As i mentioned in another thread, I am planning my solar install right now.
The roof I have to build on is about 12'x12', so I was going to go with 4 of the 10' panels. I figure thats the equivalent sq footage of two 2x20 panels. My pool is only an 18' round with about 8000 gallons in it.
In looking around, it looks like the 10' panels are intended to be mounted vertically, which doesnt seem logical to me.
Take a look at this installation guide I got off one of the websites:
Wouldnt the panel to far right get a ton of flow, and the panel to the far left get almost none? I assume the bottom left corner would also be the lowest point in the system, with the upper right corner being the highest.
