This will all depend on the motor and pump design.  If the motor runs in
phase with the AC (constant RPM), you should see a big drop in power.
If the motor and pump run asynchronys ('just go'), you will get faster
pumping as the head is reduced, but current draw will remain fairly

Use an elevated drainback reservoir that is located only a foot or two
below the panel.  This will reduce max backpressure/head-to-pump to that

That's not what I was suggesting.....

The elevated tank needs only to hold as much as the collectors (and a
few feet of plumbing).

 Wouldn't this be an open tank and I would need a second pump then with the same
height/head problem?
