Not a forecast. 120 solar systems around Stockport were metered through 2024, and the middle half made 704 to 786 kWh for every kWp of panels.
A good roof does better still: the top tenth here reached around 809 kWh per kWp, against a British median of 766.
Systems here land unusually close together — just 82 kWh per kWp between the lower and upper quarter, against 161 nationally. Results in Stockport are more predictable than most of Britain.
The local roof stock is unusually well pointed: 95% of these systems face south, south-east or south-west, against 86% nationally. Some of the figure above is orientation rather than weather.
That places Stockport 39th of 49, ahead of 10 of the areas we can measure.
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 Stockport 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.
