That is impressive, but IMO, it needs to be done by the utilities, not
by each homeowner. Barring some technological breakthrough, they have
an economy of scale that we individuals can not match at present.

To be more specific, I am puzzled why, after all these years, solar
cells are still so expensive. By now they should be as cheap as the
sand they are made from.
