A Solar Parabolic Dish is a type of Solar Collector that uses a parabolic reflector to focus sunlight onto a central receiver, where the solar energy is absorbed and converted into heat. It accomplishes this through the use of a computer and dual-axis tracking. In the front area of the dish, the receiver is frequently mounted at the focal point.
