Space-based solar power costs in 2026: launch mass, rectenna investment, and path to competitive LCOE

Details the cost structure of space-based solar power systems: current estimates range from $2–12/W installed versus $0.70–1.20/W for terrestrial solar, driven by launch costs of $1,500–2,700/kg and GW-scale orbital assembly requirements. Analyzes how Starship-class vehicles at $100–500/kg could bring SBSP LCOE below $100/MWh by the late 2030s.

Space-based solar power vs terrestrial solar-plus-storage: cost, capacity factor, and scalability compared

Compares space-based solar power (SBSP) delivering 99% capacity factor via microwave or laser beaming against terrestrial solar-plus-battery systems averaging 25–30% capacity factor. SBSP demo costs exceed $10B while utility-scale solar+storage falls below $40/MWh. Evaluates technology readiness, timeline to commercial viability, and grid integration requirements.
