This is the first time to have my solar panels clean after 8 years. I called Solar panel cleaning specialist here in Rancho Cucamonga and set up an appointment with Joshua. Joshua arrived on time, very nice guy to talk to and get to know him more about his job. Joshua did a good job over all. I will definitely call him again in the near future. Great service and job well done. I'm happy with this company. Less

Josh arrived on time and did a marvelous job of cleaning our solar panels. After checking our inverters prior to cleaning and then again after cleaning, the output increased by one-third (950 watts to 1465 watts). We try to hose them off ourselves periodically, but having Josh clean them was just amazing. We highly recommend his service to anyone who wants to see there solar output increase and save even more money. We will be regular customers going forward for sure. Less

Josh does an amazing job! I have him come out every 6 months to improve my panel output. You immediately see an increase in production. Josh makes it easy to schedule appointments and always shows up. I do not hesitate referring him to my family, friends and clients. Less

Awesome service. My panels are looking great and production is at its max potential. Joshua was very professional and punctual. Panels should be cleaned at least once a year here in SoCal and I will definitely be calling Joshua again. Highly recommended. Less

This is our first time ever to have our solar panels cleaned. Josh came highly recommended by a relative of mine. His work did not disappoint. He is very thorough and honest, his work speaks for itself. Not only did he clean the panels, he also cleaned up the mess left from the roof. He showed us before and after photos of the work he did. I have to say, the solar panels look way better than it did when it was new since we moved in. I highly recommend Solar Panel Cleaning Specialists and would give them 10 stars if I could. Less

Joshua has been cleaning my solar panels for 2 years now. Great service, dependable and does a great job overall. Trustworthy and honest. Such a nice guy too! Well worth it ! Would highly recommend him to anyone. Less

I've used Joshua a couple of times for solar panel cleaning. He is always on time, respectful and offers a reasonable cost. I have 52 panels and after they're cleaned, solar productivity always increases. Definitely a good choice!!! Less
