Parabolic trough reflectors are very efficient for heating fluids. Many are passive, while others utilize single-axis trackers to follow the sun. By increasing the operating temperature, troughs can be much more efficient than non concentrating solar collectors. There are a wide variety of designs for various applications. Parablic troughs represent one of the easiest forms of CSP to adopt for home owners.
HomeCSP is proud to introduce our plans for a compound parabolic reflector. The compound parabola utilizes a unique non-imaging optics technique which produces a focal plane rather than a focal point. All light within the angle of acceptance gets reflected to the focal plane. This results in minimal loss of efficiency with off axis light. With an angle of acceptance from 60 to 75 degrees and an east west orientation there is little need to use active tracking devices.
