Singulus to supply HJT solar cell line to SpaceX
Singulus Technologies has signed a contract to supply SpaceX with a turnkey production line for heterojunction (HJT) solar cells. The German equipment maker expects to deliver more lines under the two companies’ partnership.
The first line is due for delivery in the first half of 2027, according to a press release from Singulus. SpaceX will use the cells in satellites built at its production facility in Bastrop, Texas. The contract value has not been disclosed.
The partnership began in March 2026. Under it, Singulus will develop both the solar cells and the equipment used to make them, building on technologies already deployed at scale. As SpaceX accelerates satellite manufacturing, production is to scale “to support more than 100 GW of production equipment”, Singulus says.
Lars Lieberwirth, member of Singulus’s executive board, points to the company’s platform, which combines wet chemistry, vacuum coating and thermal processing in one place, as what sets it apart.
“The strategic partnership with SpaceX allows us to further industrialize these capabilities at a meaningful scale and solidify our position as a leading Western provider of next-generation solar cell technology,” he says.
For SpaceX, the deal secures a manufacturing route for solar cells at its own facility. Mike Nicolls, SpaceX’s senior vice president of Starlink, describes it as a “durable option for scaling solar production”.
“Partnering with Singulus gives us a high-performance manufacturing path for solar cells for our Starmind satellites at our production facility in Texas,” he says.
SpaceX also supports Singulus financially. It provided significant funding in March 2026, and more in October as part of a recently announced subordinated secured loan.
