Which term describes the process of verifying that a PV system is installed and operates as designed?

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

Answer: (C)

Commissioning is the process of confirming that a PV system is installed correctly and will operate as designed. It’s a comprehensive check that everything has been put together according to the design, performs the required functions, and meets safety and performance expectations before the system is handed over. This typically includes verifying wiring and connections, inverters and protection devices, module orientations and string configurations, interconnection with the utility, labeling, and safety interlocks, as well as functional and performance tests to ensure the system achieves the intended output and operates safely under expected conditions. In contrast, testing tends to focus on specific components or subsystems, inspection is mainly visual and about code compliance, and monitoring refers to ongoing data collection once the system is in use.
