The Resource Comparison Proxy (RCP)
Instead of a 1:1 retail credit, Arizona utilities now use an export rate known as the Resource Comparison Proxy (RCP) or an "export rider." When your panels produce excess daytime power and send it to the grid, APS and SRP pay you a reduced wholesale rate (typically around $0.07 to $0.09 per kWh). This export rate drops slightly each year for new customers, though once you install your system, your specific export rate is locked in for 10 years.
