What a solar system actually generates in Cardiff
A typical 4kWp roof array in Cardiff, at the optimal angle, is modelled to produce about 4,127 kWh a year — roughly 1032 kWh for every kWp installed. That puts Cardiff around the middle of the UK range, which runs from about 853 to 1163 kWh per kWp.
The modelled optimal tilt here is around 40°. Most UK pitched roofs sit between 30° and 45°, so a south-facing roof in Cardiff is usually close to ideal without any special mounting. A shallower or east–west roof still works, it simply generates less, which is one of the things worth having each installer quantify in their quote.
