SpaceX has signed a major supply contract with Germany's SINGULUS TECHNOLOGIES to manufacture advanced, high-efficiency solar cells for its new Starmind satellites, the company announced Tuesday. Production will happen at SpaceX's Gigasat facility in Bastrop, Texas, with the first turnkey production line scheduled to arrive in the first half of 2027. The deal is sized to scale toward more than 100 GW of manufacturing equipment — an unusually large ceiling that signals how aggressively SpaceX intends to ramp its orbital AI data center constellation.
What SpaceX Announced
In a short statement posted to X, SpaceX framed the SINGULUS agreement as the foundation for "a durable option for advanced solar cell manufacturing" as it accelerates Starmind production in Bastrop. The language matters: this isn't a one-off cell purchase, it's a commitment to build out a vertically-integrated cell line on American soil, using SINGULUS turnkey equipment for heterojunction (HJT) cell production.
According to Deutsche Börse and MarketScreener disclosures tied to SINGULUS, the initial production line order under this supply contract is valued at over €60 million. That figure represents just the first line — the 100 GW equipment target referenced by SpaceX implies a dramatically larger multi-line buildout over the coming years, assuming the Starmind constellation hits deployment targets.
Why Heterojunction Cells, and Why Now
Heterojunction solar cells combine crystalline silicon with thin-film amorphous silicon layers to deliver higher conversion efficiencies and better temperature performance than conventional cells — characteristics that matter enormously in low-Earth orbit, where every watt of generation reduces how many square meters of panel each satellite needs to unfurl. SpaceX's Starmind "AI1" satellite design, unveiled in August 2026, already calls for 75-meter solar arrays and 30-meter radiative cooling panels to feed a peak compute budget of 250 kilowatts per spacecraft. Those are aircraft-carrier-scale appendages; higher-efficiency cells are the only way to keep the mass and deployment complexity tractable at scale.
SINGULUS, for its part, has been positioning itself as a turnkey HJT equipment vendor for several years. The strategic relationship with SpaceX didn't appear from nowhere — according to SINGULUS investor disclosures referenced by Deutsche Börse, SpaceX provided significant funding to the German firm in March 2026, with additional funding following in October 2026. Today's supply contract is the operational deliverable of that funding relationship.

How the Starmind Pieces Fit Together
To understand why SpaceX is willing to stand up a dedicated solar cell fab, you have to zoom out to the full Starmind thesis. The company announced the program in August 2026 as an orbital AI data center constellation — effectively putting GPU compute in space, powered directly by sunlight and cooled by radiating heat into the vacuum. The first-generation "AI1" satellite will carry NVIDIA's next-generation Rubin GPU and Vera CPU, with prototype launches targeted for early 2027 and broader production by late 2027, according to SpaceX's August briefing.
The constellation ambition is staggering: an FCC application filed by SpaceX, referenced across reporting by Teslarati and Tesla North, seeks authorization for up to one million satellites in sun-synchronous orbit. Each satellite could mass up to 4,000 kg. Even accounting for Starship's lift capacity, that's a decade-plus deployment campaign that will consume enormous quantities of solar cells, structural composites, and compute silicon.
Mike Nicolls, SpaceX's Senior Vice President of Starlink, summarized the logic in today's announcement: "Partnering with SINGULUS gives us a high-performance manufacturing path for solar cells for our Starmind satellites at our production facility in Texas." The operative words are "manufacturing path" — SpaceX isn't buying finished cells, it's buying the equipment to make them itself.
How We Got Here
The Bastrop site has been quietly expanding for well over a year. Originally built around Starlink gateway and user terminal production, the facility — now referred to as Gigasat in SINGULUS and investor materials — is being retooled as the center of gravity for SpaceX's satellite manufacturing. SINGULUS funding disclosures from March and October 2026 pointed to exactly this outcome without naming the specific product line; today's announcement closes that loop.
The 100 GW framing deserves careful reading. SpaceX isn't claiming it will install 100 GW of solar generation — that would be larger than the entire U.S. utility-scale solar fleet. The figure refers to the ceiling of manufacturing equipment capacity the partnership is designed to support. Interpret it as a planning envelope rather than a committed order book.
What to Watch Next
- H1 2027 line delivery. First SINGULUS production line installation and commissioning at Bastrop. Watch for building permits and equipment freight indicators.
- Early 2027 AI1 prototype launches. SpaceX has targeted early 2027 for the first Starmind prototypes. Those launches will use test cells, not the Bastrop-built product, but they'll validate the broader architecture.
- FCC action on the one-million-satellite filing. Regulatory outcome will determine whether the 100 GW equipment ceiling is aspirational or operational.
- Follow-on SINGULUS orders. If the first line performs, expect multi-line orders disclosed through SINGULUS investor filings well before SpaceX formally announces them.
Editor's View
What makes this deal notable isn't the dollar figure — €60 million is a rounding error in SpaceX capex terms. It's the signal that SpaceX is now willing to vertically integrate upstream into semiconductor-adjacent manufacturing to de-risk Starmind supply chains. That's the same playbook Tesla ran with 4680 cells and that SpaceX ran with Raptor engines: when the volume ambition is high enough and the merchant market can't be trusted to deliver, build the factory yourself. The 100 GW envelope tells you how big SpaceX thinks Starmind can become if the physics and economics hold up in orbit.
