DeSoto Solar
Dish Absorber Geometry


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.
