Specifically:

> Power companies argue that a solar house doesn’t pick up enough of the cost of all it takes to make energy available around the clock. If those solar homes don’t pay for upkeep, they contend, other customers eventually get stuck with higher bills.

Honestly, a solar house seems like it really is only beneficial to itself; it only has the capacity to produce power for itself, and maybe a fraction above. Nothing worth selling back "wholesale".
