Search results promise solar panels that plug into a wall outlet. The technology is real, but the marketing skips the safety and legal nuance. Here's the full picture.
What 'plug into outlet' really means
It means a microinverter is doing the work. The panel produces DC, the microinverter outputs grid-synchronized AC, and the cord plugs into a standard receptacle.
Why a bare panel is dangerous
A panel alone outputs DC at potentially lethal voltages and has no anti-islanding or sync logic. Plugging it into AC wiring is unsafe and not legal.
Safe kit features
Look for UL-listed microinverter, anti-islanding, GFCI compatibility, outdoor-rated cabling, and documentation aimed at U.S. installation.
Outlet and breaker rules
NEC limits backfed current on a branch circuit. Bigger kits should use a dedicated circuit, often via an electrician.
Buying checklist
U.S. certification, clear interconnection guidance, supplier with U.S. support, and your utility's written OK.
