SpaceX announced November 10 it has ordered solar cell manufacturing equipment from German supplier Singulus Technologies. The equipment has 100 gigawatt annual production capacity for heterojunction solar cells to support the Starmind artificial intelligence satellite program. Elon Musk stated on social platform X the purchase aims to create what he calls a 'sentient sun.' An official November 10 press release from Singulus confirmed the supply contract for complete heterojunction solar cell production lines to expand Starmind satellite manufacturing at SpaceX's Texas Bastrop facility.
Singulus to Deliver First Production Line in First Half 2027
Singulus stated the first production line is scheduled for delivery in the first half of 2027. The company plans to supply multiple production lines to gradually expand equipment scale supporting solar cell production equipment demand exceeding 100 GW.
Mike Nicolls, Senior Vice President of SpaceX's Starlink division, stated the collaboration with Singulus will establish high-performance solar cell manufacturing capability for the Texas Starmind satellite production base. He indicated Singulus's process expertise combined with SpaceX's long-term commitment provides a reliable pathway for expanding solar cell production volume.
Singulus specializes in thin-film coating, wet chemical processing, and thermal treatment equipment. The company stated the collaboration will develop high-performance solar cells and production equipment based on technology with proven scaled application experience.
SpaceX Established Strategic Partnership with Singulus in March 2026
Singulus noted this is not the first collaboration between the two parties. SpaceX established a strategic partnership with Singulus in March 2026 and provided substantial funding support in March and October, which are part of the recently announced subordinated secured loans.
Musk's reference to a 'sentient sun' currently remains a vision in his description of the Starmind program. Official announcements confirm solar cell manufacturing equipment procurement and satellite mass production support plans but do not explain how a sun with consciousness would be realized.
SpaceX's planned first-generation AI data center satellite Starmind AI1 features solar panels approximately 70 meters wide with an average computing load of 160 kilowatts, highlighting solar energy's importance in Musk's space AI strategy.
Musk Explains Space Solar Infrastructure Design for AI Data Centers
Musk stated in January at the World Economic Forum that using solar energy to build AI data centers in space is a choice that 'doesn't require much thought,' requiring only solar panels facing the sun and radiators facing away from the sun.
Musk further explained on the evening of November 2 when responding to Sequoia Capital partner Shaun Maguire on social platform X that aluminum radiators facing away from the sun primarily face cosmic background radiation at temperatures only about 3 degrees above absolute zero, making cooling capacity of approximately 1,300 watts per square meter not difficult to achieve.
He estimated solar panels can generate approximately 250 watts of power per square meter, meaning the satellite's required solar panel area is approximately five times that of the radiators, with most of the satellite's weight coming from the solar panels.
