Not a forecast. 52 solar systems around Carlisle were metered through 2024, and the middle half made 703 to 833 kWh for every kWp of panels.
A good roof does better still: the top tenth here reached around 885 kWh per kWp, against a British median of 766.
That places Carlisle 25th of 49, ahead of 24 of the areas we can measure.
At the other end, the quietest tenth of systems here made about 612 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 Carlisle 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.
