Commissioning of solar energy systems involves visual observations as well as tests and measurements to verify the safe and proper operation of the system. Commissioning is performed immediately after PV installations are completed, prior to being operated and put into service for the first time.
Key steps of a solar energy system commissioning procedure includes:


Solar energy systems should be thoroughly tested at the time of commissioning and periodically over their lifetime to ensure proper performance and safe operation. Baseline measurements at the time of Changes in test results over time are used to track system degradation, and identify problems that require attention or service for safety or performance reasons. There are several types of electrical tests conducted on the systems that are used to verify NEC requirements and system performance.

The common types of testing conducted on PV systems are:
