There's no federal 'yes' or 'no' for plug-in solar. Your state sets the broad rules; your utility sets the practical ones.
Why the state matters less than your utility
Two homes one mile apart can have different answers because they're served by different utilities.
Net metering basics
Net metering credits you for power sent to the grid. Some states require it; others don't. Even where required, plug-in scale may not qualify.
Interconnection paperwork
Most utilities have a small-systems interconnection form. Plug-in kits often fall into a gray zone where the utility still wants notice.
Permitting realities
Cities decide on permits. Some require electrical permits for any backfeed; others don't ask for kits under a certain size.
Where to look up rules
Start with DSIRE, your state energy office, and your utility's interconnection page. Then call them.
