What a solar system actually generates in Portsmouth
A typical 4kWp roof array in Portsmouth, at the optimal angle, is modelled to produce about 4,508 kWh a year — roughly 1127 kWh for every kWp installed. That puts Portsmouth among the stronger locations in the UK, 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 Portsmouth 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.
