Technology & Innovations

AREVA Solar’s core technology is the Compact Linear Fresnel Reflector (CLFR) solar collector and steam generation system.

It uses modular flat reflectors to concentrate the sun's radiation onto central elevated receivers (1) supported above the reflector field. These receivers consist of a system of tubes through which water flows (2). Boiler tubes in the receiver absorb solar energy, which is heated to produce superheated steam to(3). This steam then actionates a turbine which generates electricity.


AREVA's Compact Linear Fresnel Reflector concentrates over 50 “suns” of energy.

Many parallel Fresnel collectors with flat mirrors concentrate sunlight onto absorber tubes through which water is pumped. They generate superheated steam – for the generation of electric power or heat for industrial processes.
