It depends mate theres new Grid systems available including LOCAL grid, SMART rid etc, You can in many cases sell your excess power back to the grid via a feed in tariff agreement, equally you can just have a system that provides power ONLY to your house when the grid fails.
Selling to the grid isnt straight forward, first your local 11KV system must have the capacity, second it must not destabilise the established 11KV system, then you have to ensure your local sub station can take the extra supply and do it without causing " waves or ripples" in the system. A domestic solar array can indeed be set up only to supply your own needs and the excess gets used to recharge your battery bank.
If you get one of these deals where a company puts FREE panels on your roof you get the power to your house for nowt, but any excess gets sent back into the grid and the instalation company gets the feed in tsariff money.
