ELSA
The Extensible Low-Profile Solar Array. Engineered for performance. Designed for Production.
ELSA can provide 50% more power by volume than traditional arrays.
Overview
About ELSA
An innovative new power solution designed to minimize solar array stowed volume and mass, while remaining competitive with conventional solar array technology price and performance. Leveraging Redwire’s experience with flexible substrates from our flight-proven ROSA technology, ELSA stacks 50% more frames in the same stowed volume of a traditional Solar Array, without compromising on performance or cost. Designed for production and rapidly available to support upcoming missions.

Powering Moog’s Meteor Spacecraft Platform
Redwire’s ELSA solar array wings will be integrated with Moog’s METEOR satellite bus in support of a Low Earth Orbit (LEO) mission for an undisclosed national security customer.
Additionally, ELSA has been baselined by Moog as a standard component of their METEOR ESPA-Grande satellite bus.
METEOR is all-orbit capable and available for use on a wide variety of missions and flight profiles, including pathfinder constellation missions and other disaggregated architectures.
