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. Its advantages include a higher collection of energy due to the lack of reflection and absorption by the atmosphere, the possibility of very little night, and a better ability to orient to face the Sun. Space-based solar power systems convert sunlight
But technology is constantly evolving, and increasingly bold concepts are being developed, including using space-based solar power generators not only to power spacecraft but
Utilizing SBSP entails in-space collection of solar energy, transmission of that energy to one or more stations on Earth, conversion to electricity, and delivery to the grid or to batteries for storage.
Without atmosphere filtering and scattering, solar panels in orbit can absorb a wider spectrum and intensity of solar radiation, leading to a higher energy capture efficiency.
Unlike terrestrial solar farms, SBSP proposes a revolutionary approach: capturing solar energy in space, where it is perpetually available, unburdened by weather patterns, atmospheric
We propose a scalable and economically efficient system for SSP enabled by high-efficiency, radiation-hard solar cells; high-efficiency integrated circuits; flexible phased arrays; and
To be commercially viable, SSP must demonstrate significant scalability to address large energy demands and be able to significantly reduce cost per unit of energy. The technology roadmap
Waste Not 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.
