I recommend this course to everyone that's looking for a deeper understanding of solar pv design and the relationship between, cold temperatures and open circuit voltages and solar panels connected in series..

Taking this course is an eye opener on the many misconceptions out there in the solar industry

String Sizing can be a slight nightmare of math for students. Sean used this course to chase away the Terror Monster.

I really liked the course because it’s well structured and practical. Even though English is not my native language, I was still able to follow it — sometimes my brain had to translate first 😄 — but at the end of the day, numbers don’t speak English or Spanish, so the formulas and calculations were easy to understand and apply.
