* 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 13.9 years and gives 140,948 kr net over 25 years.

Does the roof direction matter?
Yes, more than anything. South gives 2,664 kWh more a year than north with 20 panels.
South-east and south-west are 5% below south, east and west 16%, north 35%. 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 3,231 kr more a year, costs 54,820 kr more. Paid back in 17.0 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 | +2,664 kWh/yr | South instead of north, 20 panels. |
| Fill the roof | +91,761 kr net over 25 years | 30 panels instead of 10. A large part of the price is fixed. |
| Power at midday | +1,307 kr/yr | Someone home 8–17 versus all away. Laundry, dishes and hot water in the daytime. |
| Charge the car in the daytime | +794 kr/yr | The car takes 893 kWh of solar a year. Charging from 17:00 gives 0 kr. |
| Battery | +3,231 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, 53% 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 41% of the solar power and the reference house sells 41% of it at the spot price (0.79 kr on average). In winter the panels cover 6% of the house's power; every kWh you do not buy is worth 1.79 kr.

Benefits of solar in Jönköping
- 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

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 Jönköping, 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 + Jönköping Energi Nät 0.23 kr + energy tax 0.36 kr (Swedish Tax Agency 2026) + 25% VAT = 1.79 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

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 12,675 kr a year, paid back in 13.9 years.
Does a battery pay off?
Not for your wallet. 10 kWh saves 3,231 kr more a year and costs 54,820 kr more; paid back in 17.0 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 6% of the house's power. Summer gives 41%.
Does a north-facing roof work?
It gives 65% of a south roof; the payback is 19.5 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 1.79 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.
