I sure wouldn't mind bigger panels. However, the ones I have were free. Sometime in the future, I'll invest in bigger/better.

Take careful note of common panel sizes and mountings so that you don't construct yourself into a rebuild if those free panels are somehow configured uniquely.

Some of these things can be a little different from one another.

happy coaching!
