Solar Firm Starts Second U.S. Module Phase
Taiwan-based 碩禾 began mass production of a second U.S. solar module phase adding one gigawatt of annual capacity.
Updated on Nov. 6, 2026 in Manufacturing
Taiwan-based solar firm 碩禾 began mass production in October on the second phase of its U.S. solar module operations, adding one gigawatt of annual module capacity. Its first U.S. phase, a 500-megawatt line, is running at full capacity.
Why it matters
The expansion shows Taiwanese solar makers building U.S.-based manufacturing rather than relying solely on overseas production. Separately, 聯合再生 and 中美晶 plan a U.S. module plant with the same one-gigawatt annual capacity, expected to start production in 2027.
碩禾's second U.S. phase adds one gigawatt of annual module capacity, following a 500-megawatt first line that is operating at full capacity. The source does not report output volumes, sales figures or the share of production sold in the United States.
The players
碩禾
碩禾 is a Taiwan-based solar firm that has expanded module manufacturing into the United States.
聯合再生
聯合再生 is a Taiwan-based solar company planning a U.S. module plant with 中美晶.
中美晶
中美晶 is a Taiwan-based semiconductor and solar materials company partnering with 聯合再生 on a U.S. plant.
The details
碩禾 acquired U.S. solar module production equipment in 2025 and began manufacturing U.S. modules that year, with TOPCon and PERC models in its lineup. The company began mass production on its second U.S. phase in October.
Timeline
July: 聯合再生 announced plans with 中美晶 for a U.S. solar module plant.
2025: 碩禾 acquired equipment and began U.S. module manufacturing.
October: 碩禾 began mass production on its second U.S. phase.
2027: The 聯合再生 and 中美晶 plant is expected to begin production.
Market Landscape
Taiwanese solar makers are building U.S. module lines of their own, as 碩禾 extends its U.S. operations and 聯合再生 plans a parallel plant. 元晶, by contrast, keeps prioritizing Taiwan production and earns about 10% of revenue overseas, mainly from Japan.
For buyers and installers, the added U.S. module capacity could support domestic supply for rooftop, ground-mounted and data-center solar projects. The stub does not indicate changes to pricing or product availability for consumers.
The takeaway
Domestic module capacity from Taiwanese manufacturers is growing, and watching whether planned 2027 production begins on schedule will show how quickly that supply expands. Readers tracking solar costs can follow module output announcements from these firms.
