So I'm adding a DIY solar setup to my AGP this year:
2x 4x20' Fafco Solar Bear in a parallel bank on a 10ft 4/12 rooftop close to the pool, 1.5" plumbing.
The only remaining design choice I'm hung up on is whether to locate the panel bank inlet on the same side or opposite side of the bank as the return.
I understand perfectly well in theory why opposite side is usually recommended to balance pressure across the array, but I question how much of a difference it really makes. And I'm trying to weigh the benefit against the detriment of having an 8' longer feed line with 2 extra 90's to locate the inlet on the far side of the bank.
What do you guys think?
