perspicacious: 24 volt battery, 2,000 AH------------£5,000
How many times can this 48 kWh battery be filled and emptied over its lifetime?
If a generous 250 times, cost per kWh is 41.7p................

Yes, but I feel that you have been unduly pessimistic regarding battery life. A reasonable quality deep cycle battery should withstand many thousands of shallow cycles to no more than about 25% discharge.
The lead acid traction batteries used in fork lift trucks and milk floats often last 10 years under conditions arguably worse than in an off grid home.
And of course with sensible use of the system, well over half the energy produced would be consumed in daylight being cycled through the battery.
