  • The sums look more favourable if you're less pessimistic on the figures used.  Octopus Go is still available at 7.5p/kWh, for 4 hours of overnight charging, or about 28kWh.

    On a modern car, 25kWh may only be about half a charge.  So it's not using a full charge cycle every day.  There is no way the battery would need replacing after only 2000 cycles if the charging/discharging is managed properly.  The solar battery in my loft has a 10 year warranty*, and is cycled every day, so that's 3600 cycles.

    *Or would have if the installer had bothered to register it.
