Space solar power is the proposal to launch a system into orbit that collects solar power, converts it to radio frequencies, and beams it to Earth for collection. Until now, there has not been a realistic and

Since clouds, atmosphere and nighttime are absent in space, satellite-based solar panels would be able to capture and transmit substantially more energy than terrestrial solar panels.

Space-based solar power (SBSP or SSP) is the concept of collecting solar power in outer space with solar power satellites (SPS) and distributing it to Earth.

Solar electric propulsion (SEP) is a means of creating in-space thrust for spacecrafts using solar cells to create electric power. SEP provides high fuel economy, albeit at a lower thrust, than traditional

Space-based panels generate 8-10 times more energy than ground-based equivalents because they face no atmospheric losses, no weather, no nighttime, and can be positioned for

These orbiting satellites, like their terrestrial counterparts, are equipped with enormous arrays of photovoltaic (PV) cells that directly convert solar energy into electricity.

However, most spacecraft in low Earth orbit or operating within the inner Solar System are powered by converting the Sun''s thermal energy into electricity. This process involves the use of

An SBSP system collects solar energy in space, converts that to microwave or optical laser energy, and transmits that energy to the Earth. A ground station receives the energy, converts it to electricity, and

The concept of harvesting energy directly from the sun in orbit and beaming it to Earth has transitioned from theoretical physics to active engineering validation. As of 2025, Space-Based
