Should reach grid parity in Italy next year, most of Europe by 2020 and the UK by 2030.

That's assuming trends continue as they currently are.  Which is something that never happens.

The point being that once it costs the same as buying it from the grid people will be happy to install it in their own homes rather than buying it from the grid. Until that point there's no financial incentive to have it supply _any_ of our electricity, purely a social one.
