The primary products manufactured in Vietnam’s solar sector include photovoltaic modules, monocrystalline and polycrystalline silicon bars, solar wafers, and thin-film solar cells. With increasing global demand for solar energy solutions, Vietnam’s solar manufacturing industry is poised for further growth, reinforcing its role as a crucial supplier in the international renewable energy market.

Japanese Investment in Solar Cell Manufacturing

Japan has been one of Vietnam’s largest foreign direct investors for many years, but its presence in the country’s solar cell manufacturing industry has been relatively limited. While Japanese enterprises have been active in Vietnam’s broader renewable energy sector, their direct involvement in solar cell production remained minimal. However, in recent years, Japan has been steadily increasing its influence in this industry, leveraging its advanced technology and strong capital investment to expand its footprint.

A key recent investment is Vsun Solar, a subsidiary of Japan’s Fuji Solar, which has been expanding its presence in Vietnam. In November 2023, the company inaugurated the first phase of its $200 million solar cell factory in Phu Tho province, with an annual capacity of 4 GW. The second phase is expected to be completed in 2024, further enhancing Vietnam’s production capabilities. Additionally, in April 2024, Vsun Solar started producing its first silicon wafer at its Vietnam facility, completing an integrated production chain for solar panel manufacturing.[6]

Another major player is Sunergy, a Japanese-backed company, which is developing a $30 million solar cell manufacturing plant in Hung Yen province. Spanning 2.65 hectares in Minh Quang Industrial Park, the facility will have an annual capacity of 600 million silicon wafers, a critical component in solar cells. Set to begin operations in June 2025, it is expected to create around 1,000 jobs, further integrating Japan into Vietnam’s solar value chain.[7]

With these investments, Japanese enterprises are strengthening their foothold in Vietnam’s solar cell manufacturing market. As the demand for solar energy grows, Japan’s expertise and capital are likely to drive further expansion, positioning Vietnam as a key player in the global solar supply chain.

Challenges and Opportunities in The Solar Cell Manufacturing Market

Vietnam’s commitment to expanding its solar energy sector presents significant opportunities for the growth of its solar panel manufacturing market. The country has set ambitious renewable energy targets under its national energy development plans, encouraging both domestic and foreign investment in solar power projects. Government incentives, such as feed-in tariffs and tax benefits, have further stimulated the market, making Vietnam an attractive destination for solar panel production. Additionally, Vietnam’s geographic location and high solar radiation levels provide an ideal environment for large-scale solar energy adoption, ensuring a steady demand for locally manufactured solar components

However, despite these promising opportunities, challenges remain. The competition in Vietnam’s solar manufacturing market is intensifying, particularly with the strong presence of Chinese enterprises, which dominate global solar panel production. These firms bring economies of scale and cost advantages, making it difficult for other manufacturers to compete in price. Additionally, the supply chain for raw materials and components remains vulnerable to fluctuations in global markets, creating potential risks for production stability.

Conclusion

Vietnam’s solar cell manufacturing market is poised for significant growth, fueled by substantial investments from Japanese enterprises. The entry of companies like Vietnam Sunergy marks a pivotal step in establishing Vietnam as a competitive player in the global solar industry. With supportive government policies, technological advancements, and a favorable investment climate, Vietnam is well-positioned to capitalize on the growing demand for renewable energy solutions.

As the market evolves, stakeholders must address challenges such as competition, supply chain vulnerabilities, and regulatory complexities. However, the opportunities presented by the global transition to renewable energy far outweigh these challenges. With continued investment and innovation, Vietnam can emerge as a leader in the solar energy sector, contributing to a more sustainable future both domestically and globally.
