Borrego Solar is the largest privately owned commercial solar installer with operations in California, Massachusetts and New York.

“Borrego’s electricians in California are wonderful to work with. For emergency work, I get pictures and detailed write-ups the next day. They follow-up on warranty replacement parts without me having to remind them. And they make recommendations to keep our systems up and running as profitably as possible. They always seem to be able to do what I need them to do, when I need them to do it.”

A Brief Company History

Borrego Solar was established in 1980 by Dr. James Rickard, a San Diego State University Professor of astrophysics who lived in the town around the Anza-Borrego Desert State Park just east of San Diego, California. This is where the name “Borrego Solar” comes from.

In 2001, Borrego Solar’s focus shifted towards grid-tied solar installations for homeowners and small businesses. The company moved to the San Diego metropolitan area where it steadily grew its customer base in Southern California and eventually expanded to Berkeley in Northern California.

As the two California offices of Borrego Solar raced to keep up with the demand for residential clean energy solutions, other states with notoriously high energy costs—like Massachusetts—seemed to take notice.

In 2007, the New England branch of Borrego Solar opened just outside of Boston, Massachusetts, and the mission to accelerate the adoption of solar energy continued on the east coast.

A few years later, the organization’s strategic direction changed with the decision to focus 100% of its resources on the commercial and utility markets. By focusing on larger scale projects, Borrego Solar was able to make a greater impact on the environment and the communities it serves by moving from installing kilowatts to Megawatts.

As awareness in solar technology increased, and more state governments found creative ways to incentivize installations through renewable energy credits and innovative PV programs—the solar industry as a whole grew exponentially. This was the impetus behind Borrego Solar’s expansion into new markets, and in 2013 operations in New York were officially launched.

In 2015, on the 35th anniversary of the company’s founding, Borrego Solar expanded its solar operations and maintenance (O&M) offering to non-EPC customers in need of an experienced partner to monitor, maintain and operate existing photovoltaic assets in operation.

A year later (2016) Borrego Solar formally launched its Energy Storage Division to meet the increasing demand for greater control over peak load shifting and intermittency issues faced by municipal and investor owned utilities.
