But more to the point, why would one do it with a grid tied system,
when you're better off exporting electricity then using it when the
sun's gone down.

Because the unFIT tariff means they're *not* better off doing that, they
get paid for generating it, and (unless they have a smart meter) paid
again on the assumption they export half of it, but the greedy sods want
to use it all for their solar powered bog seat warmers or whatever.
