The purpose of this article is to give you a basic understanding of the concepts and rules for connecting a solar panel system to the utility grid and the household electrical box or meter. 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. So, significantly reducing or even eliminating your utility bills with DIY Solar is a near certainty now. This allows energy produced by your solar panels to be fed into the grid when you're not using it, and for you to draw energy back from the grid when you need it. Interconnection is the last step of installing a solar panel system.
