Metered, not modelled
Solar output in Aberdeen
733–858 kWh per kWp a year
the middle half of 357 real Aberdeen systems, measured over 2024

A typical 4 kWp system here made roughly 2,930 to 3,430 units of electricity last year.
Not a forecast. 357 solar systems around Aberdeen were metered through 2024, and the middle half made 733 to 858 kWh for every kWp of panels.
A good roof does better still: the top tenth here reached around 890 kWh per kWp, against a British median of 766.
That places Aberdeen 11th of 49, ahead of 38 of the areas we can measure.
At the other end, the quietest tenth of systems here made about 637 kWh per kWp — usually shade, a poor direction, or both.
Systems here land unusually close together — just 125 kWh per kWp between the lower and upper quarter, against 161 nationally. Results in Aberdeen are more predictable than most of Britain.
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 Aberdeen 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.
