How much does latitude matter? Solar yield from Oslo to Seville

Dataset · Updated 21 June 2026 · 24 cities · Arctic to Andalusia

The identical 5 kWp system makes about 1,597 kWh per kWp a year in Seville but only 699 in Tromsø — a 2.29× spread driven almost entirely by where you stand on the map. Latitude is the biggest single lever on solar output, bigger than the panel you choose.

Yield as you travel south (kWh/kWp/year)

Cities ordered north to south. The climb is steady, but maritime cloud (Edinburgh) and clear continental skies bend the line — latitude is a strong trend, not a ruler.

How we worked this out (methodology)

We run the same 5 kWp, due-south, 35°-tilt system through our public engine for a north→south transect of 24 European cities and record the specific yield (kWh per kWp per year) from PVGIS at each city's real coordinates. Yield depends only on location — latitude, cloud cover, and climate — so this study carries no economics, no currency and no FX assumption: the numbers are pure PVGIS output anyone can reproduce. Latitude is the dominant driver, but maritime cloud (e.g. Edinburgh) and clear continental skies also move it, which is why the line is a trend, not a ruler.

Yield is half the story: a sunny country with poor tariffs can still pay back slowly. For the money side, see our payback across European cities study.
