Arizona Public Service triggered a major debate in 2014 when it first proposed owning and operating rooftop solar systems.
The large investor-owned utility initially sought to develop 20 megawatts of solar PV on 3,000 rooftops, all on the utility side of the meter. Arizona Public Service (APS) said the program would give more customers a chance to go solar and allow the utility to study the potential operational advantages of installing rooftop solar with advanced inverters.
National solar companies and solar advocates engaged in bitter policy battles with APS viewed the program differently, though.
