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.

From the initial estimate through the completion of the project--and even afterward--the entire team responded quickly to every question and concern I had. Their estimate was detailed, fair, and transparent, and they delivered exactly what they promised with no surprises. This is actually the second time I've hired Roof Masters. They fixed my roof about 10 years ago, and because I had such a positive experience, I called them again. It's rare to find a company that provides consistently excellent service over the years, but Roof Masters has done just that. I highly recommend Roof Masters. Keep up the outstanding work, Chris, Bri, and the entire team!

We researched local SD County roofers (from where we're at now - over 1500 miles away) and discovered Roof Masters. Chris L., our Project Manager inspected the roof and provided a VERY thorough analysis, complete with pictures and video. He then developed an estimate with several options. We opted for the 40 year workmanship warranty, and learned that the GAF shingles manufacture's warranty is good for 50 years. Roof Masters communication's and presentation was impressive and detailed. We were informed of what materials and methods would be involved in the process of reroofing our house, and kept advised of changes and milestones before, during and after the 4 day job. Brianna our case administrator made the electronic document, invoice and payment transactions simple, fast and efficient. Looking at the galleries of before and after photos, we are pleased and thankful for the complete roof work accomplished by Chris L. and his Foreman Mr. Santos. Our son was in the area and confirmed it was well executed.
