When the owners of Crown Estate noticed a drop in the performance of their rooftop solar system, they suspected the panels had become heavily coated with dust and debris. With more than 600 panels installed across several large buildings, arranging traditional cleaning would have required roof access, safety equipment, and significant downtime.

They contacted Drone Cleaning Australia for a faster and safer solution.

​

Using our specialised cleaning drone, the team carried out a full aerial solar panel wash using purified water and a soft cleaning system designed specifically for photovoltaic panels. Operating entirely from the ground, the drone safely cleaned the entire array without anyone stepping onto the roof.

​

At the same time, a thermal inspection was conducted to check for hotspots, damaged cells, or faulty connections that could reduce efficiency.

Within hours the panels were clean and performing better, and the client received a detailed thermal report highlighting two panels that required maintenance.
