On March 22, 2026, Musk officially unveiled SpaceX’s space AI computing-power satellites at the SpaceX event at the Terafab superchip factory. It is reported that a single mini-version satellite has a power as high as 100kW, and its solar panels can be unfolded to nearly 170 meters, supporting about 100 NVIDIA H200 units running at full load. According to Musk’s long-term plans, in the future, 1 million space AI computing-power satellites will be deployed, with power moving into the megawatt range—this will trigger an exponential surge in demand for high-power, lightweight, anti-radiation photovoltaic components.

According to media reports, a single space AI computing-power satellite has a power of 100kW, which is 10 times that of the Starlink V2 mini and 3.5 times that of the traditional communication satellite Jupiter 3. Networking one million units implies space-installed capacity at the百GW level. Due to the high cost and limited production capacity of traditional gallium arsenide batteries, they cannot support large-scale deployment; therefore, p-type HJT is expected to become the optimal solution in the mid-to-short term.

At present, China’s HJT batteries have already achieved mass production at an ultrathin thickness of 50–70μm. They significantly reduce weight, have excellent anti-radiation performance, and their cost is only about 1/10 of that of traditional space batteries, making them perfectly suited for large-scale LEO networking.

Previously, SpaceX has clearly indicated a preference for the P-type HJT route, while China holds a global edge in HJT production-line equipment, ultrathin silicon wafers, high-efficiency batteries, and space-grade encapsulation materials, and is capable of rapidly expanding production and ensuring stable delivery.

Industry insiders point out that with SpaceX and other global low-orbit constellations launching dense batches, demand for HJT equipment, ultrathin silicon wafers, anti-radiation encapsulation films, CPI flexible packaging, and more is surging. There has already been the rollout of billion-yuan-level equipment procurement intention, and orders across the industrial chain are continuously being released. With SpaceX rolling out at scale, China’s high-efficiency battery + ultrathin silicon wafer + space materials system has become a global benchmark in space photovoltaics, seizing the leading position in future space energy.
