Size

Approximately 1,100 employees (source: asu.edu). Revenue figures are not disclosed as it is a private company (source: solestial.com).

What They Do

Solestial specializes in silicon photovoltaics engineered specifically for space applications, focusing on the development of radiation-hardened solar cells, modules, and arrays designed for satellites and spacecraft (source: solestial.com). Their core technology features ultrathin, flexible silicon heterojunction solar cells that achieve efficiencies of up to 20%, with a Generation 2 product expected to be available in 2026 (source: solestial.com). These innovative cells are capable of self-annealing radiation damage at operating temperatures as low as 65°C, a significant advancement over traditional silicon cells that typically degrade in high-radiation environments (source: satnow.com). Solestial's product offerings include individual solar cells, flexible solar power modules, and complete solar arrays, all designed to meet the needs of various satellite constellations and missions (source: solestial.com). Their target markets encompass commercial satellite constellations in low Earth orbit (LEO), smallsats, CubeSats, and even lunar settlements, providing a cost-effective alternative to traditional III-V multijunction cells (source: satnow.com).

Projects & Track Record

While Solestial has not yet completed any fully operational flight projects, they have secured over $7 million in Small Business Innovation Research (SBIR) contracts from notable organizations such as NASA and the National Science Foundation (source: satnow.com). Recently, they were awarded a $1.2 million Direct-to-Phase II SpaceWERX contract to develop a rapidly manufacturable 1 kW solar array wing for U.S. Space Force small satellites, showcasing their innovative approach to solar technology (source: satnow.com). Ongoing projects include scaling their second-generation solar cells for flight deployments by late 2025, with production ramping to 1 MW/year through a partnership with Meyer Burger (source: solestial.com). Their key clients include EnduroSat AD, with whom they have a sales agreement for radiation-hardened modules on satellites launching in 2026, and DCUBED, with whom they debuted a new solar array product at the Space Tech Expo (source: solestial.com).

Recent Developments

In October 2025, Solestial announced a significant sales agreement with EnduroSat AD to supply radiation-hardened silicon solar power modules for next-generation satellites set to launch in 2026 (source: solestial.com). Earlier, in August 2024, they entered into a strategic manufacturing partnership with Meyer Burger, aiming to scale production to over 1 MW/year of ultra-thin cells and modules by mid-2025 (source: solestial.com). Additionally, Solestial received a $1.2 million SpaceWERX Direct-to-Phase II contract for a 1 kW smallsat solar array wing, further solidifying their position in the space solar market (source: satnow.com). The company also achieved a significant milestone when the CEA validated their low-temperature radiation-curing technology, confirming its effectiveness in self-recovery at operating temperatures (source: solestial.com).

Working There

Solestial is focused on fostering innovation-driven growth, particularly in roles related to manufacturing, research and development, engineering, and operations to support the rapid scaling of solar cell and module production at their Tempe facility (source: solestial.com). The company is actively hiring for positions at their headquarters and the newly opened Warner manufacturing plant, with a focus on mass-producing thin wafers, cell metallization, and module integration (source: solestial.com). Departments likely include solar cell engineering, module assembly, quality testing, and business development, reflecting their roots in advanced research from Arizona State University (source: asu.edu). The company culture is characterized by a dynamic growth environment and a relentless pursuit of innovation, with team members sharing a passion for solar technology and collaboration with customers (source: solestial.com). While specific benefits are not detailed in available sources, the careers section invites individuals passionate about space solar innovation to join their team (source: solestial.com).
