Claims

1 . A substantially rigid thin-sheet panel assembly configured as a truss and having a non-rigid thin-sheet component, the thin-sheet panel assembly comprising the thin-sheet component which has selected plan area and shape and is a first chord of the truss, a backer having a plan shape and area substantially similar to the thin-sheet component and being a second chord of the truss, and plural riser elements of selected height and configuration each extending from the backer to distal ends connected to a reverse surface of the thin-sheet component, the riser elements being diagonal elements of the truss and configured and disposed in an array which causes the assembly to have substantial rigidity in a selected direction in the thin-sheet component, wherein the thin-sheet panel assembly further comprises a bar coupled to the backer and extending between at least one pair of adjacent riser elements of the plural riser elements in a direction substantially parallel to the reverse surface of the thin-sheet component.

2. The thin-sheet panel assembly of claim 1 in which the riser elements are of substantially uniform height from the backer.

3. The thin-sheet panel assembly of claim 2 in which an obverse surface of the thin-sheet component has parabolically cylindrical concave curvature.

4. The thin-sheet panel assembly of claim 1 in which the thin-sheet component includes a glass layer.

5. The thin-sheet panel assembly of claim 1 in which the backer is defined by a backer sheet, and the riser elements are defined by portions of the backer sheet that are bent away from the backer sheet and have integral connections to the backer sheet.

6. The thin-sheet panel assembly of claim 5 in which the portions of the backer sheet that define the riser elements have substantially hourglass-shaped configurations and the integral connections to the backer sheet are at bases of the hourglass-shaped configurations.

7. The thin-sheet panel assembly of claim 6 in which the integral connections of the riser elements to the backer sheet are spaced along substantially parallel lines, and the riser elements are in substantially parallel planes.

8. The thin-sheet panel assembly of claim 7, wherein the bar extends between the substantially parallel planes.

9. . The thin-sheet panel assembly of claim 5 in which the riser elements at their distal ends define connection tabs disposed laterally of the heights of the riser elements.

10. The thin-sheet panel assembly of claim 5 in which the riser elements at their distal ends define respective pairs of connection tabs disposed laterally of the heights of the

riser elements, the connection tabs of each pair of connection tabs extending in opposite directions from the distal end of the respective riser element.

1 1 . The thin-sheet panel assembly of claim 5 in which the backer sheet comprises aluminum.

12. The thin-sheet panel assembly of claim 1 in which the connections of the distal ends of the riser elements to the reverse surface of the thin-sheet component are bonded connections.

13. The thin-sheet panel assembly of claim 1 in which the thin-sheet component includes a substrate layer composed principally of a selected synthetic resin material.

14. The thin-sheet panel assembly of claim 1 in which the thin-sheet component is reflective of electromagnetic radiation.

15. The thin-sheet panel assembly of claim 1 in which the thin-sheet component is reflective of solar radiation.

16. The thin-sheet panel assembly of claim 1 , wherein a first surface of the thin-sheet component opposite the reverse surface includes at least a portion of a curved reflective surface having a selected curvature for directing and concentrating sunlight onto a receiver of a solar power generation facility.

17. The thin-sheet panel assembly of claim 16, wherein the bar is attachable to a trough frame supporting the curved reflective surface.

18. The thin-sheet panel assembly of claim 1 , wherein the bar has a hexagonal cross-sectional shape.

19. A support structure for supporting a thin panel to have a substantially rigid configuration, the support structure comprising a backer sheet, and a plurality of riser elements having heights extending in a first direction from proximal ends coupled to the backer sheet to distal ends and having lengths along rows in substantially parallel riser planes, the distal ends of the riser elements being attachable to the thin panel for supporting the thin panel and increasing rigidity of the thin panel in a second direction substantially parallel to the riser planes, wherein the backer sheet is configured to be a first chord of a truss and the riser elements are configured to be diagonal elements of the truss, the thin panel being a second chord of the truss, wherein the support structure further comprises a bar extending between at least one pair of adjacent riser elements of the plurality of riser elements in a third direction substantially perpendicular to the first and second directions.

20. The support structure of claim 19, wherein the pair of adjacent riser elements are in a same one of the rows.
