Space WAS a factor for us so we manufactured a 40' post mount system that went up to just above rail height (52" pool) then ran at 45 degrees up another 60" - the posts are pvc (concreted in) with chickenwire overlay base for the panels to lay on - pvc runs across the top to connect them and there are 3 top to ground support posts off the back. This fits 4-2x20' panels or 2-4x20' panels. We currently have 3 2x20' panels plumbed into a diverter, will add a 4th or alternate panels if we need to, but it keeps our pool at 84-88 so far so don't have a need for more. It looks a bit like a pergolla. I have hooks to hang the pool cleaning tools and towel racks mounted to it.
