Solar Photovoltaic Generation by EU Country

Key Takeaways

• Hungary posted the EU’s highest photovoltaic share of total electricity generation in March 2026, at 30.3%. It ranked eighth in absolute solar photovoltaic volume, with 976 GWh.
• Germany generated more solar photovoltaic electricity than any other EU country in March 2026, at 8,746 GWh. Its photovoltaic share of total generation, 21.3%, ranked fourth. 
• Finland recorded the EU’s lowest photovoltaic share of total electricity generation in March 2026, at 0.8%.
• A country’s photovoltaic share depends on the size of its total electricity system as much as the size of its solar photovoltaic fleet. Solar photovoltaic supplied 13.5% of total electricity generation across the EU’s 27 member states in March 2026. That works out to 32,328 GWh out of a 240,275 GWh total.
• Solar photovoltaic capacity grew from 338 GW in 2024 to 406 GW in 2025. Solar became the EU’s single largest electricity source for the first time in June 2025, at 22.0% of total generation that month.

Hungary generated less solar photovoltaic electricity in March 2026 than Italy, Spain, or Poland. Yet solar made up a bigger share of Hungary’s electricity than anywhere else in the EU that month. Solar photovoltaic supplied 976 GWh in Hungary, out of 3,222 GWh generated nationwide. That works out to a photovoltaic share of 30.3%.

Germany tells the opposite story. It generated almost nine times as much solar photovoltaic electricity, at 8,746 GWh. However, its share of total generation came to just 21.3%. That ranks below three countries with far smaller solar photovoltaic fleets.

The difference between Hungary and Germany comes down to the size of their total electricity generation, not the size of each solar photovoltaic fleet.

• Hungary: 3,222 GWh. That is among the smallest in the table.
• Germany: 40,987 GWh.

A modest volume of solar photovoltaic generation moves the percentage further when the total is small. That is why Hungary’s share comes out so high relative to its solar volume.

Germany still posts a respectable 21.3% share. The reason is a genuinely large solar photovoltaic fleet, not a small electricity grid.

The rest of the top tier shows both patterns side by side:

• Estonia: 132 GWh of solar photovoltaic, 454 GWh total, 29.0% share
• Netherlands: 2,227 GWh of solar photovoltaic, 10,431 GWh total, 21.4% share
• Belgium: 1,110 GWh of solar photovoltaic, 5,207 GWh total, 21.3% share
• Latvia: 154 GWh of solar photovoltaic, 765 GWh total, 20.1% share

March 2026 Sits Inside a Broader EU Solar Photovoltaic Boom

This single month sits inside a longer EU-wide trend. Solar photovoltaic capacity reached 406 GW in 2025. In 2024, it was just at 338 GW. Falling panel costs and EU renewable energy policy are driving that growth. The European Commission’s 2022 Solar Energy Strategy set a target of 380 GW by 2025. The EU has already exceeded it.

EU-wide electricity data show solar became the EU’s single largest electricity source for the first time in June 2025. It supplied 22.0% of total EU electricity that month. That edged out the EU’s next three largest sources:

• Nuclear power: 21.6%
• Wind power: 15.8%
• Hydro power: 14.1%

A stretch of unusually hot, sunny weather that month pushed solar output to a seasonal record. June also sits near the peak of the EU’s solar season, when daylight hours are longest. That ranking is unlikely to hold through the shorter days of winter.

Solar’s role within the EU’s renewable mix has grown just as sharply over a longer span. This is a different measure from the photovoltaic share of total generation shown in the table. EU renewable energy statistics show solar supplied 23.4% of the bloc’s renewable electricity in 2024, up from roughly 1% in 2008. That is a more than twentyfold increase. The same forces behind the capacity boom, falling costs, and binding EU renewable energy targets explain this longer climb.
