Solar by stateUpdated September 2026

Solar rules change at the state line.

What a solar system is worth depends on where it sits: how the state credits the power it sends back, what electricity costs there, and which rules an older system keeps. Find your state to see how it works — for buyers, sellers and agents.

Reading the labels: Full retail credits exported power at the retail rate. Reduced pays a set share of retail. Net billing pays an export rate well below retail. Varies means no statewide rule. Older systems often keep earlier terms; each state page says how.
