Solar Heritage

Our roots date back to 2001 with the founding of Akeena Solar, a Silicon Valley company that grew to be the largest home solar installation company in the last decade with over 10,000 customers in California, New Jersey, New York, Pennsylvania, Connecticut, Colorado and Hawaii.

Akeena partnered with the Westinghouse Electric Company to create Westinghouse Solar in 2010, and then merged with a global energy company in 2012.

Cinnamon Energy Systems was founded in 2012 to continue the vision at Akeena Solar: developing and installing home solar power systems optimized to produce the most electricity for the lowest price.

The Right Solution

Like many large purchases, there are a variety of choices available in the market and a “one size fits all” strategy and manufacturer definitely does not fit everyone’s energy, budget and aesthetic needs.

We take your objectives, current and future needs, and budget into consideration to custom-build a solution that is right for you.

You can start with a modest solar power system today  and add battery storage over time, or build out your dream solar and battery storage system all at once. We will help you get there.
