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.

On the day of the window cleaning the owner texted that he was on his way. Upon arrival Jeremy got right down to business, starting with the outside of the house while I moved objects on the inside so he could get to the windows easily. We have about 35 windows, plus two sliding glass doors in our two story house. The job was finished in about 3 1/2 hours, the timeframe mentioned upfront. The windows, screens and window tracks are spotless. He even cleaned the little windows on the garage doors. Spotless clean-up; after the work was done there was no evidence he was even here! I'm a believer in using small businesses when possible and Jeremy exemplifies the quality, professionalism and caring desired. Great work, I highly recommend Wonder Windows for your cleaning needs!

I actually think it was his day off and he was moving at the time! Jeremy is very professional and his process was quiet and tidy. No running water, splashing or mess that I had anticipated. Within hours, our windows sparkled and the screens were so clean, it looked as if they weren't even there! Jeremy's bill was exactly as he'd estimated over the phone and I couldn't be happier with our choice. His name and number are now in my phone for future window cleaning and knowing his work ethic, I won't wait to schedule. I highly recommend Jeremy of Wonder Window & Cleaning!

Sometimes honesty isn't always the best policy!!…read more I told them my house had just been painted so they charged me extra to scrape off paint overspray. $600 to be exact!!! I assumed they did a good job and tipped the guys well. Then I noticed ALL the paint overspray was still there. And then I remembered that I never saw them use a ladder and I never saw either of them scraping any paint with a razor blade. My honesty did NOT pay off. So I wrote back to them explaining the situation (with some of the pics you see here) and they apologized and set up a "touch up" appointment. That's fine. I mean it's more time that I had to spend waiting for them except....THEY NEVER SHOWED UP! And when I called to ask where they were, they started backtracking. "How many windows are we talking about"? "Did the painters use masking tape?". I'm like "Of course they used masking tape and anyway...WHERE ARE YOU???" So that starts an email thread where they tell me that scraping paint off would take more time and that I would have to pay them more money. I ALREADY PAID YOU MORE MONEY TO SCRAPE THE PAINT OFF!!! $600 to be exact!!! They're now telling me that they didn't realize now much paint needed to be scraped off. Well, look for yourself. Does that look like something they should charge me MORE money for, or something they should have cleaned off in the first place. It's hard to take pictures of stuff on windows but I did my best. Save yourself the HASSLE and use a different company. These people don't know how to run a business, they don't keep their word, they don't show up and they just are not good peeps. EPILOGUE: Well, you can tell from his long, rambling response that he's lying. It's kinda like Walter White in Breaking Bad whenever he tried to lie. He just went on and on. But I know the truth. Had I not told them my house was just painted, I would have gotten the same service for less money. They used my honesty against me and that pisses me off. I'm old enough to remember a slogan that businesses of all kinds used to use. And it's a simple one: "The customer is always right" Not anymore. So what can you do? Fight back. Write an honest review. Demand your money back (In the end, the credit card company sided with me and I got a FULL refund) . Remember YOU have the power. You're not the little guy; You're the customer. And the customer is always right!
