A south roof with 20 panels, 20,000 kWh a year, someone home in the daytime. Price after the green tech deduction, Numsolar's example prices. More cities are coming.
How the cities differ
The sun gives 950 kWh per kW of panels a year facing south in Stockholm. The power price differs more across the country than the sun: the spot price averaged 0.45 kr in SE1, 0.46 kr in SE2, 0.79 kr in SE3 and 1.04 kr in SE4 over the last year. So the same kWh of solar you use yourself is worth more in southern Sweden than in the north. The grid fee and the energy tax differ too, and we use each city's own.
How we calculate
- The same calculation as our calculator: the sun every 15 minutes, power, battery and car hour by hour.
- Weather from PVGIS for each city, the spot price of the city's price zone over the last year and the city's grid company.
- Numsolar's example prices for installers, after the green tech deduction for one owner. Your installer's price will differ.
Questions and answers
Do solar panels pay off in Sweden?
On a roof facing south, south-east or south-west: yes. In Stockholm, 20 panels cost 131,945 kr after the green tech deduction, save 9,438 kr a year and pay back in 14.0 years, with our example prices. East and west take longer; north rarely pays off.
Where in Sweden do solar panels pay off best?
Where the power price is highest. The spot price was 1.04 kr in SE4 (southern Sweden) and 0.45 kr in SE1 (northern Sweden) over the last year. The sun differs less between cities than the price does. The roof still matters most: a south roof gives far more than a north one, wherever you live.
