Sometimes, solar panels can collect more dust and debris than you’d expect, especially on a big property like this one in Claremont.

We took on the challenge. Some panels needed extra effort to reach, so we used a lift and made sure every surface was cleared. The difference was easy to spot as we worked—clean panels just shine brighter.

Keeping commercial solar panels maintained like this helps keep things running smoothly. If your business has panels that could use a clean, let’s talk about what we can do.

Commercial Solar Panel Cleaning

Getting to every solar panel isn’t always simple, especially when some sit high above tricky rooftops or carports. For this commercial project in Claremont, we took on 2,275 solar modules, making use of a 45' boom lift to reach even the toughest spots safely.

We worked panel by panel, removing the summer buildup so each one could get the most sunlight possible. The difference was easy to see as they started to reflect the blue sky again.

Clean solar panels keep things running smoothly all season. If your building’s panels need attention, we’re ready to help.
