In my region (North East USA) 2 x 200W DC solar panels will generate about 440KWh per year. It is generally more economical to reduce demand than to add solar panels. Which is why I'm keen to get the demand down.
My point was that dropping the power demand by 850W was something significant, and I consider that the installers really messed up by wasting 850W down the return well. Fixing that waste has just paid for at least 2 panels when I install the next array.
Doubling the size of the evaporator is very interesting I will discuss with the HVAC people. I will also have to do some research there. Also switching from parallel to series with the evaporator is interesting.
There are no other devices that can cause a pressure drop in the water circuit. The pipes on the inside of the house are all 1" diameter copper, and on the outside 1" PVC (same as sprinkler pipe). In the well they are 1" poly pipe, and the return well goes down to the water line and is sealed. If all the pipes took straightest line rather than making 90 degree turns I doubt that I'd save more than 20' horizontal distance in total for supply and return together. But straight lines for the pipes would have been difficult.
I was a little surprised when they fitted the sprinkler type pipe in the trench (installed with a hydraulic missle/mole). Maybe a different type of pipe or larger diameter here would have been better? That really is too late now, other than to advise others.
