# Source Energy

> Source Energy is a Colorado spacecraft-power manufacturer applying terrestrial solar manufacturing methods to satellites. Its standardized silicon modules, rigid panel wings, flexible blanket arrays, design work, and integration services are aimed at commercial, defense, telecom-constellation, specialty-mission, and on-orbit-compute customers that cannot tolerate legacy pricing or long procurement cycles.

- **Founded:** 2021
- **Headquarters:** Longmont, United States
- **Founders:** Philip Keller (CEO and Co-Founder), Bryan Mazor (CTO and Co-Founder)
- **Team size:** About 19 employees
- **Products:** Space-grade solar modules, Rigid panel arrays, Flexible blanket arrays, Array design services, Array integration services
- **Notable:** Shipped its first qualified primary power solution 14 months after incorporation., Supplied the primary solar arrays for Impulse Space's Mira OTV and gained on-orbit heritage in 2023., Raised a $6.5 million seed round led by Alpine Space Ventures in June 2023.

## Products & services

- **Space-grade solar modules** — Standard monocrystalline-silicon modules led by the available MOD-0015-02, with additional silicon and CIGS power classes on the roadmap.
- **Rigid panel arrays** — A standardized 183-watt honeycomb panel used body-mounted or combined into one-to-five-panel deployable wings up to 915 watts.
- **Flexible blanket arrays** — Z-fold photovoltaic blankets and complete strain-energy-deployed pantograph wings in standard 4, 10, and 24 kilowatt classes, with first deliveries planned for 2027.
- **Array design services** — Semi-custom power-budget, structural, thermal, configuration, and test-plan engineering based on proven platforms.
