APS - Solar Water Heating Incentive Program

July 08, 2019


Through the Renewable Incentive Program, Arizona Public Service (APS) offers customers who install solar water heating 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). While there are no longer any up-front incentives or production-based incentives available for grid-tied PV systems, APS offers a streamlined process to interconnect renewable distributed generation. Please see www.aps.com/dg for applications and resources.
