Thinking just about max nominal watts of solar panels flat mounted, I imagine picking the highest efficiency is going to push you into mono or hybrid. There are some really high efficiency panels out there now but getting ahold of them in low quantity is nearly impossible.
In particular though I am pretty sure max watts flat on the roof does not always equal max efficiency panels. They make a great benchmark though, and sometimes they end up being the most watts produced to fit a certain dimension space.
All the other items like maintainability, shadow, actually getting the watts OUT of a mix of panels...etc. are all important, but dont really affect the proposed method for maxing out a space on watts.
I'm sure there is a better way - I just have not come up with it.
