Well, according to the curve, if should be able to pump the water up 50 feet of so, but that does not account for the losses in the filter, and the other plumbing and in the panels.
My Superflo curve starts out around 65 feet a zero flow and it is I think just adequate to run my solar at good flow on a single story. But I have a lot more plumbing to the house than you do.
You can certainly help by using 2" pipe and fittings for everything you add.
BTW, I PM'd Mark, so hope he will help.
