So I am considering add solar heat however the roof direction is not exactly in the most ideal spot. I would appreciate suggestions on placement of solar panels. The roof direction facing south east seems like the most optimum spot however the run of 50 plus ft across the back of the house seems too much. I have 2 inch plumbing and 1.5 hp pump. I am also considering at least 4 ( 4 x 12 ) fafco panels.
Thanks for all input
