The term commissioning of a solar panel system is the process of running all the proper system checks and tests to ensure that the solar panels and inverters are all working properly. Some companies may do this on a different day with a technician.

After the installation is complete, the solar panel system undergoes a commissioning phase, which usually takes one to two weeks. This process involves testing and fine-tuning the system to ensure that it operates efficiently and safely.

Commissioning is a collaborative, quality-driven, systematic process that focuses on verifying and documenting that a building and all of its systems are planned, installed, inspected, tested, operated and managed as designed.
