An interconnection agreement is a legally binding contract between which parties?

• A. the solar PV installation company and the customer
• B. the utility and the customer
• C. the solar PV installation company and the utility
• D. none of these

Answer: (B)

An interconnection agreement is the contract that governs connecting a customer’s solar PV system to the electric grid. It is a legally binding agreement between the utility and the customer, detailing safety requirements, equipment standards, metering, protection and testing, who pays for interconnection facilities and fees, and how outages are handled (including anti-islanding protections). The installation company may handle installation and coordination, but they aren’t the contracting party to the grid connection—the agreement is between the utility and the customer.
