Singulus Technologies has signed a contract with SpaceX for a turnkey HJT solar cell production line, with delivery scheduled for the first half of 2027. The Germany-based company said the contract is part of a strategic partnership under which it plans to deliver multiple additional lines.

Singulus said production will scale to support more than 100 GW of production equipment as SpaceX accelerates satellite manufacturing in Bastrop, Texas. It did not say whether the figure refers to annual or cumulative capacity, or how many lines that would involve.

Under the partnership, Singulus will develop both high-performance solar cells and the production equipment to make them, based on technologies already deployed at scale. Mike Nicolls, SpaceX’s senior vice president of Starlink, said the partnership gives SpaceX a high-performance manufacturing path for solar cells for its Starmind satellites at the Texas facility.

Lars Lieberwirth, a member of Singulus’ executive board, said the company’s platform combines wet chemistry, vacuum coating, and thermal processing, and that the partnership would allow it to industrialize those capabilities at scale and strengthen its position as a leading Western supplier of next-generation solar cell technology.

The two companies entered the partnership in March 2026. SpaceX provided significant funding to Singulus that month and again in October as part of a subordinated secured loan, Singulus said, without disclosing the amounts.

SpaceX CEO Elon Musk said in January that SpaceX and Tesla were each working to build 100 GW a year of solar manufacturing capacity in the United States, a target that would far exceed current US production, and has tied the push to solar-powered computing in space. Other manufacturers are also adding HJT cell capacity in Texas, including Toyo’s planned 1.5 GW factory and SEG Solar’s planned 4 GW plant near Houston.
