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.

This is a great class to learn some calculations relavent to the solar industry.
