Recently, TOYO, a Japanese photovoltaic manufacturer, announced plans to expand the capacity of 1.5g W heterojunction batteries in Houston , Texas, USA.

The company said that the investment amount of the expansion project is 357 million US dollars (about 2.417.6 billion RMB, exchange rate 1 US dollar = 6.772 RMB), which is carried out in stages, and the whole project is expected to be completed and put into preliminary trial production within 20 months.
According to the tracking of digital new energy DataBM. Com, TOYO has been building battery capacity in the United States for a long time. In September
2024, TOYO announced plans to build a 2G W component manufacturing facility in the United States. At that time, the company said it expected to produce batteries in the United States in the first half of 2026. In November
2024, the company acquired 100% of the Solar Plus Technology Texas LLC in the Houston metropolitan area. At that time, it was reported that the new factory acquired by TOYO covers an area of 52689. 03 square meters, and it plans to build 2.5g W solar module manufacturing capacity , expanding to 6.5g W by 2029 . In October 2025, TOYO Houston Component Plant was put into operation.
Just one month before TOYO announced its Houston module plant, in October 2024, the company announced the construction of a 2G W photovoltaic cell plant in Ethiopia . The aim is to provide tariff-free photovoltaic cells for its module factories in the United States.
However, in May this year, several photovoltaic module manufacturers in the United States applied to investigate photovoltaic products from Ethiopia. According to
the allegations, two Japanese companies, TOYO and Origin Solar, produce silicon wafers for solar cells in Ethiopia from China . The two companies assembled solar cells into photovoltaic modules in Ethiopia or Vietnam and eventually exported them to the United States to avoid import tariffs.
TOYO denied the allegations in an interview with the media.
