This course is based on module 6 of ECREEE curriculum for solar installers. This module aims to master the completion, testing and commissioning of a PV solar installation. After the completion of this course, the installer will be able to visually inspect the entire installation, identify and resolve any deficiencies in the finish, check electrical installation to ensure that wiring, polarity, grounding and connections are correct, switch on the system and check the overall functionality and performance; compare with the expected results, and finalize the system documentation and transfer it to the end user/operator.
