Utility Interconnection Best Practices

Responding to increased demand for rooftop solar, Northwest Solar Communities convened a team to develop interconnection practices that make the process of going solar simple, fast, and cost effective for customers and the utilities that serve them. The following best practices are recommended for inverter-based PV systems with a nameplate capacity of 25kW or less. Some practices are already in place in Oregon or Washington, in which case we offer examples of the practice in action.
