Space-Based Solar Power (SBSP) Market Size, Share, Growth,

Dublin, Nov. 06, 2026 (GLOBE NEWSWIRE) -- "Space-Based Solar Power (SBSP) Market Size, Share, and Industry Analysis - Global Forecast to 2036" has been added to ResearchAndMarkets.com's offering.

The global space-based solar power market was valued at USD 380.0 million in 2025 and is expected to increase from USD 460.0 million in 2026 to USD 4.83 billion by 2036. This represents a CAGR of 26.5% during the 2026-2036 forecast period. The report evaluates market architectures, enabling technologies, demonstration missions, national programs, regulatory conditions, costs, funding activity, patents, and the competitive landscape.

Commercial electricity sales are expected to remain limited until the 2030s. Consequently, current market value primarily reflects spending on research programs, demonstration hardware, spacecraft, launch services, in-space assembly, ground infrastructure, and early power delivery services.

Market Drivers and Challenges

Energy security is a major driver of space-based solar power investment. Systems operating in geostationary orbit could provide highly available clean energy with limited disruption from weather, seasonal variation, or nighttime conditions. This potential is particularly relevant to energy-importing countries and supports government-backed initiatives such as ESA's SOLARIS program.

Lower launch costs, reusable rockets, and rideshare missions are also improving the market outlook. NASA has reported that launch and manufacturing represent more than 90% of lifecycle costs for large space-based solar power systems. Continued progress in spacecraft manufacturing, photovoltaic efficiency, autonomous servicing, and operational lifetime could substantially improve project economics.

Cost remains the primary market restraint. NASA's January 2024 analysis of two 2-gigawatt reference designs estimated electricity costs of USD 0.61 and USD 1.59 per kilowatt-hour, compared with USD 0.02 to USD 0.05 for terrestrial renewable energy. However, combined technology and launch improvements could reduce space-based solar power costs to between USD 0.03 and USD 0.08 per kilowatt-hour.

Additional barriers include the need to place millions of kilograms of equipment in orbit, develop large-scale robotic assembly and servicing capabilities, reduce energy losses, and establish commercial licensing frameworks. Spectrum allocation, beam safety, airspace management, orbital debris, disposal requirements, public acceptance, and competition from declining terrestrial solar, wind, and storage costs will influence adoption.

Commercial Opportunities

Defense and remote operations represent the most immediate commercial opportunities because dependable power can command significantly higher prices in locations that rely on exposed or expensive fuel supply chains. Aetherflux received Pentagon operational energy funding in fiscal 2025, highlighting growing defense interest.

In-space power transmission also offers potential for satellite-to-satellite energy delivery and lunar missions, particularly during the 14-day lunar night. Longer-term opportunities include utility and data center supply agreements. The International Energy Agency projects global data center electricity consumption will rise from approximately 415 terawatt-hours in 2024 to about 945 terawatt-hours in 2030, increasing demand for firm clean energy.

Emerging agreements include a reported capacity reservation of up to 1 gigawatt between Overview Energy and Meta, along with Space Solar's planned 30-megawatt pilot project with Reykjavik Energy. Other important trends include modular low-orbit constellations, laser power transmission, state-backed development in China and Japan, early capacity reservations as financing tools, and reusable heavy-lift launch services.

Segment Outlook

The report analyzes the space-based solar power market by component, transmission technology, orbit, development stage, application, end user, and geography.

Component: The space segment is expected to account for the largest market share in 2026 as funding remains concentrated on demonstration spacecraft, solar arrays, transmitters, deployable structures, and spacecraft buses. Launch & in-space assembly services are projected to record the highest CAGR as pilot projects require greater orbital mass and robotic construction.

Power transmission technology: Microwave transmission is expected to lead in 2026, supported by OHISAMA, Caltech's MAPLE experiment, China's development program, and SOLARIS system studies. Laser transmission is projected to grow fastest because modular low-orbit systems can use smaller receivers. Reflected sunlight remains a separate commercial pathway for extending operating hours at terrestrial solar facilities.

Orbit: Low Earth orbit is expected to hold the largest share in 2026 because near-term missions can use rideshare launches and shorter development cycles. Geostationary orbit is forecast to register the highest CAGR as pilot and utility-scale projects pursue near-continuous solar exposure.

Development stage: Current spending is concentrated on feasibility studies and in-orbit demonstrations. Market value is expected to shift toward pilot systems during the forecast period, followed by early commercial operations around 2030.

Application: Defense & remote operations are expected to lead in 2026. Utility & data center power is projected to grow at the highest CAGR as operators seek reliable clean electricity and developers secure future offtake commitments.

End user: Government & space agencies are expected to remain the largest end-user group in 2026. Utilities & energy companies are forecast to expand fastest as pilot projects move toward delivery and power buyers reserve future capacity.
