Fremont, Calif.-based PetersenDean Roofing & Solar said it has acquired Hawaii-based Haleakala Solar.

Haleakala Solar was founded in 1977 by Jim Whitcomb and installs photovoltaic solar, water heating and battery storage systems. The new owners plan to add roofing installations.

“Mr. Whitcomb will stay on and take an active role in the sales development segment of the company in Hawaii as we add new verticals to the market and expand to the remaining islands,” said Gary Liardon, president of the consumer division of Petersen, in a news release.

Whitcomb approached Jim Petersen, CEO and president of Petersen, late last year about buying Haleakala Solar, according to the news release.

“The time came to hand over the reins,” Whitcomb said in the release.

Peterson employs 3,000 workers and operates in seven states: Arizona, California, Colorado, Florida, Nevada, Oklahoma and Texas.
