Date: January 28, 2026
Sector: Power Equipment / Commercial Aerospace
Rating: Overweight (Maintained)
Executive Summary
The convergence of commercial aerospace acceleration and the imminent deployment of space-based computing is creating a structural inflection point for space-based photovoltaics (PV). With SpaceX targeting a 100x reduction in launch costs through Starship’s full reusability and Tesla/SpaceX planning 100GW annual capacity each, the economic viability of massive satellite constellations is shifting from theoretical to operational. Concurrently, China is aggressively accelerating its low-earth orbit (LEO) infrastructure, with record-breaking frequency orbit applications and concrete deployment timelines for the "Guowang" and "Qianfan" constellations.
In this high-growth environment, power supply remains the critical bottleneck and primary value driver for satellites. Perovskite solar cells, characterized by superior specific power (power-to-weight ratio) and flexibility, are emerging as the technology of choice, moving rapidly from laboratory validation to orbital demonstration. We maintain an Overweight rating on the sector, highlighting that space PV is poised for non-linear growth driven by both overseas capacity expansion and domestic industrialization. Investors should focus on companies with established technical moats in perovskite/HJT technologies, CPI film materials, and those integrated into the global supply chain.
Key Takeaways
1. Global Launch Capacity & Cost Dynamics: A Non-Linear Growth Trajectory
The fundamental economics of space infrastructure are being rewritten by advancements in launch vehicle technology.
* SpaceX Catalysts: Elon Musk has outlined aggressive targets: Tesla and SpaceX each plan to build 100GW of annual capacity within three years. Crucially, the Starship program aims for full reusability within the year, potentially reducing space access costs by a factor of 100.
* Volume Explosion: With a target launch frequency of >1 per hour and an ultimate goal of producing 10,000 Starships annually, the near-Earth orbit lift capacity could reach 1 million tons/year. Assuming an average satellite weight of 1 ton, this implies a potential launch volume of 1 million satellites annually within three years—a stark contrast to the current ~3,000/year baseline. This represents a non-linear expansion in addressable market size.
* Space Computing Reality: Musk predicts that scalable space-based computing will become a reality within 2-3 years, further intensifying the demand for reliable, high-efficiency onboard power systems.
2. China’s Strategic Acceleration: Policy Meets Execution
China is transitioning from strategic planning to tangible execution in the LEO sector, driven by high-level state support.
* Frequency Orbit Dominance: China recently submitted applications for 203,000 satellite frequency orbits to the International Telecommunication Union (ITU), setting a new record for single-batch declarations. This secures critical strategic resources for future deployments.
* Constellation Timelines:
* China SatNet (Guowang): Plans to deploy 13,000 LEO satellites between 2026 and 2030. Internal bidding processes are reportedly initiating.
* Qianfan Constellation: Targets over 10,000 LEO satellites by 2030.
* Aggregate Demand: Combined, these two major constellations imply an average annual launch rate of nearly 3,000 satellites from 2026 to 2037.
* Computing Infrastructure: Projects like "Xingsuan" and "Chenguang" are establishing the framework for space-based computing. The "Chenguang-1" satellite is expected to launch in early 2026, marking a significant milestone in industrialization.
3. Technology Shift: Perovskite Ascendancy
Traditional silicon-based solutions are facing competition from next-generation materials better suited for the harsh constraints of space (weight, flexibility, radiation resistance).
* Perovskite Advantages: The high specific power (W/kg) and flexibility of perovskite modules make them ideal for satellite applications where every gram counts.
* Commercial Validation:
* Singfilm Solar: Has successfully delivered the first batch of flexible, ultra-thin perovskite modules in January 2026. These are scheduled to launch aboard a SpaceX Falcon rocket in Q4 2026.
* Shanghai Gangwan: Has already conducted in-orbit verification for four satellite perovskite units since 2023.
* Industry Adoption: Leading manufacturers globally are increasingly integrating perovskite technology, signaling a shift from R&D to commercial penetration.
4. Investment Themes & Beneficiaries
We identify three primary investment vectors within the space PV value chain:
| Investment Theme | Core Logic | Key Companies to Watch |
|---|---|---|
| Space Power Supply Leaders | Direct beneficiaries of satellite power system demand; leaders in Perovskite, HJT, and GaAs technologies. | Junda Shares (Perovskite+CPI partnership), Mingyang Smart Energy (Perovskite/HJT/GaAs), Shanghai Gangwan (Space qualification), Trina Solar, Jinko Solar |
| Equipment & Overseas Capacity | Benefiting from the T+X factory audit cycle and global capacity expansion (100GW plans). | Maxwell Technologies (Maiwei), Autowell, Liancheng CNC, Jiejia Weichuang, Shuangliang Eco-Energy |

Risks / Headwinds
While the growth trajectory is compelling, investors must monitor the following risks:
- Policy and Regulatory Uncertainty: Changes in international space regulations, ITU frequency allocation disputes, or shifts in domestic subsidy/support policies could delay deployment timelines.
- Commercial Aerospace Execution Risk: The projected non-linear growth relies heavily on the successful mass production and full reusability of next-gen launch vehicles (e.g., Starship). Any significant technical setbacks or delays in achieving cost reductions will dampen the economic case for massive constellations.
- Technology Performance Risks: Perovskite technology, while promising, still faces challenges regarding long-term stability and efficiency in the extreme space environment (radiation, thermal cycling). If in-orbit performance (efficiency decay, lifespan) falls short of expectations, adoption rates may slow.
- Supply Chain Bottlenecks: Rapid scaling of satellite production may strain the supply of specialized materials (e.g., CPI films, specialized pastes), leading to cost inflation or delivery delays.
Rating / Sector Outlook
Rating: Overweight (Maintained)
We believe the space PV sector is transitioning from a niche experimental market to a core component of the global digital infrastructure. The alignment of launch cost deflation (via reusable rockets) and demand inflation (via space computing and broadband constellations) creates a rare dual-engine growth scenario.
The sector outlook remains highly positive for the 2026–2030 period. The immediate catalysts are the commencement of large-scale bidding for Chinese constellations and the orbital validation of perovskite technologies by key players like Singfilm and Shanghai Gangwan. We expect the market to re-rate companies that can demonstrate verified space-grade qualifications and secure positions in the global supply chain.
Investment View
The narrative for space-based photovoltaics has shifted from "conceptual potential" to "industrial inevitability." For institutional investors, the key is to differentiate between pure concept stocks and companies with tangible technological moats and supply chain integration.
Strategic Recommendations:
- Prioritize Technology Leaders with Space Qualifications: Focus on companies like Junda Shares and Shanghai Gangwan, which have moved beyond R&D to actual delivery and in-orbit verification. Their early mover advantage in perovskite application provides a defensive moat against late entrants.
- Monitor the "T+X" Supply Chain Cycle: As overseas giants (Tesla/SpaceX) ramp up capacity, equipment manufacturers (Maxwell, Autowell) and material suppliers (DKEM, First Applied Material) that pass rigorous international audits will see sustained revenue visibility. The "T+X" model (where T is the technology provider and X is the manufacturer) suggests a deepening integration of Chinese supply chains into global aerospace projects.
- Diversify Across the Value Chain: While module makers capture headlines, the real margin resilience may lie in specialized materials (CPI films, conductive pastes) and precision equipment. Companies like Mingyang Smart Energy offer a diversified play across multiple tech paths (Perovskite, HJT, GaAs), reducing single-technology risk.
Conclusion:
The era of "Space Internet" and "Space Computing" is arriving faster than anticipated, underpinned by a revolution in launch economics. Space PV is not merely a subsidiary segment but the essential enabler of this new orbital economy. We advise investors to accumulate positions in high-certainty beneficiaries of this structural shift, particularly those leading the perovskite revolution and those embedded in the expanding global launch supply chain.
