Lithuania Solar & Battery Guide
Quick Verdict
Solar panels: Excellent investment Payback 9.7 years (reference model: 5 kWp, 8,500 kWh demand, no battery).
Batteries: Marginal — calculate carefully.
Key insight: Solar economics in this country depend on the combination of electricity prices, solar yields, and available subsidies. Use the calculator for a personalized assessment.
Key Statistics
Electricity Prices (2025–2026)
| Tariff | Price | Notes |
|---|---|---|
| Standard residential | €0.28/kWh | Flat rate — same price 24/7 |
| Feed-in (export) | €0/kWh | What the grid pays for excess solar |
| Gas | ~€0.1/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 |
|---|---|---|
| Lithuania (average) | 990 kWh/yr | 4,950 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.
Lithuania has moderate solar potential. Typical for Central/Northern Europe.
Electricity Generation Mix
Understanding how Lithuania generates its electricity helps explain why solar is (or isn't) incentivised.
| Source | Share |
|---|---|
| Natural Gas | 16.5% |
| Oil | 5.8% |
| Wind | 44.9% |
| Solar PV | 18.8% |
| Biofuels | 10% |
Source: Our World in Data (2025). Total generation: 9 TWh.
High renewable penetration: Lithuania 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 | 30.6% |
| Residential (households) | 28.5% |
| Commercial & Public | 30.7% |
| Transport | 0.9% |
Subsidies & Incentives
| Program | Type | Status | Notes |
|---|---|---|---|
| Household/SME Solar Grant | grant | Active | Up to 30% investment grant for households/SMEs (≤10 kW), max €3,230. Climate Change Programme (EU ETS revenue funded). |
| Business CAPEX Programme | grant | Active | €18M CAPEX programme (2025) for business storage/PV, up to 30% funding. |
| Net Metering | net-metering | Active | Net metering for households and non-profits up to 10 kW. 2-year rolling settlement period (April–March). |
| Remote Solar Parks | other | Active | Households can buy shares of remote solar parks. |
Reference Model Results
Using our calculator with a 5 kWp system, 8,500 kWh annual demand, no battery:
| Metric | Value |
|---|---|
| Annual generation | 4,950 kWh |
| Self-consumption | 50.7% (2,510 kWh) |
| Export | 49.3% (2,436 kWh) |
| Self-consumed value | €693/year |
| Export value | €0/year |
| Gross annual saving | €693/year |
| Simple payback | 9.7 years |
| NPV (6%, 25 yr) | €919 |
| 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
Battery viability depends on whether time-of-use tariffs exist and the retail-to-feed-in price spread. Check the electricity price table above.
Country-Specific Considerations
Solar economics in this country depend on the combination of electricity prices, solar yields, and available subsidies. Use the calculator for a personalized assessment.
Grid Connection
- Typical connection: singlePhase25A
- Single-phase max: 5 kWp
- Export limit per phase: 5 kW
- Metering type: netMetering
- Net metering policy: net metering for households up to 10 kW. 2-year rolling settlement.
Red Flags for Lithuania Installers
- Promises payback significantly shorter than our model shows (reviewed 2026-05 — Installer claim monitoring)
- Doesn't mention actual feed-in/export rates (reviewed 2026-05 — Installer claim monitoring)
- Uses optimistic self-consumption (>70%) without battery or EV (reviewed 2026-05 — Installer claim monitoring)
- Doesn't include inverter replacement cost (reviewed 2026-05 — Installer claim monitoring)
- Doesn't include maintenance costs (reviewed 2026-05 — Installer claim monitoring)
- Pressure tactics ('subsidy ends soon!') (reviewed 2026-05 — Installer claim monitoring)
- Quotes without seeing your actual bills (reviewed 2026-05 — Installer claim monitoring)
When Solar Makes Sense in Lithuania
- ✅ 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 | 9.7 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 |
