The PBS TV show "This Old House" has several times shown the innards of
solar-power home installations that sell the excess power back to the
utility. They have a panel of circuitry interfacing the two systems, and
usually two meters, one reading what was bought from the utility, and the
other showing what was sold back. There is a "black box" (actually in
grey electrical cabinetry :-) that does the phase matching between the
two. (The solar systems produce DC, of course, and it is converted to AC
before feeding into this load-balancing and distribution network.)
