What do solar panels cost in Eskilstuna?

The price of solar panels in Eskilstuna after the deduction: what you pay. More panels cost less per kW.

About 51,470 kr of the price (43,981 kr after the deduction) is the same for 10 and 30 panels: installation, inverter, electrical work. The step from 20 to 30 panels costs 43,982 kr and saves another 3,217 kr a year.

With a 10 kWh battery: 47,331–62,308 kr more to pay, 2,688–3,296 kr more a year.

Show the rows with a battery

* 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 140,848 kr net over 25 years.

Compare with north and south

The same house in Luleå and Malmö: 895 and 1,035 kWh per kW against Eskilstuna’s 924.

The same house in each city: 20 panels facing south, 20,000 kWh a year, someone home in the day, no battery. The battery: 10 kWh, the warranty is 10 years.

Does the roof direction matter?

Yes, more than anything. South gives 2,883 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 3,240 kr more a year, costs 54,820 kr more. Paid back in 16.9 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.

Right roof face +2,883 kWh/yr South instead of north, 20 panels.
Fill the roof +90,611 kr net over 25 years 30 panels instead of 10. A large part of the price is fixed.
Power at midday +1,312 kr/yr Someone home 8–17 versus all away. Laundry, dishes and hot water in the daytime.
Charge the car in the daytime +795 kr/yr The car takes 893 kWh of solar a year. Charging from 17:00 gives -1 kr.
Battery +3,240 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 43% 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 6% of the house's power; every kWh you do not buy is worth 1.79 kr.

What is special about Eskilstuna?

Price zone SE3, Eskilstuna Energi och Miljö Elnät's grid, 59° north, 2.5 kN/m² of snow.

Eskilstuna lies at 59.4° N in price zone SE3. Eskilstuna Energi och Miljö charges 29.4 öre per kWh incl. VAT for transfer. A peak charge applies only from 35 A, so a house with a normal main fuse pays none. The noon sun stands 54.1° high at the June solstice and 7.2° at the December solstice. The ground snow load is 2.5 kN/m², a little more than in Stockholm.

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.

Benefits of solar in Eskilstuna

  • 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 11,648 kWh of solar power a year. The same amount of grid power causes about 687 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 Eskilstuna, 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 + Eskilstuna Energi och Miljö Elnät 0.24 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

Do solar panels pay off in Eskilstuna?

Yes, facing south, south-east or south-west. East and west: yes, 2.5 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 12,671 kr a year, paid back in 13.9 years.

Does a battery pay off?

Not for your wallet. 10 kWh saves 3,240 kr more a year and costs 54,820 kr more; paid back in 16.9 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 43%.

Does a north-facing roof work?

It gives 63% of a south roof; the payback is 20.0 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.
