How much does cleaning solar panels improve their output?…read more I had my solar panels cleaned recently by @sudandsqueegie. I had them cleaned only a few months earlier by another company, but I recleaned them because two panels were producing lower output and looked obviously dirty. The other panels did not look like they needed cleaning. I was surprised to see that the cleaning improved the output of all the panels from an average of about 340 Wh per panel to about 540 Wh, an increase of about 58%! The first picture is a drone shot of the panels, showing the two panels that were obviously dirty. The first panel picture shows the output of all panels before cleaning, and the second panel picture shows the output after cleaning. The panel output measurements were taken within 1 hour of each other at around 1 pm. It was a partially overcast day, so the output is usually much greater. However, it shows the amount of improvement possible with simple cleaning of the panels, despite them not appearing obviously dirty to the naked eye. It turns out the two panels that looked obviously dirty had cracks in the glass surface, and most of the discoloration was dirt that had seeped underneath the glass coating and could not be removed by cleaning. Surprisingly, not only did the surface cleaning of the two "dirty panels" improve, but it also improved the other panels that did not look like they needed cleaning! The original company that did the cleaning used a brush on a long pole to drip deionized water onto the panels. @sudandsqueegee used a long pole with two rotating brushes, which seemed to be more effective. They were very efficient and professional in their work. I recommend them highly.

Jeff was punctual, friendly, honest and gave us a great price. We made an appointment for early the next week. Communication w Jeff was easy and responsive.

My father was very happy with the re screening by Jeff. I always try to patronize small family run businesses instead of the big box companies! I encourage anyone who needs their windows re screened to give Jeff a call at Socal Windows. 100% Socal Windows

Clean Clear Services SD did a great job with our partial roof wash and solar panel cleaning. We had…read morethe front 1,000 sq. ft. of the house washed, along with the solar panels on our two-story home, and the difference was incredible. The roof had noticeable staining from the palms and surrounding vegetation, and after the cleaning it made a huge difference in the overall appearance of the house, especially as you approach from the front. Everything looks much cleaner, brighter, and better maintained. The service was professional, the results were exactly what we were hoping for, and the improvement was very noticeable. I would definitely recommend Clean Clear Services SD for roof washing and solar panel cleaning.

**15% immediate increase in solar production**…read more I had the pleasure of working with Jason Waldie of Clean and Clear Solar and Window Cleaning Services to clean my 18 solar panels, which had not been cleaned since 2021, as well as three skylights. Jason came highly recommended and I can absolutely see why. From start to finish he was professional, thorough, and took the time to explain the entire process. He answered every question I had and even provided before and after photos that speak for themselves. After the cleaning I measured a 15% increase in my solar production, proof that keeping panels clean really does make a difference. Jason's attention to detail was impressive and he clearly takes pride in his work. It is obvious that Clean and Clear cares about delivering top quality results. This experience has made them my go to for any exterior cleaning needs and I would not hesitate to recommend them to anyone. If you have solar panels, do yourself a favor and get them cleaned at least once a year. You will see the difference in both appearance and performance.

I used Shine Bright San Diego to clean my paving stone patio, getting rid of in-ground dirt,…read morediscoloration, weeds etc. I was serviced by Brooks, a very friendly and engaging gentleman. Here are the pluses and minuses of my experience. Pluses: * Rapid and courteous response to my initial request * Quick turnaround for an appointment * Quoted me a 2 hr arrival window, which they met. * Affordable service. * Patio is nice and clean and he cleaned splashes from the adjacent windows/ doors. Minuses: * I had told them about my pool right next to the patio, but Brooks didn't take any special attention to prevent some dirt and sand from entering the pool (e.g, putting down plastic film). Nor did they provide a method for cleaning it afterwards, which led to clogging the pump intake line, requiring a lot of effort on my part to clear. * On the patio itself, I needed to use a blower to remove residual stuff that the power wash didn't deal with. Ideally, they would have done that as part of the service. I would give them 3.5 stars if that was an option: I feel 3 is too harsh. 4 is probably a bit generous given what I needed to do afterwards. So, be wary if you have a pool nearby that they offer you a solution to prevent crap getting in it.

Review Update: After…read moremy initial review, Eric (the sales rep) and Matt (the owner) of Sunline personally reached out to me and was apologetic about the situation. They sent Travis out promptly, who is their electrician where he found that the issue was resolved by replacing a faulty 40-amp breaker that was intermittently providing the necessary voltage, even though measurements initially appear correct. While the breaker issue caused real inconvenience and unexpected costs on my end, the owner was responsive and showed willingness to smooth things over to work toward a resolution. I also want to highlight that the panel upgrade and solar/battery installation itself was clean and well done. The workmanship that Eddie, Manny, Christian and Jamie performed had overall met my expectations, and once the issue was identified, Sunline did step in to correct it. No project is perfect, but how a company responds when problems arise matters a lot. In this case, Sunline's owner and Eric was engaged, responsive, and made a sincere effort to make things right. As an engineer, and after witnessing the symptoms and corrective actions firsthand, I believe the breaker issue was likely a manufacturing defect, and it was unfortunate that it occurred during the holidays. That said, based on how Sunline handled the situation, the overall quality of their work, and the value they offer, I would recommend them and plan to continue using them for future needs.

I reached out to a couple other businesses on Yelp, and Terry was the first one to respond! He was able to quote me a flat rate based on the number of panels we had, and he was very responsive. I waited for other businesses to respond to compare prices, and Terry is by far the most reasonably priced out of the several other businesses that responded. He was very communicative and flexible with scheduling. He showed up on time and was very professional and informative. After answering my questions, he got straight to work, and finished in a timely manner. I really appreciate the before and after pictures, as well as offering reminder texts when it's time for the next cleaning. He also offers bird netting to protect your panels, and he offered a very generous bundle price if we decided to add on the bird netting during our next cleaning. Overall, Terry was professional, communicative, straight to the point, and it's obvious that he takes a lot of pride in his work. I will be definitely be recommending Veteran Solar Panel Cleaning to my family and friends! :)

I received a variety of quotes, all of the place with price. Terry had the best reviews combined with a solid price and availability that fit my schedule. He did an excellent job cleaning my panels and since his date of service my panel system has had its two most productive days yet. A 20% increase pre-service. His communication was solid, no nonsense in person, showed photos of before and after. During the quote process, another business with ZERO reviews gave me a quote completely out of bounds and I gently suggested as a new business he run some specials to build up reviews. He became indignant and said "Good luck paying for lower quality service". My response was good luck getting any customers. I will hire Terry again in the future. Veteran's Solar Panel Cleaning is highly recommended!

It looks like previously, we had our bird guard lazily put up with huge gaps that did not keep the pigeons away. We agreed to not only solar panel cleaning, but also redoing the bird proofing. I gotta say, I love the transparency and the quality of their work. Curtis was super kind to my wife and explained everything to her. He would show updates through video and pictures so you're always updated on what's happening. They were so nice to even provide a "neighborly discount" for the solar panel cleaning, since we decided to get the bird proof done. For the value, I would say go with it. Don't go with really cheap bird proofing because that really came to bite us at the end. The cost was very reasonable. Trust me, these guys know whats up.

He communicates well, shows up when he says he will, and does a thorough job cleaning everything up when he's done.

But not in this case, Curtis absolutely earns the five stars and provides top-notch service and he also goes the extra mile.
