Provided herein are linear solar reflectors and collectors, and methods of efficiently constructing such reflectors and collectors. The reflectors are made using reflective laminate sheets, which can be reinforced by tension-bearing strips. Methods and apparatuses for installing the sheets from a roll dispensing the sheets carried on a deployment vehicle are disclosed, as well as methods and apparatuses for assembling and constructing various collector components, methods and apparatuses for tensioning the reflective laminate sheets, methods and apparatus for passively changing the focal length of the reflectors while controlling their movement to track the sun, and methods and apparatuses for compensating for temperature changes in system components for moving the collectors, are provided.
