On November 10, 2026, SINGULUS TECHNOLOGIES, a German maker of solar cell manufacturing equipment, announced that it had signed a contract with SpaceX to supply one turnkey production line for heterojunction (HJT) solar cells. The company also refers to plans to deliver multiple additional lines and to a large-scale production concept of "more than 100GW." At this point, however, the only contract that can be confirmed is the first line, scheduled for delivery in the first half of 2027. SpaceX also provided funding to SINGULUS in March and October 2026, so the deal has the unusual feature of SpaceX buying manufacturing equipment from a company it is supporting financially. To assess the announcement, it is necessary to separate confirmed orders from future plans and to understand the financial relationship between the two companies.
SpaceX has ordered one line; additional equipment is still at the planning stage
According to SINGULUS, the contract is part of a strategic partnership between the two companies, under which it will supply one HJT solar cell production line on a turnkey basis. A turnkey contract is one in which a full set of manufacturing equipment is installed and handed over to the customer ready to operate. The first line is scheduled for delivery in the first half of 2027. Mike Nicolls, SpaceX's Senior Vice President for Starlink, explained that it will be high-performance equipment for manufacturing solar cells for Starmind satellites at the company's production site in Texas. He also indicated that the long-term partnership could accommodate future expansion of production scale.
HJT is a solar cell technology that forms thin films on both sides of a crystalline silicon wafer, reducing charge recombination losses and raising power generation efficiency. Lars Lieberwirth, a member of the SINGULUS management board, cited as a company strength the ability to integrate wet-chemical processing, vacuum deposition, and thermal processing on a single manufacturing platform. The company hopes the partnership will strengthen its position as a leading supplier of next-generation solar cell technology in Western countries. According to the announcement, the two companies will also work on developing high-performance solar cells and the equipment to make them, building on existing mass-production technology. In other words, the collaboration extends beyond equipment supply to the design and development of the solar cells themselves.
The press release describing the strategic partnership does not state a contract value. However, in a separate release published the same day, November 10, SINGULUS disclosed that the order value for the first production line exceeds €60 million. That is more than about ¥10.6 billion in yen terms (converted at ¥176.5 per euro). None of the documents gives specific figures for how many GW of capacity each line represents, how many additional lines will be introduced, or when they will be delivered. The additional equipment is described only as "planned delivery of multiple lines," and those orders have not been finalized.
On March 27, 2026, SINGULUS also announced that it had won a first order worth tens of millions of euros from an unnamed technology partner. The strategic partnership with SpaceX began in the same month, but public information does not confirm whether that anonymous customer was SpaceX. The "more than 100GW" figure in the latest announcement should also be treated with caution. SINGULUS refers to scaling up to support production equipment of more than 100GW as SpaceX accelerates satellite manufacturing in Bastrop, Texas. But it is unclear whether the 100GW refers to annual production capacity, cumulative production scale, or how many production lines it would correspond to. It therefore cannot be interpreted to mean that SpaceX has already ordered 100GW worth of equipment.
SpaceX provided funding in March and October, then ordered a line in November
What characterizes this contract is the financial relationship between SpaceX and SINGULUS. The two companies entered into a strategic partnership in March 2026, and SpaceX provided SINGULUS with "significant funding." The announcement does not disclose the specific amount. SINGULUS then announced on October 21 that it had raised a subordinated, secured loan of about €22.75 million. A subordinated loan is financing in which the repayment priority is set lower than that of other ordinary debt, so the lender bears correspondingly higher credit risk. The announcement reveals that SpaceX also provided additional funds in October as part of this loan.
The loan of about €22.75 million is equivalent to about ¥4 billion, using the exchange rate published by the Bank of Japan as of 5 p.m. on November 6, 2026 (about ¥176.5 per euro). SINGULUS's 2026 revenue outlook, presented on May 12, was about €83 million, so the loan equals about 27% of that. The first production line, meanwhile, is worth more than €60 million, so the loan is less than 40% of the order value. The order for a single line alone is more than 70% of the company's expected annual revenue. However, it has not been disclosed when revenue from this order will be recognized, so it cannot be compared directly with the 2026 revenue outlook.
The October loan was used to repay in full the debt related to China's Triumph Science and Technology Group. That debt arose from past loans and customer advance payments for individual projects. The new loan replaced the debt owed to Triumph, and the roughly 16.75% stake in SINGULUS that Triumph held also moves to German investors. In other words, SINGULUS was already reviewing its funding sources and shareholder structure before the supply contract with SpaceX was announced.
Arranged in chronological order, the relationship runs as follows: in March 2026, SpaceX provided funding to SINGULUS and began the strategic partnership; in October, it contributed additional funds; and on November 10, the supply contract for one HJT solar cell production line was announced. For an equipment maker, winning a large order is of little use if it cannot secure the funds needed to build and deliver the equipment. When a customer lends money to the manufacturer, it can support the supplier's cash flow while advancing the procurement of the equipment it needs. SINGULUS had previously relied on loans and customer advance payments to carry out projects, so this deal can also be seen as combining financial support with equipment procurement.
However, confirmed facts need to be distinguished from speculation regarding the relationship between funding and the order. The announcements confirm that SpaceX is supporting SINGULUS financially and that it is purchasing manufacturing equipment from the company. It is not clear, however, whether the contract price was determined through competitive bidding, or whether the financing and the equipment purchase were agreed as an integrated condition. There is also no evidence to conclude that SpaceX intends to effectively lock in SINGULUS, for example by restricting supply to other companies.
Focus on delivery in the first half of 2027 and orders for additional lines
The contract can be seen as reflecting real demand behind SpaceX's expansion of solar cell production capacity. HJT is a technology with a track record in mass production, and SINGULUS has long made related manufacturing equipment. Meanwhile, the company's 2025 revenue was €48.3 million and its order backlog at the end of March 2026 was €69.5 million, so a large contract with SpaceX is significant relative to the size of its business. It is also reasonable from the standpoint of securing a stable equipment supply for an important customer to support its supplier's cash flow through loans. The plan to introduce multiple lines, and the long-term partnership that Mike Nicolls mentioned, also support the view that SpaceX is seeking to expand solar cell production capacity.
Still, the existence of real demand is a separate matter from whether every future plan has been fixed in contracts. What the announcement confirms is the first production line to be delivered in the first half of 2027 and the fact that SpaceX has provided funding to SINGULUS. For the multiple additional lines, delivery plans are indicated, but the number of contracts and the amounts have not been disclosed. To evaluate the future scale of the business, it will therefore be necessary to see whether additional contracts are actually signed.
SpaceX's planned solar cell factory in Bastrop has been reported to have a planned annual capacity of 10GW, based on a permit application filed with the county. This is a planned figure based on press reports, however, and it is unclear whether its scope and timeframe match the "more than 100GW" in the SINGULUS announcement. The two cannot be compared to calculate what share of future plans the current contract represents. To evaluate such capacity figures, the capacity per line and the stage of equipment introduction would need to be clarified.
The key point to watch is whether SINGULUS announces orders for additional lines before the end of June 2027, the delivery deadline for the first production line. If the number and value of additional contracts become clear, it would confirm that the expansion of production capacity, now only at the planning stage, has moved on to concrete orders. On the other hand, even if the first line is delivered on schedule, that would mean only that the existing contract has been fulfilled; it would not support the existence of orders for additional lines. If the capacity per line is disclosed, it would also provide a basis for estimating the scale of equipment needed for the "more than 100GW" concept.
The partnership between SpaceX and SINGULUS is drawing attention not only as an expansion of production capacity for satellite solar cells, but also as a move to put a manufacturing equipment supply system in place through customer financial support. At this point, however, what is confirmed is the first line worth more than €60 million, and whether large additional investments materialize depends on future contracts. Delivery status in the first half of 2027 and disclosure of orders for additional lines will be important indicators for judging progress on SpaceX's solar cell manufacturing plans.
