Utilities will require a(n) ___.

Utilities will require a(n) ___.

• A. Statement of work
• B. Wiring diagram of the PV system
• C. Engineering study
• D. Interconnection agreement

Answer: (D)

Utilities will require an interconnection agreement. This document sets the terms for tying a PV system into the electrical grid, covering safety requirements, protection and back‐feed controls, metering and billing arrangements, inspection and commissioning, and the responsibilities of both the utility and the system owner. It provides the formal approval and ongoing framework the utility needs to ensure safe, reliable operation and proper coordination with the grid. The wiring diagram is essential for installation but is a design tool, not the formal interconnection contract; a statement of work describes project scope between the contractor and client; an engineering study may be needed for larger or more complex interconnections but isn’t required for all systems.
