Solar potential in Sweden
These figures are the unweighted mean of the city locations listed below, not a national average. Two urban points do not represent an entire country, its roofs or its solar installations.

PV output is estimated electricity from 1 kWp of installed solar panels. Irradiation is sunlight energy received per square meter on the optimally tilted panel plane; it is not electricity.
For a 5 kWp system, multiply the electricity values by five. This simple scaling does not account for roof-specific shading or equipment constraints.
Range across these cities: 957–991kWh/kWp/year. Panel tilt and direction are location-specific; see each city.
Monthly solar irradiation and PV output
Highest-output month: May · 134.9kWh/kWp/month. Lowest-output month: December · 14.6kWh/kWp/month.
The chart and table use the mean of the listed cities for each month.
| Month | Estimated PV output (kWh/kWp/month) | Solar irradiation (kWh/m²/month) |
|---|---|---|
| January | 21.5 | 25.3 |
| February | 42.8 | 49.2 |
| March | 92.6 | 109.2 |
| April | 123.5 | 150.5 |
| May | 134.9 | 169 |
| June | 134.7 | 172.1 |
| July | 129.4 | 166.9 |
| August | 111.2 | 141.4 |
| September | 87.6 | 108.7 |
| October | 56.6 | 67.8 |
| November | 24.9 | 29.5 |

Data and methodology
PVGIS 5.3 (European Commission Joint Research Centre), crystalline silicon, fixed free-standing installation, 1 kWp, 14% system losses, equator-facing panels with optimized tilt and the terrain horizon. Long-term climate estimates are not a forecast or a roof survey. Nearby buildings, trees, roof constraints, snow and local conditions can change actual output.
