China has built the world’s largest green energy machine and is now discovering how expensive that dominance can be. The country’s solar and wind complex is losing roughly $60 Billion a year on paper, yet capital keeps pouring in and capacity keeps climbing. The result is a paradox that defines the global energy transition: a system that is both financially distressed and strategically irresistible.
Investors are not walking away from this burn rate, they are doubling down on it. From record solar installations at home to aggressive clean-tech spending abroad, China is treating short term losses as the price of long term control over the technologies that will power the next industrial era.
The $60 Billion hole behind record solar growth
The starting point for understanding the current crunch is the sheer scale of China’s solar buildout. The country added a record 277 g of solar capacity in 2024, a figure that would have been unthinkable a decade ago and that now shapes global supply, pricing and manufacturing decisions. That surge has collided with collapsing panel prices and brutal competition, leaving the solar industry “bleeding out” financially even as physical installations keep rising and the sector racks up an estimated $60 Billion in annual losses according to detailed assessments of the solar industry.
Those losses are the flip side of a deliberate strategy that has flooded the world with cheap panels. Analysts tracking global deployment expect installations in China to crest at 372 G of new solar capacity in 2025 before growth slows, a peak that underscores how far the country has pushed its manufacturing base and domestic grid to absorb new projects. Forecasts from BNEF suggest that even a slowdown will leave China adding more capacity than any other market, locking in its role as the price setter for solar hardware and the main shock absorber for global oversupply.
Overcapacity, bankruptcies and the cost squeeze
Behind the headline numbers, the economics of this buildout are punishing. Years of state-backed expansion have created a glut of factories and modules, and the same low prices that made solar ubiquitous are now crushing the companies that produce it. Industry observers describe how China’s push for scale has driven module prices so low that a Wave of Bankruptcies has swept through the Solar Sector China, with weaker manufacturers unable to cover costs or refinance debt in a market where margins have been shaved to near zero.
Even the strongest players are feeling new pressure from input costs they cannot control. The price of silver, a critical material for photovoltaic cells, has more than tripled in the past year, a spike that has hit Chinese producers just as they were cutting selling prices to defend market share. Analysts note that some projects have already been delayed or cancelled in 2025, with developers citing steep silver costs as a key reason, a reminder that the sector’s fate is tied not only to policy and demand but also to volatile commodity markets that can suddenly turn a tight margin into a loss, as highlighted in recent coverage of silver costs.
Why investors keep writing checks
Given that backdrop, the persistence of investor appetite looks less like irrational exuberance and more like a calculated bet on long term dominance. China’s top solar companies, including Longi and Trina, have been at the center of what analysts describe as a Solar Overbuild Turns Into a Billion Meltdown, yet they continue to attract financing because they anchor a supply chain that policymakers see as strategically vital. Reports on the Solar Overbuild Turns describe how local governments have been slow to rein in capacity, even as profits evaporate, because they view these firms as national champions in a global technology race.
Capital is also flowing into the infrastructure that will eventually make better use of all this generation. One of the country’s major grid operators, China Southern Power Grid, is planning a record spending program in 2026 that will channel roughly 50 percent of its budget into projects tied to clean energy integration and reliability upgrades. The company has outlined a $26 billion investment plan that includes ultra high voltage lines and digital grid controls, a sign that state owned utilities are being asked to absorb some of the strain created by intermittent renewables and to prepare for even more capacity, as detailed in planning documents from China Southern.
A grid that cannot keep up
The financial pain is compounded by a structural problem: the grid is not yet capable of using all the clean power being produced. China has built the world’s biggest solar and wind power capacity, but the electricity grid cannot use it efficiently, leading to Curtailment of output that leaves turbines idle and panels disconnected even when the sun is shining and the wind is blowing. Critics argue that this under utilisation of renewables in favour of coal reflects both technical bottlenecks and entrenched interests in the fossil fuel sector, a tension captured in detailed accounts of how Curtailment has become a persistent feature of the system.
At the same time, the country is racing to upgrade and repower its existing renewable fleet. Many of the earliest wind farms are now more than a decade old, and analysts tracking global infrastructure trends note that the repowering of wind assets is becoming a necessity as operators swap out older turbines for more efficient models. China’s renewable energy buildout is increasingly intertwined with a maturing battery storage market, which is expected to play a central role in smoothing out the variability of solar and wind and in reducing the need for curtailment, according to assessments of wind assets and storage trends.
Global expansion as pressure valve
One reason investors are willing to tolerate domestic losses is that Chinese firms are increasingly treating the world as their growth market. Chinese companies have committed roughly $80B to clean-tech projects abroad, targeting regions where demand for new capacity is rising and local manufacturing bases are weaker. The Middle East and North Africa, for instance, are seeing a surge in Chinese backed solar and wind investments as governments there try to lower reliance on fossil fuels, with some individual projects larger than Australia’s total installed capacity, according to detailed tallies of Chinese overseas spending.
Policymakers in Beijing appear to view this global push as a way to offset domestic headwinds. Analysts at Moody argue that China’s global investment surge aims to counter domestic challenges, with capital flowing into emerging markets where growth prospects are stronger and where Chinese technology can lock in long term influence over energy systems. That logic extends beyond generation to transmission, storage and even electric vehicle supply chains, turning the current losses at home into a kind of down payment on future geopolitical leverage, as described in recent assessments of China and its outward investment strategy.
