Unfortunately, the el sid is way too small for my application. My panels are ~100 feet from the tank. I'm planning on running 1" PEX to my 200 sq/ft of panels. Combine this with the antifreeze which thickens up the water and increases head loss and this gives me a target flow rate of ~10 gpm @ 23.5 feet of head. Only the larger inline taco or grundfos pumps even come close to this.

I also emailed Gary at builditsolar to see if he knew about any new stuff I should look out for. He said there really wasn't anything. So, I'm looking at a Taco 0011 or Grundfos UP26-120U.
