The system is completed and running! It has been for a few months now, but life gets in the way. I will take some pics of the hardware, get links for the solar panels, and try to explain that system. It is complicated.
There are loops in the floor of the garage. The solar heat can:
1) heat up about 80 gallons of hot water upstream of the 52 gallon (required) electric tank.
2) Heat the garage floor.
3) Push solar heat into the ground loops.
There is a waste heat recovery loop in the heat pump that heats the water in the 52 gallon domestic tank. This spring the house was in construction mode, heated to about 55 for drying paint and drywall, keeping the moisture out, etc.
The waste heat recovery loop kept the 52 gallons at about 100 degrees F. The electric elements have not been turned on. He will have a huge surplus of hot water when they are in the home full time.
