Number of panels is a great point, ours are triple, Maxlight too, like @Tenderloin but ours are just a little bit bigger and considerably more expensive.
It sounds counter intuitive but a smaller opening 3-4m may be better off with more panels so you can open them up more.
For instance, 3x1m = 2m opening vs 2x1.5m = 1.5m opening.
