Metered, not modelled
Solar output in Peterborough
655–823 kWh per kWp a year
the middle half of 1,771 real Peterborough systems, measured over 2024
- Systems measured 1,771

- Typical system size 2.7 kWp
A typical 4 kWp system here made roughly 2,620 to 3,290 units of electricity last year.
Peterborough has one of the largest metered samples in Britain. 1,771 solar systems here were read from their own meters through 2024, and the middle half made 655 to 823 kWh for every kWp of panels.
A good roof does better still: the top tenth here reached around 875 kWh per kWp, against a British median of 766.
That places Peterborough 40th of 49, near the bottom of the areas we can measure — worth knowing rather than glossing over.
At the other end, the quietest tenth of systems here made about 523 kWh per kWp — usually shade, a poor direction, or both.
Only 81% of these systems face south, south-east or south-west, against 86% nationally — so part of what you see here is roof direction, not the sky.
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 Peterborough 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.
