A solar power transmission system having a solar-microwave fabric for absorbing sunlight, transforming the sunlight into electrical energy, amplifying a received signal using the electrical energy, and transmitting the amplified signal to a rectenna beacon. Embodiments according to the present invention include a system for space-based solar power transmission having a solar power collection balloon in geostationary orbit around Earth, which allows for continuous, feasible, and efficient collection of solar power in space that can be packaged into a condensed canister for launch and deployed without manual or machine assembly once in orbit.
