Solestial

Solestial exists to deliver abundant energy in space. Its core product is a flexible solar power module. Each module is comprised of Solestial's breakthrough technology, a silicon solar cell engineered for space to self-cure radiation damage under sunlight at temperatures as low as 65°C. Solestial flexible solar power modules are ultrathin, low mass, and radiation hardened. Affordability and scalability are the key differentiators of Solestial modules. Its components are more affordable to source than III-V multijunction solar panel components and can be quickly manufactured on automated machines. Terrestrial silicon solar panels are affordable but degrade rapidly in space due to radiation and other factors. Solestial flexible solar power modules anneal radiation damage at normal operating temperatures allowing them withstand up to 10 years in a variety of destinations in space. Solestial’s innovative solar products provide customers with the best combination of radiation hardness, performance, and cost, at virtually unlimited scale. Solestial's innovative technology represents a paradigm shift for space solar; an affordable, durable, scalable solution to power development in space. Solestial is a US company manufacturing in Tempe, Arizona.
