What the heck is the difference between a 60 cell and 72 cell solar panel? And why should you care?
In this video, I will explain the differences between the two standard configurations of large solar panels. 60 cell panels are sometimes called grid tied panels and 72 cell panels are called off grid panels or battery charging panels. There are size and voltage differences between the two and I’ll explain why.
