A solar dish, or parabolic dish, is a device that uses mirrors to focus light coming directly from the sun to a point, for collection and use for power generation, thermal or thermochemical processes.The dish faces the sun and must be able to move to follow its path in the sky throughout the day. A solar dish has several key subcomponents, described here as
some types of solar dishes are mounted upon a frame with similar width to the reflector, and connected to a concrete or metal circular track on the ground via wheels.
