Singulus Signs €60 Million+ SpaceX Contract for Heterojunction Solar Cells to Power Starmind Satellites

German equipment maker SINGULUS TECHNOLOGIES has signed a supply contract with SpaceX to deliver a turnkey production line for heterojunction (HJT) solar cells, with the order for the first line valued at more than €60 million, according to a company statement. The deal is tied to SpaceX's Starmind satellite program and is described by Singulus as the first step in a larger strategic partnership under which production is planned to scale to support more than 100 GW of production equipment.

Deal Terms and Delivery Timeline

According to Singulus, the contract covers a complete production line for manufacturing heterojunction solar cells, and the order volume for this first line exceeds €60 million. The German firm said the line is scheduled for delivery in the first half of 2027. Financial outlet TradingKey reported the same order value and delivery window, citing the Singulus announcement.

Singulus said this agreement is part of a broader strategic partnership under which it is planning to deliver multiple additional production lines to SpaceX. TradingKey reported the same framing, stating that Singulus plans to subsequently supply multiple production lines to SpaceX and to develop high-performance solar cells and related manufacturing equipment. A social media post from the account AGTP on X, which described the deal as covering a turnkey HJT line for SpaceX's Starmind satellite factory in Bastrop, Texas, likewise characterized the current contract as the first of multiple lines planned under the partnership rather than a single standalone order.

What the Solar Cells Will Power

Per the Singulus announcement, SpaceX intends to use the heterojunction cells to manufacture solar power systems for Starmind satellites at its Texas production facility. The company quoted a statement attributed to SpaceX in its release: "Partnering with SINGULUS gives us a high-performance manufacturing path for solar cells for our Starmind satellites at our production facility in Texas," according to Singulus's corporate release.

TradingKey reported that the procurement is primarily intended to support SpaceX's Starmind orbital AI computing project, under which the company is expanding AI satellite production capacity in Bastrop, Texas, with plans to use orbital solar energy to power onboard AI computing equipment and transmit data via a laser communications network, according to TradingKey's reporting.

Separately, retailer-focused outlet Basenor reported that Elon Musk stated on X that SpaceX had ordered 100 GW per year of HJT solar manufacturing equipment from Singulus for Starmind, adding that the push was "to create a sentient sun." TradingKey separately reported that Musk said on X that SpaceX had ordered HJT solar cell manufacturing equipment with an annual capacity of 100 GW from Singulus. Basenor additionally reported that Starmind's "AI1" satellite design, unveiled in August 2026, calls for 75-meter solar arrays and 30-meter radiative cooling panels to support a peak compute budget of 250 kilowatts per spacecraft, and that an FCC filing referenced in reporting by Teslarati and Tesla North seeks authorization for up to one million satellites in sun-synchronous orbit. These figures describe SpaceX's stated satellite design and licensing plans rather than confirmed production output.

Broader Partnership and Scale

Singulus said in its release that production is planned to scale to support more than 100 GW of equipment as SpaceX expands satellite manufacturing in Bastrop, Texas. TradingKey reported the same scale figure, attributing it to the Singulus announcement. Singulus also disclosed that its strategic relationship with SpaceX began in March 2026, and that SpaceX provided funding to Singulus in both March and October 2026, including a subordinated secured loan referenced in the company's statement.

Market Reaction and Materiality to Singulus

The announcement triggered a sharp move in Singulus shares. TradingKey reported that shares surged nearly 90% intraday on Germany's Xetra exchange on November 11, touching a high of €24, up about 89% from the previous session's close. Separately, Ukrainian outlet UNN, citing German tabloid Bild, reported that Singulus shares rose approximately 65% following the order announcement, temporarily increasing the company's market value by approximately €73 million. The two figures are not directly comparable: TradingKey cites an intraday high, while UNN cites a move reported on the day of its article, and our reading is that the gap reflects different measurement points in a volatile session rather than a factual conflict between the outlets.

UNN's report also framed the scale of the deal against Singulus's recent financial history, noting that the contract's value exceeds the company's entire 2025 revenue of €48.3 million. mlq.ai separately reported that Singulus posted revenue of €60.4 million for the first nine months of 2026, up about 36% year-on-year, with order intake of €60.3 million over the same period, and that the company expects full-year 2026 revenue of about €83 million.

Using those figures, the first SpaceX line alone, at more than €60 million, is worth roughly 72% of Singulus's own guided full-year 2026 revenue of €83 million (60 ÷ 83 ≈ 0.72), a comparison we calculate directly from the disclosed figures. The order is also comparable in size to the company's entire reported nine-month 2026 order intake of €60.3 million, underscoring how concentrated this contract is relative to Singulus's recent business activity. These are structural comparisons based on reported figures, not a judgment on future results, and the additional lines referenced in the broader partnership have not been separately valued in the available disclosures.

Bottom Line

Singulus has secured a contract worth more than €60 million for the first of what it describes as multiple planned heterojunction solar cell production lines for SpaceX's Starmind satellite program, with delivery targeted for the first half of 2027. The companies' relationship dates to at least March 2026 and includes prior SpaceX funding to Singulus. Based on the disclosed figures, this single order is large relative to Singulus's recent revenue and order intake, and the shares reacted accordingly, though the ultimate scale and value of the broader multi-line partnership has not yet been quantified in available reporting.
