In this paper, the potential for a solar- thermal system for hot water generation has been studied. A parabolic trough concentrator is made of an aluminum sheet which is covered by a cloth on which rectangular mirror strips (1.20mx 0.05m) are pasted.

A parabolic trough collector (PTC) is a linear concentrating system made of long, parabolic-shaped mirrors and a receiver tube placed along the focal axis of the parabola. DNI is concentrated onto the receiver tube (as illustrated in Fig. 16.8), where solar energy is absorbed by the HTF.A glass envelope is often placed around the HCE to limit convection losses and
The reflector sheet is loaded by end pressure against the parabolic shape cut into the transverse ribs to generate the parabolic trough shape. A second sheet of material is required on the back surface of the ribs for strength and to keep wind pressure from lifting the reflector sheet off the front surface of the ribs.
Jun 06, 2016 Many future solar power plants will use very large numbers of parabolic mirror collectors. Moreover there are several practical reasons (cost, thermal radiation and convection losses) to keep the dimensions of aparabolic mirror small. Hence, methods for designing high quality parabolic mirrors at relative low cost, such as the one discussed in this paper, are
Standard kitchen aluminum foil can work well as a solar cooking reflective material. This common material has been, and continues to be used, in homemade solar cookers. It can be glued with white glue or wheat paste. However, a few wrinkles may result from the glueing process. Also, while the reflective surface does not get hot to the touch in sunlight, there will
I made one of wood for the basic structure, no cement. Used thin sheet metal for the curve of the trough and lined it with reflective gift wrap. Put a one meter long 32 mm aluminum tube painted black at the focus. Good construction will show a bright straight line proyected on a white sheet of paper when placed at the focus and aimed at the sun.

Solar Cookers. A solar cooker is a type of solar thermal collector. It “gathers” and traps the Sun's thermal (heat) energy. Heat is produced when high frequency light (visible and ultraviolet) is converted into low frequency infrared radiation. Ultraviolet and visible light easily pass through glass, however when they strike a darkened ...
Aluminum alloy is generally used as the material of heat absorbing plate of flat solar collector. The advantages of wing-tube heat absorber are: high thermal efficiency, the tube and the plate are integrated, without combined thermal resistance; strong pressure resistance, aluminum alloy tube can withstand higher pressure.
Cardboard or poster board are the easiest materials to use when creating a parabola, but if you can give a little extra time, effort and expense you could create a quality parabolic cooker by

The unattended parabolic solar cooker [1] requires an imprecise parabolic reflector. Such a reflector can be molded or stamped in quantities, much like a salad bowl or a baby wading pool. However before it is commercially available, you can make one at home. The easiest way is to cut and fold a flat sheet into a parabolic dish.

Parabolic Mirror. The mirror includes a flexible material with a reflective surface and a rear surface. A flexible band is in contact with the rear surface of the flexible material. The bending stiffness of the band as a function of distance along its length is selected so that the band and the flexible material in contact therewith assume a parabolic shape when ends of the band are
