Tim came out and washed my solar panels and they have never been so clean and now I have them on a regular schedule for every four month to come keep them clean. And he’s going to come back and power wash my driveway.

Tim is a nice guy and did a good job cleaning my panels quickly. I've only had them one year and the production had already dropped 20% because they were dirty. Tim got me back to full production. He arrived a little late but let me know ahead of time and also gave me a mini gutter cleaning.
