Solestial Secures $17M Series A to Power a Revolutionary Leap in Space Solar Energy

Solestial, Inc., the solar energy company for space, is excited to announce that it has successfully raised $17,000,000 in funding, marking a significant milestone in its mission to revolutionize the space solar industry. Headquartered in Tempe, Arizona, Solestial has rapidly emerged as a leader in creating innovative solar solutions specifically engineered for space. The company’s breakthrough technology is centered on a silicon solar cell that can self-cure radiation damage under sunlight—even at temperatures as low as 65°C. Packaged within a flexible solar power module designed to last up to 10 years in a variety of harsh space environments, Solestial’s technology not only delivers high efficiency but also cuts production costs by up to 90% compared to traditional III-V solar products, thanks to its automated manufacturing process. This infusion of capital comes at a pivotal time when the industry faces an unprecedented demand for 100 MW of solar power in space over the next five years. Current products in the market are prohibitively expensive and slow to manufacture, with estimates exceeding $60 billion and taking more than a decade to fully deploy. Solestial is effectively addressing this gap by offering a space-optimized silicon solution that promises both cost efficiency and rapid scalability. The new funds will accelerate research and development, enhance production capabilities, and enable strategic partnerships to further disrupt and reshape the market landscape. As Solestial takes this giant leap forward, it invites investors, partners, and the wider industry to join in its journey to unlock a future where affordable, durable, and scalable solar power powers the next era of space exploration and development.
