Take a deep dive into National Electrical Code (NEC® 2017) standards as well as other best practices that pertain to designing grid­-direct PV systems. The focus in PV202 is on residential and commercial­-scale systems, but the Code requirements, design parameters, and best practices are applicable to all types and sizes of PV installations. Detailed lessons address requirements for disconnects, overcurrent protection, and wire sizing; interconnection requirements and calculations; grounding, ground-­faults, and surge protection; calculations for system sizing, inverter selection, and electrical configuration; ground and roof mount details; and commissioning and performance analysis procedures.

What you will learn:

Commercial system equipment specifications including inverters, racking, and three-phase interconnection are covered; as well as site considerations for roof- and ground-mounted arrays, including layout and inter-row shading. PV202 thoroughly addresses array sizing with various inverter configurations, in order to assess design options and optimize performance. Students will learn to evaluate system performance under various operating conditions, and identify and correct installation errors including ground-faults. This course combines class lectures with individual problem solving exercises covering common design considerations.

Students who complete the workshop will be able to perform the following:

  • Determine requirements for disconnects and series fusing, including labeling
  • Perform interconnection and labeling calculations for single- and three-phase AC services
  • Specify inverters based on system variables, and size inverter subpanel combiners
  • Perform calculations related to mounting PV arrays, including inter-row shading and uplift forces
  • Examine array mounting options for large systems
  • Size grounding conductors for the AC and DC side of the system, and identify causes of, and troubleshooting procedures for ground-faults
  • Optimize the match between an inverter and array, and perform sizing and interconnection calculations for commercial-scale systems
  • Identify installation considerations to meet NEC requirements and ensure long-lasting, safe systems
  • Locate and troubleshoot common installation errors when commissioning a system
  • Perform production analysis calculations to compare expected output to measured output for an operating system
