Space-Based Solar Power Market Report 2026

The space-based solar power market size has grown rapidly in recent years. It will grow from $1.71 billion in 2025 to $1.89 billion in 2026 at a compound annual growth rate (CAGR) of 10.7%. The growth in the historic period can be attributed to advancements in satellite and space launch technologies, early research into microwave power transmission, government-backed space energy programs, increasing interest in uninterrupted power supply concepts, availability of photovoltaic space systems.

The space-based solar power market size is expected to see rapid growth in the next few years. It will grow to $2.8 billion in 2030 at a compound annual growth rate (CAGR) of 10.4%. The growth in the forecast period can be attributed to increasing investments in space infrastructure, rising demand for continuous clean energy generation, expansion of international space energy collaborations, growing focus on energy security, advancements in laser and microwave transmission efficiency. Major trends in the forecast period include increasing development of large-scale orbital solar arrays, rising investment in wireless power transmission technologies, growing focus on space-based energy reliability, expansion of government-funded demonstration programs, enhanced integration of advanced control systems.

The growing emphasis on renewable energy is expected to drive the expansion of the space-based solar power market in the coming years. Renewable energy refers to power generated from natural sources that are constantly replenished, such as sunlight, wind, water, and geothermal heat. The increased focus on renewable energy is driven by concerns over climate change, as nations and industries look for sustainable solutions to reduce greenhouse gas emissions and lessen their reliance on fossil fuels. Space-based solar power improves renewable energy by providing a consistent and dependable source of solar energy, unaffected by weather or daylight conditions on Earth. For example, in December 2024, Eurostat, a Luxembourg-based government agency, reported that in 2023, renewable energy accounted for 24.5% of total energy consumption in the EU, up from 23% in 2022. Thus, the rising emphasis on renewable energy is fueling the growth of the space-based solar power market.

Key companies in the space-based solar power market are focusing on developing innovative solutions, such as advanced wireless power transmission, to boost energy efficiency and enable continuous power delivery from space. Advanced wireless power transmission refers to technology that allows the transfer of electrical energy over long distances without the use of physical wires, employing methods such as microwaves or lasers to effectively beam power from space to Earth. For example, in January 2023, the California Institute of Technology, a private research university in the U.S., launched the Space Solar Power Demonstrator (SSPD) into orbit to test essential technologies for capturing solar energy in space and transmitting it wirelessly, either in orbit or to Earth. The SSPD features a large, ultra-light composite structure designed for easy deployment in space, supporting scalable solar panel arrays. It carries 32 different types of solar photovoltaic cells to assess their durability and efficiency in the challenging space environment. Additionally, it includes a flexible microwave power transmitter capable of wirelessly sending solar energy in space, demonstrating crucial technology for future power transmission to Earth or other spacecraft.

In October 2023, Space Solar Group Holdings Limited, a UK-based company specializing in space-based renewable energy technology, partnered with Thales Alenia Space to develop commercial-scale space-based solar power (SBSP) systems. This collaboration aims to establish space-based solar power as a new baseload energy technology to aid the transition to net-zero and ensure global energy security, providing clean, affordable energy for the benefit of humanity and the planet. Thales Alenia Space S.A., based in France, is a provider of space-based solar power systems.
