In space-based solar power generation, sunlight is gathered in geostationary orbit and transmitted to a receiver on earth. (...)
satellite-based solar panels can capture the energy around the clock and are not affected by weather conditions.
If implemented, microwave-transmitting solar satellites would be set up approximately 35,000 kilometers from earth. Jaxa says that a receiver set up on earth with an approximately three-kilometer radius could create up to one gigawatt of electricity, which is about the same as one nuclear reactor.
