CONCENTRATING SOLAR ENERGY COLLECTOR
Systems, methods, and apparatus by which solar energy may be collected to provide heat, electricity, or a combination of heat and electricity are disclosed herein.
1 . A method of manufacturing a reflector for a solar energy collector comprising;
placing a plurality of linear reflective elements arranged side-by-side on a reflector tray with a long axes of the linear reflective elements parallel to a long axes of the reflector tray; and
bonding the linear reflective elements to the reflector tray.
2 . The method of claim 1 , wherein the linear reflective elements are placed side-by-side with a gap between each of the linear reflective elements.
3 . The method of claim 1 , wherein the linear reflective elements are bonded to the reflector tray with an adhesive.
4 . The method of claim 3 , where the adhesive covers the entire bottom surface of each linear reflective element.
5 . The method of claim 3 , wherein the adhesive seals the edges and bottom surface of the linear reflective elements.
6 . The method of claim 3 , wherein the adhesive fills in the gaps between the plurality of linear reflective elements.
7 . The method of claim 1 , wherein the reflector tray comprises a flexible material.
8 . The method of claim 7 , wherein the flexible material is sheet metal.
9 . The method of claim 1 , wherein portions of the reflector tray that comprise the combination of the reflector tray and the linear reflective elements have a stiffness greater than the portions of the reflector tray positioned between the linear reflective elements.
10 . The method of claim 9 , wherein an adhesive is used to bond the linear reflective elements to the reflector tray.
11 . A method of assembling a solar energy collector comprising;
placing a reflector tray comprising a plurality of linear reflective elements arranged side-by-side with the long axes of the linear reflective elements parallel to a long axis of the reflector tray over a transverse reflector support;
bending the reflector along a short axis of the reflector tray to form a curvature substantially equal to a curve of the transverse reflector support;
aligning complementary self-locking features of the reflector tray with the self-locking features of the transverse reflector support; and
applying pressure to the reflector such that the self-locking features engage in a self-locking manner to secure the reflector tray to the transverse reflector support.
12 . The method of claim 11 , wherein the bending of the reflector tray stores energy in the reflector tray tending to return the reflector tray to the non-bent state if left unrestrained.
13 . The method of claim 11 , wherein the linear reflective elements are placed side-by-side with a gap between each of the linear reflective elements.
14 . The method of claim 11 , wherein portions of the reflector tray that comprise the combination of the reflector tray and the linear reflective elements have a stiffness that is greater than the portions of the reflector tray positioned between the linear reflective elements.
15 . The method of claim 14 , wherein the reflector tray bends primarily at the positions between the linear reflective elements.
16 . The method of claim 11 , wherein the self-locking feature of the reflector tray is a tab having a hooked shaped profile.
17 . The method of claim 11 , wherein the self-locking features of the transverse reflector support are openings that receive a portion of the self-locking feature therethrough for self-alignment of the self-locking feature on the reflector tray.
18 . The method of claim 11 , wherein the curve of the transverse reflector support is, upon installation on the reflector support, substantially parabolic.
19 . The method of claim 11 , wherein the reflector tray is scored or creased the length of the reflector tray at positions between the linear reflective elements.
20 . The method of claim 11 , wherein the reflector tray has linearly extending pre-bent angled sections positioned between the linear reflective elements.
21 . The method of claim 11 , wherein the reflector tray comprises a flexible sheet metal.
