Plug-In Solar in Arkansas — Status: unclear
Is Plug-In Solar Legal in Arkansas?
No dedicated statewide plug-in solar law is identified in our tracker for Arkansas. That does not automatically permit or prohibit every configuration: grid-connected, zero-export, and electrically isolated off-grid systems can be treated differently. Before installing or connecting equipment, confirm current utility or interconnection rules, local code or permit requirements, property or lease conditions, outlet and electrical suitability, and the equipment listing and manufacturer instructions.
