Beam-down systems

Definition

Beam-down systems are a type of concentrated solar power technology that utilize heliostats to direct sunlight to a receiver located on the ground or at a lower elevation, rather than at the top of a tower. This setup allows for increased efficiency in energy capture and easier integration into the landscape, as it eliminates the need for tall structures typically associated with traditional solar tower systems.
