'''''Note: The Arizona Corporation Commission (ACC) recently approved modifications to some elements of this program. Performance-based incentives, which had previously been available for larger renewable energy systems have been terminated. Only upfront incentives for smaller systems are now available.'''''

Through the Renewable Incentive Program, Arizona Public Service (APS) offers customers who install various renewable energy systems the opportunity to sell the renewable energy credits (RECs) associated with the energy generated to APS. APS uses the RECs to demonstrate compliance with the state's[ Renewable Energy Standard (RES)]. The solar technologies eligible for a rebate include photovoltaic (PV), solar hot water, solar HVAC and solar daylighting systems. Up-front incentives for PV may be de-rated based on expected performance. All electricity-producing systems must be connected to the grid.

See web site above for complete details.

Other Information 

Domestic solar water heating systems must be tested and certified to the OG-
300 standard by the SRCC or an APS approved NRTL or ANSI and have a
rating that is accompanied by the certified system design schematic.
Large solar water heating and other solar thermal panels must be OG-100 certified.
