It look awesome by the way!

Whew! Thanks for the info!
Since my last post, I've gotten the underground pipe in (mostly). It was easily a week of digging and probably the hardest part of the whole project so far since it was mostly done with just a shovel. Rocks are not fun!
Basically I dug down 28"-30" made sure everything had a slight slope with a level. I then laid landscape fabric along the bottom of the trench. Over the fabric I laid about 1" layer of washed river rock. Over that base layer of rock I laid a 4" socked perforated corrugated pipe. Then filled the pipe up to its top with more river rock. The extra landscape fabric in the trench folded over the top over the rock & pipe like a big ol' burrito.
Theeeeen, my corrugated underground boiler pipe laid over the drain pipe and I buried by a few inches with some of the nicer soil. I put some strips of 250 psi XPS polyiso over that. I figured it would add some insulation & strength to protect the boiler pipe. The rest of the trench I could backfill with rockier and rougher soil.
At the lowest part of the boiler pipe before it pokes up near the house, I put a bunch of holes in the outside of it in a 1-2 foot section. That style of boiler pipe is basically useless if it fills with water. By keeping the surround soil dry with the drainage below it, then sloping it to a drained low point, it should allow any water that eventually works it's way in to be naturally drained through those holes. Boy I really hope it does, because it was a lot of work to dig it up again! In retrospect, I would've gone with thermopex.
What remains:
1. Hooking up pipes & run sensor wires
2. Run pump & check for leaks
3. Wiring controls
4. Attach glazing
5. The separate pump & controls for the furnace heat exchanger (less important as we're coming out of the heating season).
6. Make things pretty, maybe cut down a few trees if they block the panel too much.
