Plug-in solar — a panel or two that mounts to a railing or wall and feeds power straight into a standard outlet — is one of the fastest-moving corners of state energy policy right now. We covered the core legal picture in our balcony solar legal guide, but readers kept asking for one thing: a single reference table covering all 50 states, not just the ones that have already passed a law. This is that table.

The 9 States With Signed Plug-In Solar Laws

As of September 27, 2026, nine states have signed dedicated plug-in solar laws, but only four are in effect today. Signed isn’t the same as in effect, so check the date column before you buy.

Waiting on a Governor

New York: the SUNNY Act (S8512C/A9111C) passed both houses on May 28, 2026. It follows the common 1,200W framework and is not law yet.

California: SB 868, the Plug and Play Solar Act (author’s page), passed the legislature in late August 2026. The governor’s deadline to sign or veto is September 30, 2026. If signed, it’s reported to take effect January 1, 2027 with a 1,200W cap. We’ll update this line after the deadline.

Full 50-State Reference Table

Here’s every state (plus Washington D.C.), sorted alphabetically, with its current status. “Gray area” means plug-in solar isn’t explicitly banned, but there’s no formal exemption law yet — you’d be relying on your utility’s general interconnection rules, which vary widely and were not written with plug-in kits in mind. A meaningful number of gray-area states below have active bills sitting in committee; we’ve flagged the ones we could confirm, but committee activity moves fast, so treat that flag as a starting point for your own check, not a guarantee.

What “Gray Area” Actually Means

Being in a gray-area state doesn’t mean plug-in solar is illegal — it means there’s no dedicated state law that exempts small plug-in systems from standard interconnection rules. In practice, that leaves you dependent on your specific utility’s policies, which were almost never written with a 400–1,200W plug-in kit in mind. Some utilities will look the other way on a single small panel; others technically require a full interconnection application meant for rooftop systems many times larger. There’s no way to generalize this at the state level, which is exactly why the states above have been passing dedicated exemption laws in the first place — to remove that ambiguity.
