How net metering works
When panels produce more than you use, surplus energy flows to the grid. Your utility credits your account — at retail, avoided-cost, or buyback rates depending on policy.
Arizona combines excellent sun (6+ peak sun hours) with mature installer competition in Phoenix and Tucson. APS and SRP have different net billing rules — critical to model savings accurately.
- Daytime surplus → bill credits
- Evening usage → draw from credits
- Annual true-up may settle remaining balance
Arizona net metering policy
Arizona state tax credit was limited — rely primarily on 30% federal ITC. SRP and APS export credits differ significantly.
Arizona offers some of the fastest solar payback in the US due to sun + moderate install costs.
Net metering vs battery storage
If export credits are low in Arizona, batteries store solar for evening use. Add-on cost: $8,550 before ITC.
