Huang Ren-Hsuan Discusses the "Final Frontier"! Space Photovoltaic Concept Stocks Roundup

On Tuesday, March 17th, the photovoltaic equipment sector performed strongly, with Huamin Co. rising over 10%, Guosheng Technology, GCL System Integration, and others hitting the daily limit. Yicheng New Energy, Shichuang Energy, Zerun New Energy, Foster, and others also followed with strong gains.

In terms of news, on March 16th, U.S. time, NVIDIA held its GTC annual developer conference in San Jose, California, launching the “Space Computing” platform, which includes the Space-1 Vera Rubin module, IGX Thor, and Jetson Orin. NVIDIA CEO Jensen Huang emphasized: “Space computing, the ultimate frontier, has arrived. As satellite constellations are deployed and deep space exploration advances, intelligence must exist where data is generated.”

Powerful satellites are expected to push satellite single-star power consumption to a new level. According to Guojin Securities research reports, a single NVIDIA GB300 chip consumes 1.4kW, and a typical 8-card cabinet system consumes up to 14kW. Architectures like Blackwell and Rubin, based on NVL72 and NVL144, have power levels of 132kW and 240kW respectively. The power of a single satellite in a power satellite system may far exceed traditional satellites.

Guojin Securities states that regarding single-star power, considering that the theoretical calculation shows SpaceX V3 satellites reaching 57-76kW per satellite, China is also actively developing ultra-high power systems in the 50-100kW range. Assuming that between 2026 and 2028, the average power of satellites worldwide increases proportionally with the expansion of solar wing area by 50%, the installed capacity of space photovoltaics is expected to be 413MW in 2026, 1,426MW in 2027, and 4,277MW in 2028.

A research report from China Post Securities at the end of February indicated that space photovoltaics have growth potential. Technological iteration brings new opportunities: the evolution of GaAs-HJT-perovskite stacking.

GaAs remains the mainstream technology route, with high reliability but high costs.

HJT relies on the mature crystalline silicon industry, significantly reducing costs compared to GaAs, and heterojunctions serve as the foundation for developing perovskite stacking solutions. Short- to medium-term growth prospects are promising.

Perovskite stacking is still in the early research stage, facing issues such as insufficient stability under sunlight or high temperatures and short lifespan, which need breakthroughs. As technology matures, capacity increases, and costs decrease, medium- to long-term growth potential is expected.
