Yep, heating will be extremely minimal (currently modelling at 12 kWh per m2), but we'll have underfloor heating downstairs (good for even solar gain distribution) and a combi boiler as gas will suit us for the next 20 years. ASHP would've be ideal, but we felt there was no need to overcomplicate things given access to gas... the panels are primarily to bring our primary energy demand down (in line with the PH principle).
(If it was just me I'd have put PV on the whole of the south facing roof too...)

Good stuff. So in the interests of keeping it simple PV > ST

Fair enough. I think a proper integrated PV roof looks infinitely better than a stick-on array, but each to their own. Well done for going PH. What will your heating be (backup that is, I know with PH it is minimised). Solar water makes sense if you've got no easy alternative for hot water (I.e. if you were off gas grid).
