Not sure how much more power the SE would generate, but even if it's 500Kw per year, at 40p (off peak rate) that's £200 a year, so 7.5 year pay back.

40p/kWh seems a rather high value to put on your own generation - especially if that's your off-peak rate.
10-20p/kWh would be more normal.

Basing it on the fact that I'd have to import additional peak time units at 40p. Appreciate it's not that simple, as I may export that additional power and so sell at 15p and buy back at 40p - but 40p represents the best case

Not sure if it helps but SE optimisers maintain the voltage of all panels at a high voltage. They can also be connected in a long single string. Presumably this means the DC voltage will be higher than a string inverter system, which may help the DC transmission losses.
