A FOCAL DISPLAY PANEL FOR VISUAL OPTIMIZATION OF SOLAR COLLECTION

摘要

A focal display panel is situated in a parabolic solar energy collection array having reflective surfaces and a tube containing a working fluid to be heated. The panel comprises a target area to display patterns of light and shadow reflected from the array, and provides a visual means for determining the amount, if any, by which the focal point of the parabolic array misses the center of the tube containing the heated working fluid.
