Very professional from start to finish.  Barry, the owner, took the time to meet us and came our the site to personally inspect it on several occasions. I love the fact that this a personable local company vs an impersonal nationwide chain. Pricing was also fair and actually cheaper than some of the bigger solar places we compared. Highly recommended.

Approximately 8 years ago I purchased a home solar system from Barry Cinnamon. This review is long over due: The system did everything Barry told us it would do, and, we have recently fully recouped the full cost of the system itself through reduced energy bills. Better yet, after 8 years we have yet to have any need for service.
Trust is a big component of any transaction. Mr. Cinnamon has earned our trust. If you are in the market for a solar energy system I recommend you meet with someone with Cinnamon and allow them to design your system.

We are extremely happy with Cinnamon Solar! For starters, the owner, Barry Cinnamon, gives a weekend seminar which is a great way to learn about the industry, the trends, and the considerations for installing solar.
He answered our questions and he visited our home twice to help make design decisions as we planned for our solar installation.
Our house is just old enough that special considerations were needed for hooking up the power to the PG&E grid. And our new metal roof was a recent model that required special attention for support brackets. Cinnamon dealt with each of these issues and others we raised quite effectively.
They handled the permits with the city, and the contract with PG&E for us to deliver unused energy to their grid.
We are very happy with our solar system, and happy to be doing our small part to contribute to more use of renewable energy.

We recently purchased a home and made the installation of solar a priority.  Through our move, we contracted with many service providers, including movers, floor refinishing, electrical, etc., and without a doubt our experience with Cinnamon Energy Systems was the most transparent and painless.  We opted for a sizable panel installation with a storage (battery) subsystem.  They are easy to work with, responsive, and do high quality work with high attention to detail.  The permitting process was as painless as it could possibly be.  Between the intrinsic economics of solar and the availability of such a competent contractor, adding solar is pretty much a no-brainer at this point.  We give our highest recommendation to Cinnamon.

Just like other reviewers, we had done lots of homework before deciding on a Solar Contractor. Cinnamon became the obvious choice for a number of reasons. They were flexible with regard to panel choice.  They shared our high regard for the use of micro-inverters.  Barry Cinnamon’s unparalleled knowledge of solar systems and the industry created a solar system that is both the best, and the best price per watt out of all our proposals.

It gets better.  Because of the size of this company,  everyone we came in contact with were knowledgeable professionals. No high pressure salespeople, slick brochures or ‘freebie’ tote bags.  Just straight forward honest facts by dedicated people interested in helping you get the best solar system for your money.  This includes (in our case) avoiding an expensive and unnecessary electric panel upgrade. By the way, don’t believe the big outfits that offer a ‘free’ panel upgrade. Look at the bottom line.  It’s not free. And for us it wasn’t needed, despite what the ‘big guys’ told us.

Google Barry Cinnamon and you will learn that he is a highly regarded expert within the solar industry.  Cinnamon doesn’t advertise, it’s all word of mouth.  So call them to make an appointment, then make your own decision.
