Solar Panel Connection layout

[NWMNMom]

I called this morning and he said they actually don't sell the 4x20 single and that they just use the photo from the mfg because they didn't have a photo of 2 of the 2x20s assembled. So, I guess we can make do if we have to. We have already had to send back a box that was damaged when it arrived.

Our thoughts on install - because of the limited sun (shadeless) area south of the pool area, we thought of mounting them on posts as shown in diagram attached just to the north of the pool (diagram shows distance between but will actually be about 2-3' north of pool in front of pine tree row) So, would this layout be efficient? We used a diverter on the single panel we had before for the 18' round, thought we should keep that in the loop. This setup gives us about 40 or so feet of panel area - the total space available is only 54' from east to west. I believe these all have the internal loop in the panels that force the water from the inlet at the bottom to the end then back to the front of the panel out the top. I know the single one does and it is the same brand as the new set.

Feedback? other suggestions?
