A typical 4 kWp system here made roughly 2,970 to 3,340 units of electricity last year.
Not a forecast. 107 solar systems around Sheffield were metered through 2024, and the middle half made 743 to 835 kWh for every kWp of panels.
A good roof does better still: the top tenth here reached around 868 kWh per kWp, against a British median of 766.
Systems here land unusually close together — just 92 kWh per kWp between the lower and upper quarter, against 161 nationally. Results in Sheffield are more predictable than most of Britain.
That places Sheffield 21st of 49, ahead of 28 of the areas we can measure.
At the other end, the quietest tenth of systems here made about 623 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 Sheffield 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.
