Not a forecast. 84 solar systems around Doncaster were metered through 2024, and the middle half made 759 to 858 kWh for every kWp of panels.
A good roof does better still: the top tenth here reached around 884 kWh per kWp, against a British median of 766.
That puts Doncaster 8th of the 49 postcode areas we can measure.
Systems here land unusually close together — just 99 kWh per kWp between the lower and upper quarter, against 161 nationally. Results in Doncaster 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.
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 Doncaster 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.
