Metered, not modelled
Solar output in Liverpool

the middle half of 144 real Liverpool systems, measured over 2024

A typical 4 kWp system here made roughly 3,000 to 3,360 units of electricity last year.
Not a forecast. 144 solar systems around Liverpool were metered through 2024, and the middle half made 750 to 841 kWh for every kWp of panels.
A good roof does better still: the top tenth here reached around 867 kWh per kWp, against a British median of 766.
Systems here land unusually close together — just 91 kWh per kWp between the lower and upper quarter, against 161 nationally. Results in Liverpool are more predictable than most of Britain.
The local roof stock is unusually well pointed: 97% 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 Liverpool 13th of 49, ahead of 36 of the areas we can measure.
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 Liverpool 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.
