SolarSpace is developing a next-generation concentrated solar power (CSP) technology developed at the University of Arizona's Steward Observatory Mirror Laboratory. Lightweight mirror technology enabled the creation of some of the world's largest mirrors (9.2 m²) that focus sunlight. At the focal point, light enters a small power conversion unit (PCU) through a spherical lens, where it is converted into electricity by small, highly efficient multi-junction solar cells. Patented optics deliver 1,000-fold concentrated sunlight to the cells, distributing it evenly among them, resulting in extremely high overall efficiency. Multiple mirror modules are mounted on a lightweight, dual-axis tracker and aimed directly at the sun, maximizing total power output from sunrise to sunset. SolarSpace has licensed the Transmission Energy Efficiency System (TREES) from NASA and signed a Space Act Agreement with NASA.
