We had our solar panels cleaned by The Solar Cleaning Pros out of Willows and the gentleman did an excellent job. He was here early and on time and explained to us the process. The job only took about an hour to complete and he recommended a yearly cleaning so now we’re all set up for next year. Excellent work done, friendly people and great rates. HIGHLY recommended!

Wife wasted her Saturday waiting for another company to clean them. She called that other company 4 times. And not even so much as a return call. 🙄 they did call this evening 2 days later. So while she waited searched for another company. She found Solar cleaning pros. Not only did this young show up on time. He did an amazing job. Solar pro. You get 5 plus stars.
