Method for manufacturing a solar radiation absorber

Abstract

A method for manufacturing a solar absorber element forming a solar absorber of a solar receiver including providing a substrate, placing at least one projection within the substrate, and attaching the projection to the substrate with an attachment functionality operative to attach the projection to the substrate, thus defining the solar absorber element, the solar absorber being configured to allow a fluid to flow therein and be heated by solar radiation penetrating the projection of the solar absorber element.
