Tokyo-based solar manufacturer VSUN has initiated commercial production at its 4GW silicon wafer plant in Vietnam, marking a significant milestone. Construction began in November, and production of the first n-type 182.2×182.2mm silicon wafer is underway, symbolizing the plant’s operational start.
The company anticipates achieving a full production capacity of 4GW annually by the end of April. This endeavor aligns with VSUN’s objective of establishing a vertically integrated solar supply chain. Notably, its solar cell subsidiary, TOYO Solar, recently secured a crucial long-term polysilicon supply agreement with South Korean-owned OCI, ensuring a stable supply chain.

VSUN’s Phase I plan includes the current operational capacity of the wafer plant, with Phase II already in progress, focusing on expanding cell capacity. Dr. Aihua Wang, VSUN’s chief technology officer, discussed the technological shift from p-type to n-type cells and disclosed the company’s strategic moves in the US market. VSUN plans to introduce 2GW of annual nameplate capacity for solar cells and modules during the fourth quarter of 2024 and 2025, respectively.
VSUN’s venture into commercial production in Vietnam underscores its commitment to advancing solar technology and strengthening its global presence. With plans for expansion and strategic partnerships in place, the company aims to solidify its position in the renewable energy sector while driving innovation and sustainability forward.
