The 51-State Question of Plug-In Solar
A state-by-state guide to US rules, certifications, products, and apartment questions surrounding solar systems that plug into a standard wall outlet.
Field notes
The guide treats plug-in solar as a jurisdiction-by-jurisdiction research problem rather than a single national question. Its status system separates enacted laws, bills awaiting governors, measures that passed one chamber, committee bills, failed sessions, missing statutes, and unchecked jurisdictions; the homepage reports 19 not yet checked. Separate references explain why 1,200 watts recurs in legislation and how UL 3700 appears alongside other certification requirements.
