About this course

This comprehensive 9-hour course, led by Mayfield Renewables Founder and CEO Ryan Mayfield, covers the sections of the 2023 National Electrical Code (NEC) that are most relevant to solar PV systems.

Students can expect to learn about sections of the codebook that pertain to solar PV, including Articles 90, 100, 110, 690, 691, 705, 450, and 750, covering: 
  • Rapid shutdown
  • Disconnecting means
  • Wiring methods and materials
  • Grounding and bonding
  • Source connections
  • Requirements for large-scale PV systems
  • Source connections to a service
  • Load-side source connections
  • PV and transformer overcurrent protection
  • Microgrids and energy management systems
  • And more!
 
This is an adaptation of Ryan's full-day code course that he teaches at conferences like the NABCEP Continuing Education Conference. 

All course registrants will get access to all course materials — including videos, diagrams, and the course PDF.
Registrants can also receive 9 hours of NABCEP CEUs upon completing all three parts in the series.
