Abstract
A solar collector includes a transparent envelope and an absorber panel extending therethrough, the transparent envelope being constituted of a transparent plastic tube of smaller diameter than the width of the absorber panel such that the absorber panel supports the transparent plastic tube in an oval shape. In the described method of making the solar collector, a transparent plastic sheet is first bent into a right circular cylinder with its longitudinal edges secured together; and then a rigid absorber panel, having a width greater than the diameter of the cylinder, is inserted into the cylinder to deform it into an oval shape.
