Solestial has closed a $17M Series A round led by AE Ventures. Alongside the raise, we are thrilled to announce the appointment of Margo de Naray as CEO. Founding CEO, Stan Herasimenka, will assume the role of CTO. Read the complete press release:

Solestial has been selected by @SpaceWERXDOD for a $1.2M Direct-to-Phase II contract to develop a novel, fast to manufacture, multiorbital solar array wing concept for small satellites. Read more in our press release:

This 5.5 meter long, rollable integration was made using new manufacturing processes to produce larger, 1-meter-wide solar power modules. Our flexible solar cell technology improves total mass density and stowed volume while maximizing deployed array power density.

Last week, we opened our doors for a special Friends & Family Open House. It was a wonderful afternoon filled with tours of our manufacturing space, presentations, food and drink, and plenty of fun as Solestians shared their work with the people who support them every day.

Our sputtering tool is a specialized in-line coater used to deposit thin films onto our solar cells. This behemoth is roughly 50x larger than the tool we used in our pilot production line! . 📸: Pictured; Principal Engineer, Sergey

Luis and Sam, members of Solestial’s Module team, pose alongside our largest, most powerful delivery to date. This impressive assembly of solar blankets has been sent to our aerospace partner for rigorous third-party stress testing.

Thank you @phxbizjournal for nominating Solestial as a finalist for the 2025 AZ Inno Fire Awards presented by @azcommerce. The awards celebrate startups and founders in Arizona’s tech and innovation ecosystem, a community that we are proud to be a part of.

We were thrilled to host visitors from @YorkSpaceSystem. 📸 from right: Solestial’s Stan Herasimenka shows York’s Mike Lajczok and Francisco Hansen the new, larger form factor flexible solar power modules Solestial is developing to support rapidly scaling production capacity.

Excited to share Mitsubishi Electric's press release announcing its investment in Solestial!

On the heels of our $17M Series A fundraising round, we are recruiting 3 key positions: VP of Operations, VP of Product & Programs, and Quality Lead. Join our team as we scale our breakthrough solar technology for space! Learn more:

At Space Power Workshop, Stan Herasimenka presented Solestial’s work on flexible Si solar power modules compatible with next-gen roll-out arrays.☀️ Modules have a 5cm bend radius.☀️ They are low mass, reducing payload weight and launch costs.☀️ We work with many array partners

Solestial’s Vince Hearn joined customers at the Space Jam Launch Party, a Space Symposium event created by Atomic-6 and co-sponsored by Solestial, @TRL11_Inc, @StarpathSpace, @PortalSpaceSys, and @CisLunarInd. 📸 Vince with attendees and @CisLunarInd’s Tesla Lightning Gun

Join Stan Hersimenka for “Silicon Solar Power Modules for Roll Out Deployment" at @AerospaceCorp’s Space Power Workshop. Learn about Solestial’s work in developing flexible solar power modules compatible with roll out arrays and deployment systems on Wed April 30 at 1:15 PM.

Please join us in welcoming Damian, Nick, John, and Devin to the team! We are working diligently on technological innovation and upgrading our facilities; we’re building larger, flexible solar power modules faster than ever before to meet customer needs. Welcome aboard!
