BSV Podcast 0175: Source Energy

Balerion Principal Aidan Daoussis sits down with Bryan Mazor, Co-Founder & CTO of Source Energy, to discuss industrializing solar power for space. Source is developing lower-cost, rapidly manufacturable solar arrays for spacecraft, applying lessons from SpaceX and terrestrial solar manufacturing to increase the availability of power in orbit. The conversation covers Source’s manufacturing strategy, space-rated solar technology, scaling toward megawatt production, and the company’s longer-term vision of becoming an energy provider for space. 00:00 – Introduction to Source Energy and the scarcity of power in space 04:43 – Bryan’s background at SpaceX and work on Starlink and Crew Dragon solar arrays 13:56 – How space solar panels differ from terrestrial systems 17:42 – Source’s tradeoffs: lower cost, rapid delivery, manufacturing scale, and reliability 20:20 – Mega-constellations, insourcing, and the opportunity for standardized solar products 23:29 – Building an assembly-line model for space hardware manufacturing 26:10 – Source’s long-term vision: becoming the energy company and “wall outlet” for space 29:35 – Scaling low-cost solar versus developing higher-performance technologies 31:06 – Perovskite tandems, lunar power, and future high-performance applications 33:44 – In-space manufacturing and producing solar cells from lunar resources 36:56 – Strategic distractions, government customers, and the challenge of serving different space markets 39:59 – Lessons from Starlink and SpaceX on first-principles design and mass manufacturing 44:27 – Standardization, block upgrades, and why “the product is the factory” 48:09 – Source’s evolution from first flight hardware to profitable product lines and Series A fundraising 51:12 – What investors misunderstand about the gap between space-industry narratives and near-term customer needs54:08 – Source’s next milestone: completing a production line designed to scale toward tens and eventually 100 megawatts annually This is a public episode.
