Fremont, Calif.-based PetersenDean Roofing & Solar, the largest privately held solar and roofing company in the U.S., has announced its acquisition of Haleakala Solar, Hawaii’s largest solar and battery installer. According to PetersenDean, the acquisition is poised to grow Haleakala’s sales to about $100 million in the next two years.
Haleakala has been installing PV solar and water heating systems along with battery storage solutions for over 40 years, employing about 125 people. PetersenDean’s strategic acquisition aims to expand into the remaining Hawaiian islands and add 1,000 jobs.

“PetersenDean is a perfect fit for Hawaii given our size and product offerings, in addition, we have the finance options to truly help the island community to install a new roof, solar or a home battery at very low monthly payments,” said Jim Petersen, president and CEO of PetersenDean. “We look forward to growing our business in Hawaii and adding more American jobs in doing so.”
Hawaii’s 2015 mandate that all islands operate on 100 percent renewable energy by 2045 was the first clean energy standard of its kind in the U.S. For this reason, “the islands are a virtual incubator for all new technology in this space,” says Gary Liardon, president of PetersenDean’s consumer division.
PetersenDean says the company is on pace to grow its revenue from $400 million to over $1 billion over the next few years.
