H1 2025: China installs more solar than rest of the world combined

H1 2025: China installs more solar than rest of the world combined

Global solar installations are breaking records again in 2025. In H1 2025, the world added 380 gigawatts (GW) of new solar capacity – a staggering 64% jump compared to the same period in 2024, when 232 GW came online. China was responsible for installing a massive 256 GW of that solar capacity.

For context, it took until September last year to pass the 350 GW mark. This year, the milestone was achieved in June. That pace cements solar as the fastest-growing source of new electricity generation worldwide. In 2024, global solar output rose by 28% (+469 terawatt-hours) from 2023, more growth than any other energy source.

Nicolas Fulghum, senior energy analyst at independent energy think tank Ember, said, “These latest numbers on solar deployment in 2025 defy gravity, with annual solar installations continuing their sharp rise. In a world of volatile energy markets, solar offers domestically produced power that can be rolled out at record speed to meet growing demand, independent of global fossil fuel supply chains.”

China’s solar dominance

China is leading this surge by a wide margin. In the first half of 2025, the country installed more than twice as much solar capacity as the rest of the world combined, accounting for 67% of global additions. That’s up from 54% in the same period last year. Developers rushed to complete projects before new wind and solar compensation rules took effect in June, fueling the spike. While that may lead to a slowdown in the second half of the year, new clean power procurement requirements for industry and bullish forecasts from China’s solar PV association (CPIA) suggest that 2025 will still surpass 2024’s record high.

The rest of the world

Other countries are adding solar at a healthy clip, too. Together, they installed an estimated 124 GW in the first half of 2025, a 15% year-over-year increase. India came in second with 24 GW, up 49% from last year’s 16 GW. The US ranked third with 21 GW, a 4% gain year-over-year despite recent moves by the Trump administration to suppress clean power deployment. Germany and Brazil saw slight dips, while the rest of the world added 65 GW, a 22% rise over 2024.

Africa’s solar market is also stirring. The continent imported 60% more solar panels from China over the past year, though a lack of reliable installation data makes it a challenge to track the true pace of deployment.

With installations surging across major markets and China driving the charge, 2025 is on track to be another record-breaking year for solar power.
