Solar Installation Cost per kWp in Europe by Country

Last updated: November 2026

Quotes for the same 10 kW roof can differ by thousands of euros between countries, and national surveys do not measure cost the same way. This guide puts the official figures for eight European countries side by side, with the year, tax basis and scope each one uses, so you can tell a real price gap from a reporting difference.

Solar Installation Cost per kWp in Europe: Country Table

All figures come from official statistics or national survey reports. The year and the tax basis differ by country, so read the last two columns before you compare rows. The IEA PVPS reports quote prices in euros per watt of installed PV capacity; the table converts them to €/kWp by multiplying by 1,000.

Residential rooftop systems (about 5 to 10 kW)

The United Kingdom and Poland rows stay in their own currencies. DESNZ publishes costs per kW of total installed capacity (TIC), and also per declared net capacity (DNC), which is usually lower in capacity and so higher in cost per kW. The DESNZ page says average costs based on TIC are typically 6 to 12% lower than costs per DNC.

Commercial, industrial and utility-scale systems

Sources: the same IEA PVPS reports, the DESNZ statistics and the IEO summary as above. Belgium’s 2024 report gives €1,000/kWp for 10 to 100 kW, €700 to €800/kWp for 100 to 750 kW and €600 to €650/kWp for 750 kW to 20 MW, without a tax basis for those rows.

Which European Country Has the Cheapest Solar Installation per kWp?

On the euro-priced sources above, Germany reports the lowest residential range, €900 to €1,500/kWp at the end of 2025. The UK and Poland rows are in other currencies and are not ranked. The Netherlands (an estimated €1,200 in 2023), Italy (€1,200 to €1,600 in 2024) and Spain (€1,400 in 2023) sit close behind. France reports the highest, at €2,300 for 5 to 10 kW in 2024. Years and tax bases differ, so use the table to pick the countries to quote in, then compare dated quotes for your own project.

What Goes Into the Price

Two national surveys publish a cost breakdown for a 5 to 10 kW residential system. Costs are in €/W, excluding VAT, and the shares are calculated from the survey totals.

Italy’s survey is by GSE, and its “permits and commissioning” line includes financing. France’s mounting figure is 0.25 and other electronics 0.18, shown here combined, and its soft costs (planning, installation work, shipping, permits and margin) are reported as one 0.56 subtotal. The France shares are calculated on the sum of the listed lines, 1.87, because the survey’s own total of 1.9 is rounded. The France report also gives €2.3/W for the same segment in its price-trend table and does not reconcile the two figures. The France survey says that as module and inverter prices fell, the cost of mounting structures and installation rose. Sources: IEA PVPS Italy 2024 and IEA PVPS France 2024.

The component shares differ between countries, so one set of percentages does not fit every quote. A complex roof or a long grid connection can justify a higher price in the same market.

Utility-Scale Solar Cost per kWp and per kWh

For large PV plants, Fraunhofer ISE’s July 2026 report uses IRENA data, converted to euros, to give a global weighted-average total installed cost of €595/kWp in 2025, with the 5th to 95th percentile range at €341 to €1,079/kWp. The global weighted-average levelized cost of electricity (LCOE) for large PV systems was €0.040/kWh in 2025, with a range of €0.025 to €0.086/kWh. For Germany, the same report gives an LCOE of 4.1 to 5.0 euro cents per kWh for PV power plants in 2024 and says the total installed cost of German utility-scale systems rose by about 40% on the previous year. Source: Fraunhofer ISE Photovoltaics Report, 14 July 2026.

Cost per kWp measures what you pay for capacity. LCOE depends on yield, financing and lifetime too, so a plant with a low €/kWp can still have a high €/kWh in a cloudy region.

How Costs Have Changed Since 2023

• Italy: the typical price for under 10 kW fell from €1.45/W in 2023 to €1.39/W in 2024, about 4%, excluding VAT.
• France: the 5 to 10 kW average fell from €2.5/W in 2023 to €2.3/W in 2024. Typical module prices fell from €0.15 to €0.30/Wp in 2023 to €0.09 to €0.22/Wp in 2024.
• United Kingdom: the median for 0 to 4 kW systems fell from £1,910/kW in 2023/24 to £1,667/kW in 2024/25 and £1,595/kW in 2025/26 (not adjusted for inflation).

Module prices fell faster than installed prices. Do not apply a module price drop to a full quote: the France survey says mounting, installation and permitting costs rose while module and inverter prices fell. See the solar module price forecast for 2026 to 2028 for module trends.

Calculate Installed Cost per kWp

Installed cost per kWp = installation cost ÷ installed PV DC nameplate capacity.

Use module nameplate power at standard test conditions for the denominator. Do not use inverter AC rating, export limit or annual energy. See the kilowatt-peak definition.

Worked example. A 10 kWp system is quoted at €15,000 including the stated tax, with no battery and no subsidy deducted. That is €15,000 ÷ 10 = €1,500/kWp. If a €2,000 grid-connection charge sits outside the quote, the project cost is €17,000, or €1,700/kWp. The difference is scope, not a higher installer margin. State both figures when the boundaries differ.

Make Every Quote Cover the Same Items

Ask each installer to mark every line as included, excluded, provisional or supplied by someone else.

A quote can be sound and still leave items out. The trouble starts when the exclusions are hidden. The word “turnkey” does not guarantee the same scope from every bidder.

Keep Battery Costs Out of the PV-Only Figure

Divide only the PV subtotal by PV kWp. A quote with a battery, divided by PV kWp, answers a different question. Show the PV subtotal, the battery package and the project total on separate lines. For storage, give battery energy in kWh and power in kW, say whether the capacity is nameplate or usable, and list what the price includes: inverter, controls, backup switching, wiring, installation and commissioning.

A wholesale price per kWh for cells or packs is not an installed home-storage price.

Tax, Currency and Incentives

Compare gross and net prices on purpose. Record whether tax is included, whether the buyer can recover it, and which items qualify for any reduced rate. The table above shows why: Italy and France are excluding VAT, Belgium and the UK include it, and some sources do not say.

Keep each source currency visible. If you convert to euros, note the exchange-rate source and date. List incentives on their own line, apart from the pre-incentive invoice, and mark whether each is approved or only assumed.

From Cost per kWp to a Financial Decision

Cost per kWp does not tell you the cost of a kWh or the bill savings. Use a documented solar yield prediction and the same system boundary in the financial model. Value self-consumed and exported electricity separately, and include running costs.

A basic screen is simple payback = net investment ÷ annual net benefit. With €15,000 invested and an assumed €1,500 a year of net benefit, that is 10 years. The €1,500 is an illustrative input, not a market tariff. Simple payback ignores discounting, financing, tariff changes, degradation and replacements, so use the NPV, IRR and payback guide for a fuller comparison.

A Quotation Worksheet You Can Copy

For every offer, record:

1. Country, location, project type and the quote date and validity.
2. PV DC capacity, inverter AC rating and any export limit.
3. Pre-tax, tax-inclusive and complete project totals.
4. Separate lines for storage, grid works, roof works and recurring costs.
5. Currency and any conversion date and rate.
6. Incentives as separate assumptions, with approval status.
7. Equipment, yield basis and financial inputs.

Fill every gap before you compare totals, and keep an allowance visible for anything still unpriced. For prices outside Europe, see the guides to 5 kW solar panel prices in India and solar panel installation cost in India.

Frequently Asked Questions

Which European country has the cheapest solar installation per kWp?

On the euro-priced sources in this guide, Germany reports the lowest residential range: €900 to €1,500/kWp for a 10 kWp rooftop system at the end of 2025. The Netherlands (an estimated €1,200 in 2023), Italy (€1,200 to €1,600 in 2024) and Spain (€1,400 in 2023) are close. France reports €2,300 for 5 to 10 kW in 2024. Years and tax bases differ.

How much does a 10 kWp solar system cost in Germany in 2026?

Fraunhofer ISE’s July 2026 report lists €900 to €1,500/kWp for a 10 kWp rooftop system at the end of 2025, which is €9,000 to €15,000 for 10 kWp. Get a current quote for your roof, because grid connection, access and tax treatment change the total.

Why do solar installation costs differ between European countries?

Equipment, labour, roof type, permits, grid connection and tax all differ. France’s survey puts the average 5 to 10 kW system at €2.3/W and Italy’s at €1.39/W. The breakdowns show most of the gap in hardware: €1.3/W in France against €0.86/W in Italy.

What does the cost per kWp include?

It depends on the source or quote. Check modules, inverter, mounting, wiring, labour, access, engineering, permits, grid works and commissioning. List batteries, roof works, recurring charges and tax on separate lines.

How have solar installation costs in Europe changed since 2023?

They have fallen in the countries with data. Italy’s under-10 kW price fell about 4% from 2023 to 2024, France’s 5 to 10 kW average fell from €2.5/W to €2.3/W, and the UK median for 0 to 4 kW systems fell from £1,910/kW in 2023/24 to £1,595/kW in 2025/26.

Does cost per kWp fall for larger commercial systems?

Yes, large systems cost less per kWp than residential ones in every national survey above, though not in a straight line. In Italy the price falls from €1,200 to €1,600/kWp under 10 kW to €800 to €1,100/kWp above 250 kW, and in France from €2,300 to €900 (France’s over-250 kW rooftop figure is above its 10 to 100 kW figure of €800). Roof complexity and grid works can still move a specific quote.

What is the cost of utility-scale solar per kWh?

The global weighted-average LCOE for large PV systems was €0.040/kWh in 2025, within a range of €0.025 to €0.086/kWh, according to IRENA data in Fraunhofer ISE’s July 2026 report. Germany’s PV power plants had an LCOE of 4.1 to 5.0 euro cents per kWh in 2024.
