Company Description
Solestial exists to deliver abundant energy in space. Our breakthrough technology is a silicon solar cell engineered for space to self-cure radiation damage under sunlight at operating temperatures as low as 65°C. Solestial solar cells are packaged in an ultrathin, low-mass, flexible solar power module designed to withstand up to 10 years in a variety of destinations in space. Our flexible solar power modules can be produced on automated machines resulting in costs 90% lower than traditional III-V multijunction solar products.
In 2025, Solestial will produce silicon photovoltaics for space at a run rate of 1 MW, a scale comparable to the annual global capacity of all III-V solar manufacturers combined. From today’s satellite constellations and research projects to tomorrow’s lunar settlements and services in space, Solestial’s innovative technology represents a paradigm shift for space solar; an affordable, scalable solution to power sustained development. Solestial is a US company manufacturing solar cells and flexible solar power modules in Tempe, Arizona. Investors include space industry leaders including AE Industrial Partners and Airbus Ventures.
