A solar-ready main panel includes a dedicated breaker space or interconnection point that allows a PV inverter output circuit to be connected without requiring a full panel replacement. It must be sized to handle both the utility supply current and the solar backfeed current simultaneously, and must comply with NEC 705 rules for interconnection, including busbar ratings that accommodate the combined load.
