The definition of a solar panel is a group of silicon panels under a glass substrate. The glass substrate of a solar panel allows light to shine upon the silicon surface and produce electricity from the movement of electrons on the atomic level. Solar panels work in both a direct and a diffuse light manner.
The mirror substrates are made of fused silica and incorporate a convex, off-axis, parabolic optical surface, mounting surfaces, and mirrored surfaces for use during. installation and alignment of the mirror into the COS instrument.
