1. A guide rail for directing and retaining one or more slidably removable reflective sheets in a solar concentrator, and for maintaining the one or more slidably removable reflective sheets in a shape prescribed by the shape of the guide rail, the guide rail comprising a rail body, wherein the rail body comprises a first L-shaped longitudinal channel formed by first and second walls oriented substantially parallel to one another and joined at a substantially perpendicular angle to a third wall, wherein a fourth wall is joined to the first wall at an end opposite the third wall, and wherein the fourth wall extends toward, but does not touch, an unjoined end of the second wall to form an opening of the L-shaped channel for receiving a longitudinal edge of the one or more slidably removable reflective sheets. 2. The guide rail of claim 1, wherein the first L-shaped longitudinal channel comprises an outer portion and an inner portion wider than the outer portion. 3. The guide rail of claim 2, wherein the inner portion of each L-shaped longitudinal channel has a depth selected from 0.080 inches to 0.250 inches. 4. The guide rail of claim 2, wherein the outer portion of each L-shaped longitudinal channel has a depth selected from 0.050 inches to 0.125 inches. 5. The guide rail of claim 1, wherein the rail body further comprises a second L-shaped longitudinal channel. 6. The guide rail of claim 5, wherein the second L-shaped longitudinal channel comprises an outer portion and an inner portion wider than the outer portion. 7. The guide rail of claim 1, wherein the guide rail guides and retains longitudinal hemmed edges or longitudinal hook edges of the one or more slidably removable reflective sheets. 8. The guide rail of claim 1, wherein the rail body further comprises an additional longitudinal channel sized and shaped for attachment to a supporting rib. 9. The guide rail of claim 1, wherein the rail body is comprised of a top piece joined to a bottom piece and wherein the top piece and the bottom piece respectively define top and bottom surfaces of the first L-shaped longitudinal channel. 10. The guide rail of claim 1, wherein the rail body comprises a material selected from the group consisting of: a lubricious material, polyoxymethylene, aluminum, steel, a slip coating, polytetrafluoroethylene, an anodized coating and any combination of these. 11. The guide rail of claim 1, wherein the rail body further comprises one or more retaining means for retaining the one or more slidably removable reflective sheets along the longitudinal direction. 12. A concentrating solar collection assembly comprising the guide rail of claim 1 and a first slidably removable reflective sheet of the one or more slidably removable reflective sheets having a longitudinal edge retained in the first L-shaped longitudinal channel, wherein the first slidably removable reflective sheet extends transversely from the guide rail. 13. A reflective assembly for a concentrating solar collector comprising: a pair of guide rails for guiding and/or retaining longitudinal edges of one or more slidably removable reflective sheets;the one or more slidably removable reflective sheets having longitudinal edges mounted within L-shaped longitudinal channels of the pair of guide rails;wherein each guide rail comprises a rail body, wherein the rail body comprises a first L-shaped longitudinal channel formed by first and second walls oriented substantially parallel to one another and joined at a substantially perpendicular angle to a third wall, wherein a fourth wall is joined to the first wall at an end opposite the third wall, and wherein the fourth wall extends toward, but does not touch, an unjoined end of the second wall to form an opening of the L-shaped channel for receiving a longitudinal edge of the one or more slidably removable reflective sheets. 14. The assembly of claim 13, wherein the one or more slidably removable reflective sheets have thicknesses selected from 0.020 inches to 0.080 inches. 15. The assembly of claim 13, wherein the one or more slidably removable reflective sheets comprise a material selected from the group consisting of aluminum, steel, a reflective film and any combination of these. 16. The reflective assembly of claim 13 wherein the guide rails are shaped so as to define an optical surface of the one or more slidably removable reflective sheets. 17. The reflective assembly of claim 16 wherein the optical surface reflects a substantial portion of incident light to a solar receiver. 18. A reflective assembly for a concentrating solar collector comprising: a pair of guide rails for guiding and/or retaining longitudinal edges of one or more slidably removable reflective sheets;the one or more slidably removable reflective sheets having longitudinal edges mounted within channels of the pair of guide rails;wherein each guide rail comprises a channel in a supporting rib, wherein the supporting rib comprises a first L-shaped longitudinal channel formed by first and second walls oriented substantially parallel to one another and joined at a substantially perpendicular angle to a third wall, wherein a fourth wall is joined to the first wall at an end opposite the third wall, and wherein the fourth wall extends toward, but does not touch, an unjoined end of the second wall to form an opening of the L-shaped channel for receiving a longitudinal edge of one or more slidably removable reflective sheets. 19. The reflective assembly of claim 18 wherein the guide rails are shaped so as to define an optical surface of the one or more slidably removable reflective sheets. 20. The reflective assembly of claim 18 wherein the optical surface reflects a substantial portion of incident light to a solar receiver.
