Plug-in solar systems—which connect to standard household outlets without professional installation—are moving from regulatory gray zone to approved technology as individual states formalize rules around them. This expands solar adoption beyond homeowners with capital for rooftop systems and landlord approval, directly reaching renters and renters-by-choice who represent roughly 35% of U.S. households. The economics are real (hundreds of dollars annually in savings) and the friction is low. Utilities and grid operators will need to account for distributed generation at scale in capacity planning.
