I graduated HS in 1989, I've been involved in the Electrical industry since December 1995. I've been on every jobsite except nuclear. "powerhouses" I'm the master Electrician with a Roofing/solar company. February 2024, I entered into "new territory" with Solar, batteries, wind etc. I'm so happy that my employer encouraged me to take my NABCEP - PVIP. I've taken the exam twice and failed (grades 49 then 62. This is because I didn't understand the Calculations. I highly recommend this course because "now" I'm very comfortable, and confident that I'll be able to perform the calculations by "knowing" the steps. Thankyou Sean and HeatSpring
