Photovoltaic panels convert sunlight into direct-current electricity, which an inverter changes into alternating current for buildings and power networks. A country’s solar generation share measures electricity produced by solar divided by electricity generated from all sources during the same period. Under an analysis of Ember’s regularly updated annual electricity dataset, seven major solar-producing countries supplied at least 18.8% of their reported electricity generation from solar in 2025.

The ranking covers countries producing at least 5 terawatt-hours (TWh) of solar electricity annually, following the large-market filter in Ember’s 2026 Global Electricity Review. Smaller electricity systems, including countries with potentially higher solar percentages, are intentionally excluded. The underlying 2025 figures were published in April, while Ember lists a further dataset refresh on November 3, 2026. The ranking therefore concerns annual generation, not the instantaneous output or solar capacity on November 8.

Top 7 by share of electricity generated

1. Hungary — 27.3% — The leader reached 27.29%, up from approximately 24% in 2024. Solar farms and rooftop generation now account for more than one-quarter of annual electricity output.
2. Chile — 25.1% — Chile’s 25.06% share places it second. Extensive desert solar development has raised daytime supplies while increasing the need for storage and grid flexibility.
3. Greece — 22.2% — At 22.17%, Greece illustrates substantial solar penetration in a Mediterranean electricity system, with growing importance for interconnections and flexible dispatch.
4. Spain — 21.9% — Spain generated 21.85% of its electricity from solar. The result complements the country’s large absolute output, about 63 TWh in Ember’s global review.
5. Netherlands — 21.1% — Despite less intense sunlight than many southern markets, Dutch rooftops and other installations delivered a 21.12% solar share.
6. Australia — 19.6% — Australia reached 19.59% and led globally in solar electricity produced per resident, according to Ember. Widespread household panels are a major factor.
7. Pakistan — 18.8% — Pakistan reached 18.77% in the reported electricity mix after rapid solar adoption. Ember notes that off-grid and behind-the-meter production complicates complete measurement.

Hungary’s share of 27.3% is about 3.1 times the global solar share of roughly 8.8%. Ember reported 50 countries above 10% solar in 2025, compared with 15 in 2020. The rapid expansion builds on the longer-term trends reviewed in BitcoinVersus.Tech’s 26-year renewable-capacity analysis. Installed gigawatts, however, are not the same measurement as terawatt-hours generated.

A different winner when ranking total electricity

Solar share and production volume answer different questions. China produced approximately 1,175 TWh of solar power in 2025, followed by the United States at 389 TWh and India at 196 TWh. None topped the seven-country share list. Their much larger national electricity systems dilute solar’s percentage even when absolute production is substantial. Related capacity figures appear in the IRENA-based capacity-growth comparison.

Why solar leaders increasingly need storage

Large midday output can push prices down and create congestion or curtailment if demand and transmission cannot absorb available electricity. Ember estimates Chile added enough battery capacity in 2025 to theoretically shift 76% of its added daily solar generation, while Australia reached 53%. Actual batteries also provide grid services beyond shifting sunlight. BitcoinVersus.Tech has examined solar farms adding batteries and large operating battery sites.

The IEA’s renewable-growth outlook shows why expanding grids matters alongside panel manufacturing. Solar-generation statistics may be revised, and distributed or off-grid production can be incompletely counted. The leading percentages measure recorded annual supply, not reliability, total carbon emissions, or the ability to run entirely on solar after sunset.

BitcoinVersus.Tech Editor’s Note

Published November 8, 2026. Rankings use 2025 annual electricity generation, limited to countries producing at least 5 TWh of solar electricity. Percentages are rounded from Ember-derived annual data; the global benchmark is approximate. The November 3 dataset refresh is not a new 2026 full-year ranking. The featured solar landscape is conceptual artwork depicting Hungary and Chile, not verified photographs of named plants.
