Why clean solar panels?

A solar panel can only convert the light that reaches its cells. In Gauteng, dry winter months leave a fine layer of dust, spring brings pollen, and birds love a warm, flat roof. Rain alone doesn't wash this off properly. It tends to pool the dirt along the bottom edge of the frame, where it bakes into a crust.

Load-shedding has made solar a serious investment for homes and businesses across Pretoria and Centurion. A clean is a small cost compared with what a dirty array loses in output over a year.

Gentle by design

We never blast solar panels with high pressure. That can damage the anti-reflective coating, push water into the frame seals, and even void the manufacturer's warranty. We use low pressure, soft brushes suited to glass, and clean water. We also clean in the early morning or late afternoon whenever possible, so cold water never hits hot glass.

How often?

For most Pretoria and Centurion homes, cleaning two to four times a year keeps output where it should be. Panels near dirt roads, construction, farmland or trees where birds roost may need more frequent cleans. If your inverter app shows output falling on clear days, the panels are probably due.

Our process

1. Safe access

   We check the mounting, roof condition and safe working routes.

2. Dry dust-off

   We loosen heavy dust and debris first so it does not scratch the glass.

3. Soft wash

   Soft brushes and low-pressure clean water, with no harsh chemicals.

4. Rinse & check

   A spot-free rinse, then a visual check of frames and cabling.

Solar Panel Cleaning: FAQ

Can you pressure wash solar panels?

Not with high pressure. It can damage coatings and seals. We use low pressure, soft brushes and clean water designed for glass.

How much efficiency do dirty panels lose?

It varies with how dirty they are. Heavy dust, pollen and bird droppings can reduce output by up to around 30%.

Do I need to switch my system off?

We follow your installer's guidelines. For most systems we isolate the array before cleaning, and we will talk you through it on the day.
