Global solar manufacturing capacity is projected to reach an impressive 1.8 terawatts (TW) by 2025, with China accounting for a significant 75% of this capacity, according to a recent report by the International Energy Agency (IEA).
China’s Role in Global Solar Manufacturing Capacity
The report underscores China’s overwhelming dominance in the solar supply chain, with the country controlling most of the raw materials, components, and equipment needed for solar production. Despite global efforts to diversify the supply chain, China’s share of global solar manufacturing capacity remains substantial. This dominance is complemented by China’s strategic investments and policies that have bolstered its position as a leader in the solar industry.
However, the report also highlights a 60% increase in global solar manufacturing capacity since last year, with notable expansions in countries such as the United States and India. This growth is driven by increased investment in solar manufacturing, with over $80 billion invested in new capacity in the first half of 2024.

Challenges and Opportunities Shaping Solar Manufacturing Capacity
The IEA report identifies several challenges facing the solar supply chain, including rising material costs, labor shortages, and logistical issues. Nevertheless, it also points to opportunities for innovation and cost reduction, such as the development of new materials and manufacturing techniques. Despite these challenges, the IEA remains optimistic about the future of solar energy, forecasting that global solar capacity will reach 1.8 TW by 2025.
A significant challenge outlined in the report is the rising cost of materials used in solar manufacturing. The price of polysilicon, a critical component in solar panels, has surged due to rising demand and supply chain disruptions. Additionally, the cost of other materials like aluminum and copper has increased, pressuring solar manufacturers to explore cost-reduction strategies.
Another major challenge is the shortage of skilled labor required to install and maintain solar systems, which is impeding the deployment of new solar capacity. The report advocates for increased investment in training and education programs to address this shortage and ensure the solar industry has the workforce it needs for continued growth.
Global Solar Manufacturing Capacity: Future Outlook and Industry Impacts
Despite these challenges, the report highlights several opportunities for innovation in the solar industry. Key areas of focus include developing new materials and manufacturing techniques that could help reduce costs and improve solar panel efficiency. For example, researchers are exploring perovskite materials, which could potentially replace silicon in solar cells, thereby reducing the cost of solar panels.
Overall, the IEA’s report presents a balanced view of the future of solar energy. While significant challenges exist, there are also ample opportunities for innovation and expansion. As countries worldwide continue to invest in solar energy, the IEA anticipates that global solar capacity will continue to grow, aiding the shift to a clean energy future.
The report underscores the necessity for sustained investment in solar energy and the importance of addressing the challenges within the solar supply chain. With appropriate policies and investments, the solar industry could play a pivotal role in the global transition to clean energy. As the world progresses towards a more sustainable future, solar energy will be a crucial element of the global energy mix, contributing to reduced greenhouse gas emissions and the fight against climate change.
