PVGIS is a really useful tool for modelling generation https://re.jrc.ec.europa.eu/pvg_tools/en/

Thanks, that is helpful.

The estimated yearly PV energy production value on PVGIS is 1,344 kWh.  The PV Watts US site gives me 2,163 kWh, so quite a difference.
*edit - Energy Saving Trust is 2,113 kWh (but less input params in their calculator)

The quote i have assumes 1,954 kWh. Still high maybe.

Consumption is currently 1,600, but I can't see it ever going much lower than that.

Maybe solar isn't feasible at current installation prices in this house.
