State legislatures are doing the work federal policy used to do. Track state rules like a primary diligence item, not a fallback.

North Carolina, Connecticut, and New Jersey all moved on solar policy within weeks of each other — in different directions. State rules now need the diligence rigor once reserved for federal incentives.

North Carolina's solar industry is appealing a state pause on its projects. Connecticut just extended its home solar incentive through 2035. New Jersey's legislature unanimously passed a plug-in solar bill. And solar manufacturers are explicitly betting on state-level support to fill the gap federal policy is leaving. Four different stories. One conclusion: state policy is now doing the work federal policy used to do.

States are moving in both directions at once

This isn't a uniform story of states stepping up to fill a federal gap. North Carolina's pause shows some states pulling back even as others, like Connecticut and New Jersey, extend or expand support. The practical implication is the same either way: state-level policy now needs to be treated as a primary diligence item for every project, not a secondary check performed after federal eligibility is confirmed.

Manufacturers are already repricing this bet

American solar manufacturers publicly betting on state-level support, rather than waiting for federal policy to stabilize, is itself a signal worth taking seriously. If manufacturers building multi-year capital plans are treating state support as the more durable variable, developers evaluating where to build should be applying the same logic to site selection and market entry.

The states worth watching are shifting in real time, in both directions. A project's viability increasingly depends on which state it's in as much as which federal incentive it qualifies for — and that comparison needs to happen before site selection, not after.
