Metered, not modelled
Solar output in Norwich
740–903 kWh per kWp a year
the middle half of 64 real Norwich systems, measured over 2024

A typical 4 kWp system here made roughly 2,960 to 3,610 units of electricity last year.
Not a forecast. 64 solar systems around Norwich were metered through 2024, and the middle half made 740 to 903 kWh for every kWp of panels.
The best tenth reached about 950 kWh per kWp — some 24% clear of the British median of 766, and among the strongest roofs we can measure anywhere.
That puts Norwich 10th of the 49 postcode areas we can measure.
At the other end, the quietest tenth of systems here made about 629 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 Norwich 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.
Norwich: the middle half of 64 systems made 740–903 kWh per kWp.
