US: is plug-in solar legal?

Small, plug-and-play “balcony solar” kits are a different product from roof-mounted systems — and their legal status varies sharply by country. Compiled August 2026.

Patchwork — state by state

Legal in a growing number of states, not others — check yours

As of August 2026, 8 states have signed plug-in solar bills into law (Utah, Maine, Virginia, Colorado, Maryland, Connecticut, Vermont, New Hampshire), with roughly 23 more states having live legislation. New York’s SUNNY Act passed the Senate and Assembly in May 2026; California’s SB 868 passed the legislature and is awaiting the Governor’s signature. The typical approach is reclassifying small systems (under ~1.2kW) as a household appliance rather than a power plant. This is changing fast — status depends entirely on your state.
