Annual Savings
Phoenix receives more sunshine than virtually any other major US city, with an average of 6.58 peak sun hours per day. This makes the Valley of the Sun an exceptional location for solar energy, despite Arizona Public Service's shift away from traditional net metering.
APS now uses a Resource Comparison Proxy (RCP) rate to credit solar customers for excess generation, which pays less than full retail but still provides meaningful savings. The Arizona 25% state tax credit (up to $1,000) and 100% property tax exemption add to the financial case.
With installation costs among the lowest in the nation at around $11,400 for a 6kW system after federal credits, and annual savings of approximately $1,450, Phoenix homeowners can expect a payback period of about 8 years - with 25+ years of free electricity after that.
