solar maintenance near meMaintenance and troubleshooting of commercial and residential solar PV systems are rapidly becoming one of the fastest growing segments of the solar PV industry, and more professionals with troubleshooting skills are needed.

This course covers aspects of start-up procedures, testing, troubleshooting, and maintenance requirements for residential, commercial and battery-based PV systems.

Course Outline:

  1. Module Failure Modes
    • PV module degradation scenarios
    • Potential induced Degradation (PID)
    • Testing modules to create an IV curve
    • Locating hidden problems
  2. Conductor and grounding problems
    • PV source and output circuit conductor failures
      • pinched and chafed conductors
      • poor or faulty connections
      • insufficient conductor rating
    • PV array DC grounding failures
      • grounding conductor is insufficiently sized
      • poor connections of bonding equipment
      • insufficient grounding electrode system
      • faults to ground from PV conductor
  3. Inverters, Monitoring, and Performance
    • PV system failures
      • inverter failure and fatigue
    • Monitoring PV system operation
    • Predicting PV system performance
    • Energy storage systems
  4. Energy storage system types
    • Causes of component or system failure
    • Troubleshooting the system
    • Conduit for the application
