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.

This is the essential precursor for making AZO transparent conductive film and a good example of a double displacement reaction – where two soluable salts are mixed and an insoluable product results. Pretty much all acetates are soluable and decompose on heating to give the corresponding metal oxide. It’s a good way of forming thin films and of doping the oxide prior to decomposition.
