Credits, Certifications and Certification Pathways

NC electrical contractors receive 24 continuing education credit hours. Professional engineers receive 40 PDH credits.  We also offer credits for CPA’s and lawyers.

Our photovoltaics (REPV) course offers participants the opportunity to take the North American Board of Energy Practitioners (NABCEP) Associate Exams for PV, formally known as the NABCEP Entry Level Exam. This course fulfills the education requirements on the journey to becoming a NABCEP Certified PV Installation Professional or PV Tech Sales.  Our instructors are industry leaders and hold certifications, such as our ISPQ Certified Master instructors and NABCEP certified installation professionals. In some cases, they sit on NABCEP’s technical review committees.
