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.

Last night we had our first incident where we really appreciated having a solar power system with battery back up.

After midnight last night a car lost control on the road in front of our house and plowed  into a  power pole knocking out the power in the area.

Our battery back up went into action and we didn’t loose a minute of electricity.

ust 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.
