Question about solar panels

[NWMNMom]

Where/how are the individual panels connected to each other? And what brand are they? Some are molded/manufactured so that EACH panel will have a "loop" in them that forces the water from the INLET on the bottom of a labeled end (usually bottom right if label is facing up) across the bottom to the left, up and back acrossed the top to the right at an OUTLET on the top right of the labeled end - a connector hose runs from that OUTLET to the next panel's INLET and it repeats its path through each panel that way.

Then if that brand is manufactured/molded in that manner, would the panel not be able to be plumbed without some kind of modification to just run in all across one end and out all across the other end as shown in the diagram above? I know we just kind of went through this in an earlier post, with this attached diagram showing what was suggested there - the idea being that all panels receive the incoming cold water at the same time and all panels send their heated water to a shared outlet at the same time (probably with some better variation than shown here to equalize the pressure across all inlets and outlets). Dimensions for demonstration only, not meant to be exact or anything. Layout could probably be modified to better fit an area, so long as the plumbing path and end result are the same.

Ok guys, IS this what was suggested before for a more efficient use of multiple panels of this type (with internal loop)?
