High-efficiency IBC monocrystalline silicon
Interdigitated back-contact architecture optimized for the AM0 spectrum. Target 26% BOL, >22% EOL after a 7-year LEO mission.
Stealth · founded 2026
Space-grade solar cells,
built for the constellation era.
Procyon Solar Technology manufactures high-efficiency monocrystalline silicon solar cells engineered for LEO smallsat constellations — aerospace reliability at a price-per-watt that closes the business case for the next 10,000 satellites.

Technology
A high-volume manufacturing approach to space photovoltaics.
Silicon is the workhorse of terrestrial solar — but space-grade cells have been built like jewelry for decades. We bring high-yield IBC silicon manufacturing to orbit, with the radiation tolerance and qualification rigor space demands.
Wafer-scale automation
Tooling adapted from gigawatt-scale terrestrial silicon lines. Cost per wafer drops an order of magnitude vs. legacy space-grade processes; yield improves with every cycle.
Radiation-tolerant for LEO duty cycles
Optimized base resistivity, rear-side passivation, and CMG coverglass hold >85% of initial power through a 7-year LEO mission profile.
Capabilities
From wafer to qualified flight hardware.
- Cell sizes Standard 30×40 mm and 40×80 mm; custom geometries on request.
- CIC assembly Coverglass-interconnected cells with CMG 100 or CMX 100 ceria-doped coverglass.
- Panel layup Rigid honeycomb and flexible substrates; in-house stringing and lamination.
- Qualification AIAA S-111 / S-112, ECSS-E-ST-20-08; full LAT and acceptance test reports per lot.
- Lead time 12 weeks for engineering quantities, 20 weeks for flight lots — targeting 8 weeks at maturity.
- Heritage Founders shipped >500 kW of space PV at prior programs across LEO, MEO, and GEO.
Why now
The constellation economy needs a new supply chain.
Launch cost has fallen 20× in a decade. Bus cost has followed. Power generation hasn't — and it's now the dominant cost line on a smallsat BOM. That's the gap we close.
~25,000
Satellites planned through 2030
Approved and proposed LEO constellations — each needing 0.5 to 5 kW of qualified space-grade power.
2 suppliers
Dominate Western supply
Lead times stretch 18+ months. Pricing reflects a duopoly built for exquisite GEO missions, not high-cadence LEO production.
$2.4B
Addressable market by 2030
Space photovoltaics, growing at a 14% CAGR as constellations move from deployment to refresh cycles.
ITAR-free path
Manufactured in the U.S.
Domestic fab, exportable variants under EAR for allied programs — a supply chain primes can underwrite.
About
Built by people who've shipped to orbit.
Procyon Solar Technology was founded in 2026 by a team of silicon process engineers, panel integrators, and space-systems leaders. We've spent careers shipping high-volume photovoltaics and we think the next decade of space depends on doing it faster, cheaper, and at a volume the industry has never attempted.
We're hiring across cell process, panel integration, test, and operations. Talk to us.
