Metered, not modelled
Solar output in Edinburgh
681–824 kWh per kWp a year
the middle half of 726 real Edinburgh systems, measured over 2024
- Systems measured 726
- Median 765
- Best 10% of roofs 863
- Rank of 49 areas 33rd
- Typical system size 2.9 kWp
A typical 4 kWp system here made roughly 2,720 to 3,300 units of electricity last year.
Edinburgh has one of the largest metered samples in Britain. 726 solar systems here were read from their own meters through 2024, and the middle half made 681 to 824 kWh for every kWp of panels.
A good roof does better still: the top tenth here reached around 863 kWh per kWp, against a British median of 766.
That places Edinburgh 33rd of 49, ahead of 16 of the areas we can measure.
At the other end, the quietest tenth of systems here made about 585 kWh per kWp — usually shade, a poor direction, or both.
The local roof stock is unusually well pointed: 92% 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 Edinburgh 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.
