DeSoto Solar
Dish Absorber Geometry

 
Introduction

This approach to maximizing parabolic dish absorber efficiency is based on the already described method of maximizing absorption for parabolic troughs.

The above drawing shows a half cross-section of the absorber surface which is rotated to form a 3D object:

This grooved hemispherical object will exhibit the same behavior as the V-grooved trough absorber.
