Definition of space based solar power by Wikipedia:

Space-based solar power (SBSP) (or historically space solar powersolar power in space, for use on Earth. SBSP differs from the usual method of solar power collection in that the solar panels used to collect the energy would reside on a satellite in orbit, often referred to as a solar power satellite (SPS), rather than on Earth’s surface. In space, collection of the Sun’s energy is unaffected by the day/night cycle, weather, seasons, or the filtering effect of Earth’s atmospheric gases. (SSP)) is a system for the collection of

The world Radiation Centre’s 1985 standard extraterrestrial spectrum for solar irradiance is 1367 W/m².^[1] The integrated total terrestrial solar irradiance is 950 W/m².^[2] Therefore, extraterrestrial solar irradiance is 144% of the maximum terrestrial irradiance. A major interest in SBSP stems from the length of time the solar collection panels can be exposed to a consistently high amount of solar radiation. For most of the year, a satellite-based solar panel can collect power 24 hours per day, whereas a land-based station can collect for only 12 hours per day, yielding lower power collection rates around the sunrise and sunset hours.
