Solestial, Inc.

The future of space infrastructure runs on American innovation. Proud to source and manufacture in the USA as we deliver solar tech for the next generation of space missions. Happy Fourth of July from the Solestial team. #BuiltInAmerica #MadeInUSA #SpaceTechnology

We are happy to share that @YorkSpaceSystem (NYSE: YSS) has completed its acquisition of Solestial, securing a domestic source for critical space solar capability.   Solestial will continue to serve external customers as we scale. Full press release: bit.ly/3Ql4uEz

Solestial’s VP - Ops, Lisa Morris, was recently featured on @inherorbitpod where she shared her experience building and scaling Solestial’s manufacturing operations to meet growing space solar demand. Listen to the episode: bit.ly/49ktSRh

We are thrilled to announce that @YorkSpaceSystem has entered into a definitive agreement to acquire Solestial. Solestial will operate as a wholly owned subsidiary of York and continue to serve a broad range of external commercial and government customers. bit.ly/49BEISY

Solestial is growing. We’re looking for builders, problem solvers, and innovators to help us scale our next gen Si PV for space. Learn more: bit.ly/4nlI0zx 🚀 Facilities & Equip Tech 🚀 EHS Manager 🚀 Biz Dev Manager, Commercial 🚀 Process Tech (multiple openings)

Several companies offer Si PV for space. Solestial stands apart: ☀️ Manufacture our own solar cells ☀️ Cells self-heal radiation damage on orbit ☀️ Verified low-temperature annealing In 2023, @CEA_Officiel validated our annealing results. Learn more: prn.to/4upljww

Over the past year, Solestial has strengthened its leadership team to help scale our manufacturing and commercialization efforts. We welcomed CEO, Margo DeNaray, and added executives Nicolas Milgen - CFO, Lisa Morris - VP, Operations; and Danny Field - VP, Product & Programs.

This is what relentless iteration looks like. A trained Solestian looks at this picture and sees countless improvements made to our cells, modules, processes and tools. Our strong product is the result of our strong team.

Space Symposium is off to a strong start. We were thrilled to connect with our friends from the @USSpaceForce. Solestial’s Senior Director of Government Sales & Programs, Vince Hearn, is on site and looking forward to many more conversations this week.

Space Power Workshop is right around the corner! Meet with Danny Field, Solestial’s VP of Product and Programs: bit.ly/4sA9jb4 Discuss your mission requirements and learn how Solestial’s radiation-hardened silicon solar technology can help you achieve your goals.

Will we see you at Space Symposium? Schedule time with Vince Hearn, Solestial’s Senior Director of Government Sales & Programs: bit.ly/4sZTMRA Connect with Vince to learn how our radiation-hardened silicon solar technology for space is supporting mission readiness.

We're pleased to welcome Lisa Morris as VP of Operations. Lisa has extensive experience in advanced manufacturing and space. She joins us from Virgin Galactic, where she scaled the commercial spaceflight program. Since 2025, Lisa has served as an AZ Space Commissioner.

@RKLBMan Great to see our rad-hard Si solar cells included in your article! Solestial is the only solar technology that self-cures radiation damage at operating temperatures in space.

Space Data Centers are a big topic right now. I wanted to spend some time understanding Space Solar for my own DD. The tech, the companies involved, and the application layers. So - here's a new article (it's free) about Space Solar, including how $RKLB and $RDW fits in to the big picture. It gets a bit technical (beyond my capacity), so I tried my best to make it digestible + understandable. Let me know your thoughts! BTW - will be converting to an X article soon. open.substack.com/pub/rklbman/p/…

Solestial's latest customer delivery is two meters long, delivers 320W per panel, and features innovative string routing designed to minimize the generation of residual dipoles, even in the event of power failure. Like all our modules they self-heal radiation damage in space.

Our new solar manufacturing equipment, acquired from Meyer Burger Germany, demonstrates our commitment to scaling production of our proprietary Si solar technology, the only solution designed to self-heal radiation damage in space.

Orbital data centers have become one of the most talked-about topics in space. Making them a reality comes down to several technical challenges, including power, one of the industry’s longest-standing bottlenecks. (1/3)

Solestial delivers silicon solar engineered for space to anneal radiation damage, combining affordable material inputs, shorter lead times, and durability that terrestrial solar was never designed to achieve in orbit. (2/3)

Solestial is a cost-effective alternative to III-V solar that doesn’t compromise performance. For large-scale space infrastructure to move from concept to deployment, success will depend on power that can be produced faster, launched sooner, and scaled efficiently. (3/3)

In just a few years, we've advanced our radiation-annealing Si solar tech from flexible coupons to 1-meter modules, and even to a 5.5-meter long deployable blanket. Each step reflects our team’s rapid iteration, disciplined engineering, and commitment to redefining space solar.

What will you build with flexible, low-mass Si solar power modules that self-heal radiation damage? With lead times measured in months, not years, Solestial’s tech is engineered to accelerate your mission timeline while delivering durable, high-performance power on orbit. ☀️🚀
