Metered, not modelled
Solar output in Birmingham
701–814 kWh per kWp a year
the middle half of 150 real Birmingham systems, measured over 2024
- Systems measured 150

A typical 4 kWp system here made roughly 2,800 to 3,260 units of electricity last year.
Not a forecast. 150 solar systems around Birmingham were metered through 2024, and the middle half made 701 to 814 kWh for every kWp of panels.
A good roof does better still: the top tenth here reached around 842 kWh per kWp, against a British median of 766.
The local roof stock is unusually well pointed: 98% of these systems face south, south-east or south-west, against 86% nationally. Some of the figure above is orientation rather than weather.
That places Birmingham 31st of 49, ahead of 18 of the areas we can measure.
Systems here land unusually close together — just 113 kWh per kWp between the lower and upper quarter, against 161 nationally. Results in Birmingham 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 Birmingham 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.
Birmingham: the middle half of 150 systems made 701–814 kWh per kWp.
