Denmark Solar & Battery Guide
Quick Verdict
Solar panels: Excellent investment Payback 7.4 years (reference model: 5 kWp, 8,500 kWh demand, no battery).
Batteries: Marginal — calculate carefully.
Key insight: Denmark has very high electricity prices but no feed-in tariff for new systems since 2013. Self-consumption is the only value. District heating is very common — many homes don't need electric heating.
Key Statistics
Electricity Prices (2025–2026)
| Tariff | Price | Notes |
|---|---|---|
| Standard residential | €0.36/kWh | Flat rate — same price 24/7 |
| Feed-in (export) | €0.03/kWh | What the grid pays for excess solar |
| Gas | ~€0.11/m³ | ~10 kWh/m³ |
kWh = kilowatt-hour: The unit on your electricity bill. A 1,000-watt appliance running for one hour uses 1 kWh. An average European home uses about 250–350 kWh per month.
Feed-in tariff warning: The grid pays very little for your excess solar. Self-consumption is where almost all the value is.
Solar Potential
| Region | Solar Output per kWp | 5 kWp System Annual |
|---|---|---|
| Copenhagen | 980 kWh/yr | 4,900 kWh |
| Aarhus (Jutland) | 1000 kWh/yr | 5,000 kWh |
| Odense | 990 kWh/yr | 4,950 kWh |
| Aalborg (N) | 950 kWh/yr | 4,750 kWh |
| Esbjerg (W) | 980 kWh/yr | 4,900 kWh |
kWp (kilowatt-peak): The maximum power a solar system can produce in perfect midday sun. A 5 kWp system = roughly 12–15 panels. Think of it as the "engine size" of your solar setup.
Denmark has moderate solar potential. Typical for Central/Northern Europe.
Electricity Generation Mix
Understanding how Denmark generates its electricity helps explain why solar is (or isn't) incentivised.
| Source | Share |
|---|---|
| Oil | 3.7% |
| Wind | 57.7% |
| Solar PV | 13.4% |
| Biofuels | 20.1% |
Source: Our World in Data (2025). Total generation: 33 TWh.
High renewable penetration: Denmark already gets a significant share from wind and solar. Grid flexibility and storage become more important as variable renewables grow.
Who Uses the Electricity?
| Sector | Share of Consumption |
|---|---|
| Industry | 26.6% |
| Residential (households) | 30.6% |
| Commercial & Public | 30.3% |
| Transport | 3.5% |
Subsidies & Incentives
| Program | Type | Status | Notes |
|---|---|---|---|
| No feed-in tariff (new systems) | regulatoryChange | Not_available | No feed-in tariff for new residential systems since 2013. Export at Nordpool spot market rate. Very high grid electricity prices make self-consumption the primary value driver. |
Reference Model Results
Using our calculator with a 5 kWp system, 8,500 kWh annual demand, no battery:
| Metric | Value |
|---|---|
| Annual generation | 4,900 kWh |
| Self-consumption | 51% (2,500 kWh) |
| Export | 49% (2,396 kWh) |
| Self-consumed value | €900/year |
| Export value | €72/year |
| Gross annual saving | €972/year |
| Simple payback | 7.4 years |
| NPV (6%, 25 yr) | €3513 |
| Verdict | Excellent investment |
NPV: Net Present Value. Adds up 25 years of savings, discounted at 6%, and compares to keeping the money in the bank. Positive = solar beats the bank. Negative = you'd be better off investing elsewhere.
Battery Economics
No TOU tariff. Battery saves retail-feed-in spread only. Payback 12–16 years.
Country-Specific Considerations
Denmark has very high electricity prices but no feed-in tariff for new systems since 2013. Self-consumption is the only value. District heating is very common — many homes don't need electric heating.
Grid Connection
- Typical connection: threePhase25A
- Single-phase max: 5 kWp
- Export limit per phase: 4.6 kW
- Metering type: netTotal
- Net metering: Your generation offsets consumption across all phases (favorable)
- Net metering policy: none
Red Flags for Denmark Installers
- Quotes feed-in tariff (ended 2013) (reviewed 2026-05 — Installer claim monitoring)
- Doesn't mention district heating dominance (reviewed 2026-05 — Installer claim monitoring)
- Assumes gas heating is common (it's not) (reviewed 2026-05 — Installer claim monitoring)
- Ignores 25% VAT (reviewed 2026-05 — Installer claim monitoring)
When Solar Makes Sense in Denmark
- ✅ You have high electricity bills (above average for your country)
- ✅ You're home during the day (retired, work from home)
- ✅ You have an EV and charge at home
- ✅ You can get available subsidies
- ✅ You value energy independence
Verdict Summary
| Strategy | Payback | Notes |
|---|---|---|
| 5 kWp solar only | 7.4 years | Excellent investment |
| With battery | Add 4–8 years | Marginal — calculate carefully |
| With subsidies | Subtract 1–3 years | Check current programs |
| With EV charging | Subtract 1–2 years | Increases self-consumption |
Denmark has very high electricity prices but no feed-in tariff for new systems since 2013. Self-consumption is the only value. District heating is very common — many homes don't need electric heating.
