Solar Panel Roof Cleaning in Vancouver WA – Safe Methods That Work

Solar Panel Roof Cleaning in Vancouver WA – Safe Methods That Work

If you have solar panels on your roof in Vancouver WA, you probably already know how fast they get covered in moss, algae, and dirt. What many homeowners don’t realize is how much that buildup hurts their energy production.

I’ve been cleaning roofs since 2020 (ProSoaks since 2022), and solar panel cleaning is one of the jobs I enjoy most because the results are so dramatic.

Dirty solar panels can lose 20-30% of their efficiency in our wet climate. Moss and algae hold moisture and block sunlight. The safe way to clean them is with low-pressure soft wash. We never use high pressure or harsh scrubbing that could damage the panels or void the manufacturer warranty.

We carefully apply the right cleaners, let them work, and rinse thoroughly so we don’t leave any residue. We also clean the roof around the panels at the same time so moss doesn’t grow back and spread onto the panels.

Real Vancouver WA Example

A homeowner in Battle Ground had solar panels that were covered in green moss on the north side. His energy production had dropped noticeably. We did a gentle soft wash on both the panels and the surrounding roof. Within a week his production numbers went back up significantly. He was shocked at how much difference it made.

We recommend cleaning solar panels every 12–18 months in Vancouver WA, or sooner if you notice heavy buildup. We always work carefully around the panels and never use anything that could scratch or harm them.
