What matters is longevity and price per watt, first and foremost.

High-efficiency solar panels might be cool for spacecraft or other highly limited space installations, but generally it really isn't the absolute first priority.

I'm the big picture, maybe. On the other hand, there are plenty of cases where efficiency-per-size may be more important than price-per-efficiency given the available surface area to place a panel.
