* Green tech: 15% for panels, 50% for a battery, of 97% of the price, at most 50,000 kr per person and year. Example prices from Numsolar's price list for installers, 2026-11-09. Your installer's price will differ: ask for several quotes. Savings: south roof, 20,000 kWh a year, someone home in the day.
What fits your house?
Pick roof, roof area, power use and car. We give one advice and three options.
Car: at home in the day it charges with solar, else from 17:00.
Our advice: fill the roof. 30 panels (12.6 kW) pays back in 13.2 years and gives 158,248 kr net over 25 years.

Does the roof direction matter?
Yes, more than anything. South gives 2,927 kWh more a year than north with 20 panels.
South-east and south-west are 5% below south, east and west 17%, north 37%. With both east and west, use both; with only north, try the garage.

* 20 panels without a battery, 20,000 kWh a year, at home in the day. 27° roof.
Does a battery pay off?
Not for your wallet. For backup power and more of your own solar: yes.
- 10 kWh on the reference house (20 panels): saves 3,327 kr more a year, costs 54,820 kr more. Paid back in 16.5 years; the warranty is 10 years.
- The deduction is 50% for a battery, but the panels use most of the 50,000 kr cap per person: one owner gets 27,533 kr (33%) for the battery. Two owners: more.
- The battery earns most by storing cheap night power for expensive hours; that is how our calculator runs it. The flows per season are under Seasons.
- Backup power needs an inverter with a backup function. For the fastest payback: wait with the battery.
What makes the biggest difference to the savings?
Five choices, ranked in kronor.
| Choice | Worth | How |
|---|---|---|
| Right roof face | +2,927 kWh/yr | South instead of north, 20 panels. |
| Fill the roof | +99,361 kr net over 25 years | 30 panels instead of 10. A large part of the price is fixed. |
| Power at midday | +1,429 kr/yr | Someone home 8–17 versus all away. Laundry, dishes and hot water in the daytime. |
| Charge the car in the daytime | +862 kr/yr | The car takes 909 kWh of solar a year. Charging from 17:00 gives 0 kr. |
| Battery | +3,327 kr/yr, −54,820 kr | Last in line. See Does a battery pay off? |
We count 30 km of driving a day. The charger (often 10,000–15,000 kr, 50% green tech) is not included: you need it with or without solar. If everyone is away 8–17, 54% of the solar power is sold at the spot price.
How much do solar panels give in winter?
Winter gives 6% of the year's solar. Spring and autumn bring 53% of the savings.
Summer brings 42% of the solar power and the reference house sells 44% of it at the spot price (0.79 kr on average). In winter the panels cover 7% of the house's power; every kWh you do not buy is worth 1.85 kr.

What is special about Norrköping?
Price zone SE3, 59° north, 2.0 kN/m² of snow.
Norrköping lies at 58.6° N in price zone SE3. The noon sun stands 54.9° high at the June solstice and 8.0° at the December solstice. The day is 18.4 hours long in June and 6.3 hours in December. The ground snow load is 2.0 kN/m². The grid is E.ON's. We could not check E.ON's 2026 price list, so the page uses a typical grid fee.
- Spot price SE3
- 0.79 kr/kWh Average over the last year excl. VAT. SE1: 0.45 kr, SE4: 1.04 kr. A higher spot price makes your own solar worth more.
- Grid: typical grid fee
- 0.28 kr/kWh + 600 kr/month Transfer fee excl. VAT, 20 A fuse. You save the variable fee on every kWh of your own. We could not check the grid company's price list, so the page uses a typical fee.
- Sun height
- 55° / 8° At midday at midsummer and midwinter at 58.6° north. The day is 18.4 hours in June, 6.3 in December.
- Snow load
- 2.0 kN/m² Boverket's EKS. The installer sizes the fixings for it.
Benefits of solar in Norrköping
- The spot price was 0.79 kr/kWh in SE3 on average over the last year, the second highest of Sweden's four price zones (SE1 0.45 kr, SE2 0.46 kr, SE4 1.04 kr). The higher the spot price, the more your own solar power is worth. Source: Nord Pool, 2025-11-09 to 2026-11-09
- 30 panels (12.6 kW) make 11,943 kWh of solar power a year. The same amount of grid power causes about 705 kg CO2e a year; your own solar power avoids it (Nordic power mix, 59 g CO2e/kWh, an average for 2021–2023). Source: IVL Swedish Environmental Research Institute, report B11147, 2026

How solid are the numbers?
The same engine as the calculator, example prices, a house without shade.
- Engine: the same as our calculator. Sun position every 15 minutes; power, battery and car hour by hour, one year.
- House: made up, central Norrköping, 27° roof, no shade, 420 W panels.
- Weather: PVGIS for the place. Power price: SE3 spot 2025-11-09 to 2026-11-09 + markup 0.05 kr + typical grid fee 0.28 kr + energy tax 0.36 kr (Swedish Tax Agency 2026) + 25% VAT = 1.85 kr/kWh.
- Price: Numsolar's example price list for installers, incl. VAT, after the green tech deduction for one owner. No charger. Your installer's price will differ.
- Payback = price ÷ first-year savings. Net over 25 years = 25 years of no-battery savings + 10 years of battery savings − price.
- Not counted: panel ageing (about 0.4%/yr), an inverter swap after 12–15 years, a changed power price. They cut the net by about 15%; the ranking holds.

Questions and answers
Do solar panels pay off in Norrköping?
Yes, facing south, south-east or south-west. East and west: yes, 2.3 years longer payback. North: no. Our pick for 20,000 kWh a year: 30 panels (12.6 kW), 175,927 kr after the deduction, saves 13,367 kr a year, paid back in 13.2 years.
Does a battery pay off?
Not for your wallet. 10 kWh saves 3,327 kr more a year and costs 54,820 kr more; paid back in 16.5 years, the warranty is 10 years. For backup power and more of your own solar: yes.
How much do the panels give in winter?
Little. December to February give 6% of the year's solar and cover 7% of the house's power. Summer gives 42%.
Does a north-facing roof work?
It gives 63% of a south roof; the payback is 18.9 years. With another roof face or a garage, use that.
What does price zone SE3 mean for my solar power?
The SE3 spot price averaged 0.79 kr/kWh over the last year. A kWh you use yourself is worth 1.85 kr with markup, grid fee, energy tax and VAT; a sold kWh earns the spot price. SE1: 0.45 kr, SE4: 1.04 kr.
What are the green tech deduction rules?
15% for panels, 50% for a battery and a charger, counted on 97% of the price (the Tax Agency's standard rate, so 48.5% of a battery's price), at most 50,000 kr per person and year. The 60 öre credit per sold kWh ended on 1 January 2026.
