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.

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.

I am incredibly impressed with Decoration Dash. From the initial inquiry to the final install,…read moreeverything was seamless and stress-free. First, their communication is top-tier. They provided a quick response to my quote request and were easy to communicate with throughout the entire process, answering all my questions promptly. The price they quoted was more than reasonable, especially for the quality of work. There were no hidden fees or surprises--just a straightforward, fair price for a professional job. The installation crew was efficient and the final result is stunning. The light quality is fantastic--bright, vibrant, and evenly spaced. The color (we chose classic warm white and red) is exactly what we wanted and looks so cohesive and elegant. I highly recommend Decoration Dash to anyone who wants a gorgeous holiday display without any of the hassle. We've found our permanent light installers!

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.

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!
