• BloombergNEF has cut its 2026 global solar installation forecast to 584 GW DC, 10.8% below its 655 GW estimate for 2025 and the first annual decline in PV deployment on record.
  • China is driving the downturn: installations are expected to fall 29% to 271 GW in 2026, with first-half additions down 66% year on year, while the rest of the world grows 13% to 313 GW.
  • BNEF analyst Jenny Chase attributes the slowdown to market saturation rather than politics or pricing, and expects a recovery to 618 GW in 2027.

Global solar deployment is heading for its first annual contraction in history, with BloombergNEF slashing its 2026 solar installations forecast to 584 GW DC, according to reporting by pv magazine USA. The new figure sits 10.8% below BNEF’s 655 GW estimate for 2025 and nearly 29% below the 753 GW that was projected for 2026 in early 2025. After more than two decades of near-uninterrupted growth, the solar industry’s defining story of 2026 will be one of digestion, not expansion.

The revision is the third downward cut in a row. At a China Photovoltaic Industry Association seminar in the first quarter of 2025, BNEF analyst Youru Tan pegged 2026 installations at 753 GW. By December 2025, that had been trimmed to 649 GW. This month’s 584 GW is the lowest of the three. It marks the first time the world’s leading clean-energy research firm has forecast an outright year-on-year decline in global photovoltaic deployment. For an industry that has doubled capacity roughly every three years for most of this century, a 10.8% contraction is a psychological break as much as a statistical one.

China drives the 2026 solar installations forecast down

The global number is really a China story wearing a global disguise. BNEF now expects China to install 271 GW in 2026, down from 383 GW in 2025. That 29% collapse accounts for the entirety of the worldwide decline, and then some. The downgrade is stark against the firm’s own fourth-quarter 2025 forecast, which still had China at 341 GW for 2026.

The first-half data explains why the forecasters blinked. China installed roughly 71.8 GW in the first six months of 2026, versus 212.2 GW in the same period of 2025, a 66% plunge that blew past even the pessimistic end of the prediction range. Two forces collided: a policy shift that ended the rush to beat subsidy deadlines, and a new five-year plan that moves the national focus from raw capacity additions toward energy storage integration. A country that routinely installed more solar in a quarter than most nations install in a decade simply stopped building at its old pace.

Chase, BNEF’s veteran solar analyst, is blunt about what is not behind the slowdown. “Honestly, none so far, a big theme has been no major booms. I don’t think it has anything to do with Chinese politics or pricing,” she said. Instead, she attributes the deeper-than-expected deceleration to saturation: grids, land availability, and project pipelines have filled faster than new demand can absorb. Back in December 2025 she had already warned that China’s growth “cannot continue at its historical breakneck pace.” The 2026 numbers are that warning coming true. The same saturation logic explains why BNEF does not see batteries or electric vehicles rescuing the demand curve: “We doubt that either batteries or EVs will halt this, they just slow it down a little.”

Global solar capacity 2026: growth shifts outside China

Strip China out of the picture and the global solar capacity 2026 outlook looks notably healthier. Installations outside China are projected to rise from 272 GW in 2025 to 313 GW in 2026, a 13% increase that slightly outperforms BNEF’s earlier 308 GW estimate for that cohort. The industry is not shrinking everywhere; it is rebalancing.

BNEF’s 2025 actuals versus 2026 forecast: China against the rest of the world. Figures reported by pv magazine from BNEF’s forecast data.
Region 2025 (GW) 2026 forecast (GW) Change
China 383 271 −29%
Rest of the world 272 313 +13%
Global total 655 584 −10.8%

The growth is broad and, for the first time in years, genuinely distributed. India continues its utility-scale buildout, while the Philippines, Nigeria, and Malaysia are emerging as meaningful new markets. Notably, growth in Nigeria and the Philippines is coming almost entirely from residential and commercial rooftop systems rather than utility-scale plants. It is a reminder that solar’s expansion frontier is increasingly about distributed generation in emerging economies rather than mega-projects in deserts. For a deeper look at how the technology itself works, see our explainer on solar panel fundamentals.

Other forecasters are telling a similar story, albeit with different numbers. SolarPower Europe’s Global Solar Market Outlook 2026–2030 estimates 664 GW installed globally in 2025, with its medium scenario pointing to an 8% dip to 612 GW in 2026, including a 24% decline in China. The direction is consistent across research houses even where the exact totals differ: China contracts sharply, the rest of the world advances modestly, and the net is the industry’s first down year.

A down year for makers, a discount year for buyers

A shrinking headline market does not mean a collapsing industry. Module prices are already near record lows, and a demand trough in 2026 would put further downward pressure on equipment costs. For anyone financing projects — from utility developers to the community-solar models taking shape in the United States — that is good news. New York’s 565 MW affordable-solar push and South Carolina’s $815 million solar financing package show the kind of distributed projects that keep getting built even when the global number dips.

Manufacturers face a tougher year. Overcapacity in the Chinese supply chain, already severe, gets worse when domestic demand falls 29%. Expect another round of consolidation among module makers. Everyone else gets cheaper panels. Equipment cost declines also improve the economics of solar-plus-storage hybrids, which is precisely where China’s policy attention is now shifting.

584 GW in context: a trough, not a turning point

The China solar installations decline deserves to be read against the industry’s own history, not against the panic of a single down year. Consider the revision sequence: 753 GW projected in early 2025, 649 GW by December, 584 GW today. Each cut has been driven almost entirely by Chinese data: first-half installations fell 66% while the rest of the world actually beat its forecast by about 2% (313 GW realized projection versus 308 GW expected). This is a forecast about one country’s policy cycle, not a verdict on solar’s long-run economics.

The “first annual decline in decades” framing also needs the right denominator. A 584 GW market is still roughly 90% of what the world installed in the record year of 2025, and it exceeds the 2024 total by a wide margin. If a marathon runner sets a personal best and then runs 10% slower the next race, nobody declares running dead. The deeper signal in the data is geographic: solar’s growth engine is migrating from Chinese utility-scale dominance toward distributed systems across India, Southeast Asia, and Africa, markets that add resilience to the industry rather than concentration risk. BNEF expects installations to recover to 618 GW in 2027, according to BNEF, which would make 2026 look like a trough, not a turning point.
