China’s Solar Leap from 8% to 70% Signals Major Industry Shift: Report

China’s manufacturing dominance continues to shape the global solar industry, but the sector is entering a phase of intense disruption marked by aggressive price wars and deepening margin compression.

Leading manufacturers including Jinko Solar, Trina Solar and JA Solar have reported significant financial losses amid a sharp decline in module prices. These firms—alongside LONGi Green Energy and Tongwei, which together comprise the industry’s top five—reduced their workforce by more than 30% in 2024.

A recent brief by the Center for Strategic and International Studies (CSIS) said the sector is undergoing a wave of consolidation and market exits not seen in over a decade. More than 40 smaller companies have either filed for bankruptcy, been acquired, or exited the market. The report added that Chinese regulators are actively accelerating this restructuring, with potential ripple effects across global solar supply chains.

From Cost Leader to Technology Powerhouse

China’s solar journey began as a follower in first-generation photovoltaic technologies but rapidly evolved into a global leader by refining manufacturing processes, improving efficiency, and aggressively cutting costs.

Within less than a decade, the country transitioned from traditional crystalline silicon (BSF) cells to large-scale deployment of PERC technology, and more recently to advanced TOPCon cells. The adoption of TOPCon surged from just 8% to nearly 70% of the market in three years.

By 2024, Chinese manufacturers had achieved an average conversion efficiency of 25.4% for mass-produced n-type TOPCon cells, up from 21.8% for PERC cells in 2018, according to industry data. In contrast, U.S.-based First Solar has focused on thin-film CdTe technology, improving efficiency from around 18% to 20% over the same period.

Cycles of Boom, Bust, And Consolidation

China’s solar expansion accelerated during the 2009–2010 boom, when manufacturers scaled rapidly—largely through debt—to meet surging demand in Europe and the United States.

At its peak, nearly 90% of China’s solar output was exported. However, the sector entered what analysts describe as its “darkest hour” in 2012, when U.S. anti-dumping duties and European trade probes restricted market access. The fallout forced hundreds of firms to shut down and triggered heavy losses across the industry.

Major players such as Suntech and LDK Solar collapsed under financial pressure, highlighting the risks of overcapacity and export dependence. Despite these setbacks, China rebounded and, by 2024, had established dominance across the solar value chain—including wafers, cells, and modules.

A New Crisis: Price Wars and Global Decoupling

The industry is now facing another wave of disruption, driven by oversupply and intense price competition. Module prices have fallen to historic lows, squeezing margins even for the largest manufacturers.

At the same time, geopolitical tensions are reshaping trade flows. The United States has adopted a more restrictive stance toward Chinese solar imports, implementing anti-circumvention rules targeting Chinese-linked production in Southeast Asia and enforcing the Uyghur Forced Labor Prevention Act. These measures include detaining shipments over supply chain compliance concerns, effectively decoupling the U.S. market from Chinese supply chains.

In contrast, Europe has attempted to strike a balance between protecting domestic industry and maintaining access to affordable solar components.

Strategic Shift Toward Intermediate Exports

In response to these restrictions, China is increasingly shifting its export strategy toward intermediate products such as wafers and cells rather than finished modules. This approach allows Chinese firms to navigate trade barriers more effectively and align with European Union diversification requirements while trying to maintain global market access despite tightening restrictions. 

Export patterns are also evolving geographically. While the European Union remains the largest market by value, its share is declining. Meanwhile, demand is rising rapidly in the Asia-Pacific and Middle East regions, which are absorbing a growing share of Chinese solar exports.

Global Expansion and Embedded Supply Chains

Chinese companies are also expanding overseas manufacturing to adapt to changing tariff regimes. Investments in countries such as Indonesia, Vietnam, Malaysia, and Saudi Arabia are helping firms meet local content requirements while building regional supply chains.

This strategy is embedding Chinese companies deeper into global markets—not just as exporters, but as developers of integrated solar ecosystems that include manufacturing, project development, and operations.

Patent Leadership and Next-Generation Technologies

China’s technological edge is increasingly reflected in its dominance in intellectual property. By 2024, the country accounted for roughly 65% of global solar patent applications, according to industry estimates.

Advances in next-generation technologies—particularly perovskite and tandem cells—are further strengthening this lead. For instance, LONGi Green Energy has achieved a record conversion efficiency of 34.85% in perovskite-silicon tandem cells, as reported by the National Renewable Energy Laboratory.

State-Driven Innovation Ecosystem

China’s solar leadership is underpinned by a coordinated, multi-layered innovation system. The central government also sets a strategic direction, to provide funds Research and Development (R&D), and provides subsidies. 

Additionally, China’s provincial governments also offer targeted incentives and specialization. The report noted that the different component offered by different talent-rich and research-intensive major hubs in China such as: 

• • Guangdong: perovskite and tandem technologies

  • Zhejiang: module efficiency

  • Jiangsu and Anhui: manufacturing support

  • Beijing and Shanghai: research-driven innovation

Private firms play a dominant role, accounting for over 75% of solar patent applications. Leading companies are pursuing vertical integration across wafers, cells, and modules, while mid-tier firms are specializing in niche segments—such as Sungrow in inverters and Xinte Energy in polysilicon.

Reshaping the Global Solar Order

The ongoing turbulence in China’s solar sector reflects not just a cyclical downturn, but a structural transformation of the global industry. While price pressures are forcing consolidation at home, China’s continued advances in technology, manufacturing scale, and global integration are reinforcing its leadership position.

At the same time, trade barriers and geopolitical shifts are fragmenting markets, pushing other regions to rethink their strategies. The result is an increasingly complex and competitive global solar landscape—one in which China remains central, even as the rules of competition continue to evolve.
