How plug-in solar legality works
States that have passed plug-in solar laws set a maximum watt cap — typically 600W to 2,400W — and most explicitly waive the permit and utility approval requirements. As long as your system stays within the cap, you can install and operate it yourself with no professional sign-off. Always verify the current law with your state utility commission before purchasing.
