Metered, not modelled

A typical 4 kWp system here made roughly 2,640 to 3,290 units of electricity last year.
Not a forecast. 81 solar systems around Durham were metered through 2024, and the middle half made 660 to 823 kWh for every kWp of panels.
A good roof does better still: the top tenth here reached around 865 kWh per kWp, against a British median of 766.
That places Durham 28th of 49, ahead of 21 of the areas we can measure.
Systems here are smaller than typical, a median of 2.5 kWp against 2.9 nationally.
At the other end, the quietest tenth of systems here made about 572 kWh per kWp — usually shade, a poor direction, or both.
What none of it tells you is what your own roof would do. These systems point in every direction and some have been up for fifteen years.
The spread behind that number
Every Durham system, grouped by what it made, against Britain as a whole. The two shapes overlap heavily, which is the honest headline: your postcode nudges the result, your roof decides it.
Durham: the middle half of 81 systems made 660–823 kWh per kWp.
