The James Webb Space Telescope’s 20-foot solar array will provide all the power the observatory needs, by converting sunlight into electricity. Webb’s solar array is its first, and most important deployment. The small yet efficient array will release itself like an accordion to a straightened configuration shortly after launch. The power it creates will help operate the telescope’s propulsion and communication subsystems, as well as its scientific instruments.
