The EXA Deployable Multifunction Solar Array (DMSA) is designed for microsatellite missions. The array is available in configurations from 75W to 600W.

It consists of an embedded magnetorquer, sun and temperature sensors. The arrays also include embedded antennas that range from VHF to L bands. These antennas are embedded in their structure as 2 monopoles or 1 dipole and are designed to deploy with the solar array.

The arrays fold into a panel attached to the structure just as another solar panel and once in orbit it deploys to full extension, it also includes deploy and release contact sensors and its own deploy control board.
