  • "I called Guru solar cleaning to wash my windows, as I was selling my home in Long Beach. (So many companies to choose from, and I got lucky!) These guys were exceptional! My 10 yr old windows, screens, and tracks looked brand new! I also had them pressure wash my brick patio, which was offered upon arrival, and it looked fantastic! Great service and prompt, efficient professionalism! I would hire them again in a second! Fair pricing as well."

  • "I would highly recommend Guru Solar Cleaning for solar panel cleaning. Looking for a new vendor, I came across Guru and Sal. Sal was super easy to work with. Very professional. Great communicator via phone or text. I am very particular with my vendors, so I gave Guru a shot at a very large commercial solar cleaning project with 1000+ panels. I had no issues or complaints about the outcomes. The team did a really great job. The before and after photos and drone videos that Sal provides with his service are a really great addition. I very much recommend and will be using Guru for additional commercial projects. Their pricing is very comparable and fair. Thank you Sal for your great hard work.”

  • “I like to support small businesses and when I read the reviews I scheduled an appointment to have Sal clean my solar panels. One set of panels which were over 14 years old and never cleaned. Reviews are spot on. Sal is terrific. Panel are shiny again. My meter shows energy going back to the grid on a summer day and air conditioning on. He showed me before and after pictures. I was so impressed I made an appointment to have him pressure wash my garage floor and driveway next week.”

  • "I live on a street with tall pine trees. Needless to say, my roof, gutters and solar panels routinely get inundated with pine needles, pollen and dust. Guru gave me a reasonable price, showed up on time, and went above and beyond to make sure that my 28 panels were cleaned and my gutters were taken care of at the same time; all within a single afternoon. Definitely money very well spent and I highly recommend Guru to anyone."

  • "I asked Sal to clean solar panels, power wash my driveway and back patio, and clean my larger bay windows. I first noticed and was impressed with his quick responses and his punctuality. He was on time for the quote and for the job. The quote came in a little higher than I expected, but I thought to give his services a try and see if they really would make a difference in the looks of my house. They did. The solar panels are shining, the driveway and patio are much brighter, and the windows, inside and out , are flawless. Sal is personable and very conscientious about the work he does. You won’t be disappointed with Guru Solar Cleaning."

  • "We love working with Sal! We had him do our gutters a while back, and this time we came and did our windows and solar panels. It was great! Sal is super easy to work with, very professional, and great value. His work was super detailed and thorough - and the windows and panels looked great! The windows were so clean... that about 1 week later, one of our friends walked face-first into one because they thought the sliding door was open. (true story!) We're looking forward to continuing to work with Sal!"
