About the Course:

This microcredential trains PV technicians to perform essential electrical tests during photovoltaic (PV) system installation and commissioning. Learners will use VR simulations to practice insulation resistance checks, polarity verification, DC string testing, continuity checks, and AC voltage verification. Emphasis is placed on safety, accuracy, and compliance with NEC and industry standards. Technicians seeking structured career advancement can enroll in our Solar Training Program for certification-focused, job-ready training.

Learning Objectives:

  • Perform insulation resistance testing to verify system safety.
  • Conduct polarity testing to ensure correct wiring orientation.
  • Measure DC string open-circuit voltage (Voc) and confirm design compliance.
  • Test DC string maximum power current (Imp) under operational conditions.
  • Perform DC string short circuit (Isc) testing for current validation.
  • Conduct continuity testing to ensure wiring integrity.
  • Verify wire termination torque to manufacturer and code specifications.
  • Perform AC voltage testing for grid connection readiness.

Course delivered via LMS and requires an Oculus VR headset for hands-on VR simulations.
