Alexander Niehenke on Michael & Sun Solar, Inc.

These folks are fantastic, fair, and thorough. I got quotes from multiple solar installers, and this one just felt right. Wasn't trying to sell me financing or any other scams. In fact, the payback on the system ended up being on the edge, and the team really pushed me to consider whether I wanted the system. It's rare to find honest people these days.

Michael & Sun was recommended by two of our friends, and after getting 3 quotes we decided to use them as well. From the beginning we were impressed by the professionalism of the M&S team. They listened carefully to our needs both present and future, came up with a proposal which we tweaked several times, and were always available with a quick response (both pre and post-installation) when we had questions or concerns. We were facing a tight year-end deadline, and all timelines were met on schedule. Special shout out to William and Michael who were a pleasure to deal with. Our friends were right, we absolutely recommend going with Michael & Sun Solar!

Michael and Sun performed a thorough job from start to finish. Handled all permitting and inspection in a extremely professional manner. Very conscientious with planning conduit runs and installation technically and aesthetically. I will continue, to recommend Michael and Sun to all my clients planning on going solar.

We were extremely satisfied with Michael & Sun Solar. They were available any time for any of our many questions, even before we signed a contract. We love our solar and battery system. It's been so much fun to harvest the sun. We purchased a second electric car, and it is now the most fun game to catch as much of that free sun that we can.

Can't recommend Michael and Sun enough! They did a fantastic job from start to finish. Very professional, fast, on top of it! They also worked seamlessly with our solar lender and made it very easy for us. Have been, and will continue, to recommend them to everyone I know for solar! Thank you everyone at M&S!
