The present disclosure provides a method of fabricating a component of a solar energy system. The method comprises the step of providing a tube. The tube comprises a material that deforms when at least a length of the tube is exposed to a suitable difference in pressure between an interior portion of the length of the tube and an exterior portion of the length of the tube. The method also comprises providing a die having a cavity arranged to receive the length of the tube. The cavity defines a shape that is related to that of the component of the solar energy system. Further, the method comprises positioning the length of the tube in the cavity of the die. The method also comprises increasing a relative pressure of a fluid within the interior portion of the length of the tube relative to a pressure within the cavity and outside the interior portion of the length of the tube such that at least a portion of the length of the tube expands at to a shape that is related to that of the component of the solar energy system.
