Method for supporting a stretched membrane solar trough collector

A solar reflector comprising:

• A reflective membrane defining a first end and a second end, wherein the first end is attached to a first end form and the second end is attached to a second end form, and wherein each of the first and second end forms are adapted to hold the membrane in a desired shape;
• A frame comprising
• a first side beam region defining a first end and a second end,
• a second side beam region defining a first end and a second end,
• a first end beam region connecting the first end of the first side beam region and the first end of the second side beam region;
• and
• a second end beam region connecting the second end of the first side beam region and the second end of the second side beam region;
• and
• wherein the first end form is attached to the first end beam region, and the second end form is attached to the second end beam region;
• A support structure for supporting the frame;
• A first ridge cap-connected between the first side beam region and the second side beam region;
• A second ridge cap connected between the first side beam region and the second side beam region;
• wherein the first ridge cap is positioned near the first end beam region and the second ridge cap is positioned at a selected distance from the first end beam region;
• A first tensioned member defining a first end and a second end, wherein the first end of the first tensioned member is attached to the first ridge cap adjacent to the first side beam region, and the second end of the first tensioned member is attached to the second ridge cap adjacent to the second side beam region;
• and a second tensioned member defining a first end and a second end, wherein the first end of the second tensioned member is attached to the first ridge cap adjacent to the second side beam region, and the second end of the second tensioned member is attached to the second ridge cap adjacent to the first side beam region.
