Metered, not modelled
Solar output in Oxford
691–846 kWh per kWp a year
the middle half of 456 real Oxford systems, measured over 2024
- Systems measured 456
- Median 777
- Best 10% of roofs 882
- Rank of 49 areas 24th
- Typical system size 2.4 kWp
A typical 4 kWp system here made roughly 2,760 to 3,380 units of electricity last year.
Not a forecast. 456 solar systems around Oxford were metered through 2024, and the middle half made 691 to 846 kWh for every kWp of panels.
A good roof does better still: the top tenth here reached around 882 kWh per kWp, against a British median of 766.
Systems here are smaller than typical, a median of 2.4 kWp against 2.9 nationally.
That places Oxford 24th of 49, ahead of 25 of the areas we can measure.
At the other end, the quietest tenth of systems here made about 600 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 Oxford 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.
