Abstract: Process for manufacturing a support structure and a solar receiver includes the following steps: a) providing a sheet of rigid material having a rectangular shape with a first median axis and a second median axis; b) performing two grooves running from one sheet side to the opposite side, defining two parabolic curves, the parabolic curves having the same axes of symmetry, parallel to the second median axis, the grooves dividing the sheet in a central surface, a first and a second lateral surfaces; c) bending the first lateral surface out of plane with respect to the central surface through an angle ?1 along the first groove; bending the second lateral surface out of plane with respect to the central surface through an angle ?2 along the second groove; the central surface, first and second lateral surfaces being curved and the central surface having a profile defining a third parabolic curve.
