Which term designates the verification that a PV array has been installed and operates as designed?

• A. Testing
• B. Commissioning
• C. Monitoring
• D. Inspection

Answer: (B)

Commissioning is the process of confirming that a PV system has been installed correctly and will operate as designed. It goes beyond simply putting parts together; it includes verifying that wiring and connections follow the design, safety interlocks and protective devices function properly, and that the system can start up, communicate with the inverter and grid, and meet expected performance under actual operating conditions. This formal verification leads to official handover and documentation that the system is ready for operation. Testing, inspection, and monitoring are related but serve different purposes. Testing focuses on specific checks, inspection is mainly a visual or physical review of installation quality, and monitoring tracks performance after the system is live. Commissioning ties these elements together into the definitive readiness assessment that the installation works as intended.
