No plug-in solar legislation had been introduced in Florida as of our last check. That doesn't make every plug-in setup illegal, but there is no law that exempts small systems from your utility's interconnection rules — so connecting one without permission may violate your service agreement.
Off-grid use is a different story: a portable panel charging a battery power station that is not connected to your home wiring needs no permission anywhere.

Florida plug-in solar FAQ
Is plug-in solar legal in Florida?
Not yet. No plug-in solar legislation has been introduced so far. Without a law, connecting a grid-tied plug-in system may violate your utility's interconnection rules. Off-grid setups (a panel charging a portable power station) are allowed everywhere.
How much can balcony solar save in Florida?
At Florida's average residential rate of 15.03¢/kWh (EIA, July 2026) and about 5 peak sun hours a day, a south-facing, tilted 800 W kit saves roughly $151 a year, paying back a $900 kit in about 6.0 years. Vertical railing mounts produce about 30% less.
What is the maximum plug-in solar size in Florida?
There is no Florida-specific cap yet. Most state laws settle on 1,200 W, the practical limit for a standard 15-amp, 120 V circuit.
