China’s Solar Boom: Growth, Challenges, and the Future

Rapid Expansion in the 14th Five‑Year Plan

From 2021 to 2025 China’s photovoltaic (PV) industry has surged:

• Annual output value topped 1 trillion yuan (about US$147 billion).
• Exports exceeded US$180 billion.
• Cumulative installed capacity passed 1,200 GW.
• PV modules reached more than 200 countries and regions.

New Pressures in Overseas Markets

Since 2024 Chinese solar products have faced tougher competition abroad:

• Export volumes keep rising, but sale prices are falling.
• Some firms engage in aggressive low‑price selling, squeezing profits.
• This raises the risk of anti‑dumping or countervailing duty investigations.

Policy Shift: Ending Export Tax Refunds

On April 1 2026 China removed export tax rebates for PV goods. Experts say this will:

• Discourage pure scale‑driven expansion.
• Push companies toward technology upgrades, brand building, and smarter products.
• Help phase out outdated capacity and stabilise overseas prices.

How Leading Firms Are Going Global

Ronma Solar’s Smart Factory

In Jinhua, Zhejiang, robotic arms and automated systems turn silicon wafers into panels. Executive Xiao Yuanbiao notes new orders from Central and Southeast Asia are boosting production.

Astronergy’s Localised Approach

Vice‑president Huang Haiyan explains that true globalization means more than selling abroad:

• Setting up factories in target countries.
• Offering full value‑chain solutions—modules, storage, construction.
• Example: a solar‑plus‑storage project in Turkey supplied entirely from Astronergy’s local plant.

Provincial Support and Industry Self‑Discipline

Zhejiang, a PV hub, has seen rapid capacity growth since 2023, leading to “involution”‑style competition. To counter this, the province introduced policies promoting:

• Industry self‑discipline.
• Production capacity control.
• Shift toward higher‑value, intelligent manufacturing.

Digitalisation at Astronergy’s Haining Base

Plant manager Pang Shaohua describes a “PV manufacturing plus internet” model launched in 2016:

• AI‑assisted inspection cut workforce needs from eight to two workers per four lines.
• Inspection efficiency quadrupled.

Innovative “PV‑Plus” Applications

Fishery‑Solar Project in Wenzhou

Offshore solar panels above fish farms generate extra income—about US$443 per mu each year—and create over 1,000 jobs.

Forest‑Solar Medicinal‑Yew Demonstration

In Taishun County, panels shade yew trees, bringing the village roughly US$29,500 annually and supporting a tourism program with aerial views of the arrays.

Looking Ahead

Shen Fuxin of the Zhejiang Solar Energy Industry Association sees future growth in:

• Replacing small, old systems with larger, more efficient ones.
• Upgrading aging installations.
• Expanding PV‑plus scenarios like aquaculture, forestry, and tourism.

These steps can ease pressure from overcapacity and drive a healthier, technology‑focused market.

Conclusion

China’s PV sector has grown explosively, but falling prices and trade tensions show that size alone isn’t enough. Recent policy changes, smarter factories, and creative PV‑plus projects point toward a future where innovation, quality, and localised value chains lead the way. For teens interested in clean energy, China’s solar story offers a clear lesson: sustainable success comes from balancing growth with smarter, greener technology.
