Reflect Orbital

Reflect Orbital, headquartered in Hawthorne, California, is a venture-backed space startup developing a constellation of sunlight-reflecting satellites designed to extend the productive hours of ground-based solar energy farms by redirecting sunlight onto solar panels during the hours immediately after sunset and before sunrise — addressing one of solar energy's core limitations: the mismatch between peak solar generation (midday) and peak electricity demand (evening).

Founded in 2021, Reflect Orbital is developing a constellation of 57 small satellites equipped with lightweight deployable mylar mirror structures — positioned in a low Earth orbit at approximately 373 miles (600 km) altitude — designed to track specific ground-based solar farms and reflect sunlight onto them for targeted illumination windows during twilight hours. The company estimates that even a 1-2 hour extension of productive solar generation per day could substantially increase the energy yield of utility-scale solar farms without requiring additional land or panel installation. The reflector satellites are designed to be slewed to target different solar farms across their orbital ground track, providing a flexible revenue model based on illumination time sold to multiple energy customers.

Reflect Orbital has raised $35.2 million in total funding, including a $28.7 million Series A led by Lux Capital and Sequoia Capital — a notable validation from two of Silicon Valley's most prominent deeptech venture firms. CEO Ben Nowack is a former SpaceX engineer who led propulsion development work, bringing operational launch vehicle and satellite deployment expertise to the company's technical execution.

The concept faces multiple technical and regulatory challenges: precise attitude control and pointing accuracy to deliver useful illumination density onto solar panel arrays, international dark sky and satellite brightness regulations from the International Astronomical Union (IAU), and the economics of illumination intensity — Earth's solar constant is 1,361 W/m² at TOA, but reflector efficiency losses, distance, and atmospheric attenuation reduce delivered flux significantly. Reflect Orbital competes conceptually with space-based solar power proposals but targets the nearer-term terrestrial solar extension market.
