the winter months or on an overcast day, early in the morning or in the evening. If the weather is too hot and the sun is beating down on the panels, any water used can quickly evaporate and dirt will become smeared.

Early morning can be a particularly good time for cleaning as dew that has settled on the panels overnight will likely have softened grime.

Materials and methods we use for cleaning solar panels

If the panels are dry, before tackling the modules with water, we will brush off any loose materials first – this will make cleaning easier and faster.

We DO NOT use any metal objects or harsh abrasive products for removing any dirt or materials. Scratching the glass on a solar panel can affect its performance as scratches will cast shadows. We do not use any detergents or soaps, just our ‘Pure Water System’

Using detergents can streak the glass of the panel, Use of abrasive powders also risks scratching the panels this is why we don’t use any soaps, detergents or abrasives.

Given the nature of good quality solar panel glass, pure water and a little light scrubbing with our specialised brushes should remove the most stubborn grime.
