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.

Barry Cinnamon



Barry is a long-time advocate of solar power and is a widely recognized solar power expert.

Barry started his career in solar energy in the late 1970’s at MIT researching new flat plate and concentrating collector designs. 

His pioneering work on reducing costs of rooftop solar power systems led to over 30 issued and applied for patents, including a number of products that transformed the solar industry, including Andalay, the first solar panel with integrated racking, grounding and wiring, and Instant Connect, the first fully “plug and play” AC solar panel.

On any given day Barry will either be on a roof working with his installation crews, doing R&D on new solar products in the lab, or working on improving national residential solar policies like net metering and better homeowner financing programs.

Thad began his career in the energy business while in college, working summer jobs as an oil field roustabout in West Texas and as an assistant geologist in Death Valley, CA. Graduating with a degree in Energy Land Management from the University of Oklahoma, Thad went to work for British Petroleum in San Francisco and Houston, securing exploration rights on private, state and federal offshore lands.

Subsequent steps in the consumer electronics and entertainment industries coincided with a growing interest in renewable energy and concern for the environment.  This resulted in the founding of a specialized marketing practice promoting renewable energy and social impact causes, two of which developed into ongoing consultancies: one for a Canadian clean tech startup in the commercial demand response field, and another with a leading solar loan company in Oakland.

Thad joined Cinnamon with the desire to support and grow solar energy with a premier company, long on the front lines of the energy transition.
