Beam-down towers

Definition

Beam-down towers are a type of concentrated solar power (CSP) technology that utilizes mirrors to focus sunlight onto a receiver located on the ground. This design differs from traditional solar power tower systems, which typically have the receiver at the top of a tall structure. By collecting and converting solar energy at ground level, beam-down towers can improve efficiency and reduce heat losses associated with high-temperature operations.
