Thanks, that certainly helps on the inverter, split and sizing.
I think the numbers on 4 vs 8 probably show what I assumed, that the payback period will broadly speaking be the same on both, and the real financial benefit only starts to make a difference after this, so c year 7ish onwards. So if I was definitely staying put after this I would do, but I will get some quotes on the larger system just to double check return.

Thanks all

100% recommend a split array, you said someone is usually in during the day...itll give you more USABLE energy throughout the day, that extra free electricity in the AM and PM is worth a lot more to you I imagine than the extra couple of kwhs at 14.38p a pop...

I would probably ditch the company who pushed for a single array. And no, you cannot run a split array on a single tracking inverter.

Within a MONTH?! Ha, any installer worth their salt will have it sorted in 2 weeks max.

Actually WPD give a 6 week timescale for approvals, if you've sorted yours within a fortnight then good for you, I've only gone on experience for my own install and for that of my parents
