How does a customer's solar PV system get connected to the electric system? Once you've selected an installer, National Grid's Distributed Generation Interconnection page provides guidance on how your solar project will be interconnected to our grid. . Photovoltaic (PV) systems consist of silicon cells that collect energy from the sun and convert it into direct current (DC) electricity. This electricity is then fed through an inverter to become alternating current (AC), the same form of electricity that is used in homes and businesses. The utility connection for a PV solar system is governed by the National Electrical Code (NEC) Article. . Professional Installation is Critical: Grid-tied solar systems require licensed electricians and multiple permits, with the interconnection process typically taking 2-8 weeks and costing $200-$2,000 in fees alone. A grid-connected system allows you to power your home or small business with renewable energy during. .
