I picked up 5 - 4' x 12' & 2 - 4' x 8' Fafco Sunsaver Solar Panels with 2" Headers from Craigslist that I will be self installing. I'm doing research online and read typically you do opposite end feed and returns. I have read that a benefit of the Sunsaver with 2" headers are same side feed and return up to a certain amount panels.
Is this true? Should I install with same side feed and return? That would be much easier and less pipe to mount to the roof.
