This course is an excellent starting point for anyone who wants to understand string sizing in PV systems. Sean White’s explanations are clear, practical, and easy to follow. I now feel confident calculating the correct number of solar modules in series for different environmental conditions. Highly recommended for students and professionals in renewable energy!
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
