Abstract: A thermal management system (“TMS”) for controlling the temperature of a selective reflective panel is disclosed. The TMS includes a solar concentrator array, a temperature sensor, and a controller. The solar concentrator array is located within the selective reflective panel and has a plurality of reflectors arranged in reflector groups.
