1. A substantially rigid thin-sheet panel assembly configured as a truss andhaving a non-rigid thin-sheet component, the thin-sheet panel assembly comprising the thinsheetcomponent which has selected plan area and shape and is a first chord of the truss, abacker having a plan shape and area substantially similar to the thin-sheet component andbeing a second chord of the truss, and plural riser elements of selected height andconfiguration each extending from the backer to distal ends connected to a reverse surface ofthe thin-sheet component, the riser elements being diagonal elements of the truss andconfigured and disposed in an array which causes the assembly to have substantial rigidity ina selected direction in the thin-sheet component, wherein the thin-sheet panel assemblyfurther comprises a bar coupled to the backer and extending between at least one pair ofadjacent riser elements of the plural riser elements. 2. The thin-sheet panel assembly of claim 1 in which the riser elements are ofsubstantially uniform height from the backer so that the thin-sheet component and the backerhave essentially concentric curvature. 3. The thin-sheet panel assembly of claim 2 in which an obverse surface of thethin-sheet component has parabolically cylindrical concave curvature. 4. The thin-sheet panel assembly of claim 1 in which the thin-sheet componentincludes a glass layer. 5. The thin-sheet panel assembly of claim 1 in which the backer is defined by abacker sheet, and the riser elements are defined by portions of the backer sheet that are bentaway 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 backersheet that define the riser elements have substantially hourglass-shaped configurations andthe integral connections to the backer sheet are at bases of the hourglass-shapedconfigurations. 7. The thin-sheet panel assembly of claim 6 in which the integral connections ofthe riser elements to the backer sheet are spaced along substantially parallel lines, and theriser elements are in substantially parallel planes. 8. The thin-sheet panel assembly of claim 7, wherein the bar extends between thesubstantially parallel planes.-12-wo 2011/050329 PCT /US201 0/053856 9. The thin-sheet panel assembly of claim 5 in which the riser elements at theirdistal ends define connection tabs disposed laterally ofthe heights of the risers. 10. The thin-sheet panel assembly of claim 5 in which the riser elements at theirdistal ends define respective pairs of com1ection tabs disposed laterally of the heights of therisers, the connection tabs of each pair of connection tabs extending in opposite directionsfrom the distal end of the riser element. 11. The thin-sheet panel assembly of claim 5 in which the backer sheet comprisesaluminum. 12. The thin-sheet panel assembly of claim 1 in which the connections of thedistal ends of the riser elements to the reverse surface ofthe thin-sheet component are bondedconnections. 13. The thin-sheet panel assembly of claim 1 in which the thin-sheet componentincludes 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 isreflective of electromagnetic radiation. 15. The thin-sheet panel assembly of claim 1 in which the thin-sheet component isreflective of solar radiation. 16. The thin-sheet panel assembly of claim I, wherein a first surface of the thinsheetcomponent opposite the reverse surface includes at least a portion of a curved reflectivesurface having a selected curvature for directing and concentrating sunlight onto a receiver ofa solar power generation facility. 17. The thin-sheet panel assembly of claim 16, wherein the bar is attachable to atrough fran1e supporting the curved reflective surface. 18. The thin-sheet panel assembly of claim 1, wherein the bar has a hexagonalcross-sectional shape. 19. A support structure for supporting a thin panel to have a substantially rigidconfiguration, the support structure comprising a backer sheet, and a plurality of riserelements having heights extending in a first direction from proximal ends coupled to thebacker sheet to distal ends and having lengths along rows in substantially parallel riserplanes, the distal ends of the riser elements being attachable to the thin panel for supportingthe thin panel and increasing rigidity of the thin panel in a second direction substantially-13-wo 2011/050329 PCT /US201 0/053856parallel to the riser planes, wherein the backer sheet is configured to be a first chord of a trussand the riser elements are configured to be diagonal elements of the truss, the thin panelbeing a second chord of the truss, wherein the support structure further comprises a barextending between at least one pair of adjacent riser elements of the plurality of riserelements, the pair of adjacent riser elements being in a same one of the rows. 20. The support structure of claim 19, wherein the bar extends between the rowsin a third direction substantially perpendicular to the first and second directions. 21. The support structure of claim 19, wherein the riser elements are defined byportions ofthe backer sheet that are bent away from the backer sheet, have integralconnections to the backer sheet, and have substantially hourglass-shaped configurations withthe integral connections to the backer sheet being at bases of the hourglass-shapedconfigurations. 22. A substantially rigid thin-sheet panel assembly having a non-rigid thin-sheetcomponent, the thin-sheet panel assembly comprising the thin-sheet component which hasselected plan area and shape, and a backer having a plan shape and area substantially similarto the thin-sheet component, the thin-sheet component being attached to a first surface of thebacker, wherein the backer comprises a backer sheet including a plurality oflibs extendingtoward the thin-sheet component, and a substrate including the first surface and a plurality ofprojections extending from a second surface opposite the first surface, each of the projectionshaving a slot at a distal end and receiving an end of a corresponding one of the ribs therein toform an interlocking joint. 23.
