PREVIEW THE COURSE MATERIAL

Complete the 40 Hours of Material As Fast As You Want
Some students take the whole 40 hours in one week. That is an intensive amount of work, and most students have full time jobs which is why we split the modules out over 6 sections, intended to be taken one per week but its entirely up to you. You can print your certificate of completion as soon as you finish.

NABCEP Advanced Credits Toward the NABCEP PV Installation Professional Certification Exam
You need 58 hours of advanced training to sit for the NABCEP PV Installation Professional certification exam. If you passed the NABCEP PV Associate Exam after completing our Solar PV Boot Camp + NABCEP PV Associate Exam Prep course, that got you the first 18 hours. This course covers the additional 40 hours you need.
