Yup to all, If the power stations stop working your solar panel still create electricty, but instead of it going back into the national grid and being wasted you would have a system where the soilar panels electricity charges a set of batteries, and its the batteries you use to provide power for your home.
If I remember correctly a simple switch is encorporated into the design to decide where the solar generated power goes, IE into the grid or into your batteries. 
And the only stupid questions are the ones people dont ask
Madgirl,... is this what you were talking about in a recent thread?....
N.R,..... can you talk about this a little more please,... how would the average Joe do this,... it would be too easy to have a switch fitted,... wouldnt it?

A key safety consideration is that the PV system will disconnect when the distribution system is not energised. This is to prevent the hazardous situation of the photovoltaic system feeding the network or local distribution system during a planned or unscheduled loss of mains. Such an event is termed
‘islanding’ and presents a potential danger to those working on the network/distribution system.
What this means in reality is if the national grid fails, the PV system is locked out from pushing power BACK into the national grid. Where does that power go? NOWHERE.
All that money and you get precisely nothing. So sorry, should have read the small print.

Unless you have a proper stand alone pv-battery-inverter system NOT tied into national grid, you're basically stuffed. Big smiles for all you who DIY'd yourself a system.
This is what I understood would happen if the power grid failed, this was what we were told when we had ours fitted,.. the power goes off,.. the solar is cut off,... so that your polar panels dont electricute the man fixing the power cut
