Metered, not modelled
Falkirk vs Kilmarnock & Ayrshire
Falkirk roofs made about 1% more than Kilmarnock & Ayrshire roofs last year.
681 against 677 kWh per kWp at the median, from 591 and 83 real systems.
Where the two actually overlap
Both areas, grouped by what each system made. The medians differ, but the shapes sit largely on top of one another — a good Kilmarnock & Ayrshire roof beats a poor Falkirk one comfortably. Location moves the odds; it does not decide the outcome.
Falkirk: the middle half of 591 systems made 579–752 kWh per kWp. Kilmarnock & Ayrshire: the middle half of 83 systems made 618–731 kWh per kWp.
Both figures are what real systems metered last year, so the gap mixes sunlight with system age, roof direction and shading. It is the difference in what people actually got, not a difference in sunshine alone.
