Arizona Net Billing: What Your Solar Exports Are Really Worth
Solar salespeople still talk like every kilowatt-hour you export cancels one you buy. In Arizona that hasn't been true for years: under net billing, exports earn a set export rate that's meaningfully below retail — which changes the payback math, the ideal system size, and even which direction your panels should face.

Frequently asked questions
Does Arizona still have net metering?
No. Arizona uses net billing: energy you export earns a set export rate (below retail) that is locked for a period at your interconnection date and steps down for new customers over time.
