My 2 solar collectors are also vertically mounted.
That angle is actually for PVC panels which are aimed for year round best angle. As our solar collectors are generally used from Oct. to May, they are aimed at a lower sun. As a matter of fact Mar, and Oct. are the best times for my collectors.
As the sun climbs in April and May the temps actually go down as the higher angle reflects more radiation.
I start to cover them around late April so they don't warp form overheating.
Now if we could collect that summer heat.............
