At 22.2%, a square metre of this panel produces meaningfully more than the 15.7% flexible panels — roughly 40% more from the same area.

Two in series is nearly 88V at standard conditions and more on a freezing bright morning — close enough to a 95V controller's ceiling that you should check the cold-temperature calculation rather than assume.
