Not a forecast. 123 solar systems around Warrington were metered through 2024, and the middle half made 709 to 816 kWh for every kWp of panels.
A good roof does better still: the top tenth here reached around 839 kWh per kWp, against a British median of 766.
Systems here land unusually close together — just 107 kWh per kWp between the lower and upper quarter, against 161 nationally. Results in Warrington are more predictable than most of Britain.
That places Warrington 30th of 49, ahead of 19 of the areas we can measure.
Systems here are smaller than typical, a median of 2.5 kWp against 2.9 nationally.
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 Warrington 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.
