Another company serving the solar industry has moved into Arizona.
The Phoenix Business Journal reports the California-based company, REC Solar, specializes in installing solar systems on homes and businesses.
Since it was founded in 1997, REC has installed about 2,500 solar systems.
The move is driven by the state's strong market for solar distributed power, said Angiolo Laviziano, REC's president and CEO.
"I see the changes at the county and Phoenix level, particularly with the green city initiative," he said, referring to Phoenix's plan to turn the Phoenix area into a carbon-neutral region, where much of the power is supplied by solar.
REC Solar offers solar systems for sale or lease to residential, business and government entities such as school districts.
Arizona is the sixth state REC has entered.
It started in California and has spread to Hawaii, Oregon, New Jersey and Colorado.
