                  Shading & Blocking
• A field of heliostats suffers losses caused

    by shading and blocking by neighboring

    heliostats.

• The shading and blocking should be

    calculated for different ∆R and ∆Az.

• ∆R is the radial spacing.

• ∆Az is the Azimuthal spacing.

             Problem Specifications
 • Find the equation of the plane of target mirror.
 • Find the co-ordinates of the target mirror on the
   absolute coordinate system.
 • Find the co-ordinates of the source mirror on the
   absolute coordinate system.
 • Compute the sun vector(X,Y,Z) in the absolute
   coordinate system.
 • Compute the projections of the source mirror corners
   with respect to sun vector on to the target mirror
   plane.
 • Compute the intersection area of the target mirror and
   the projected plane.

                    Implementation

 Once the shading and blocking between two mirrors is

    achieved it can be implemented on to eight mirrors.

 The distance between the mirrors can be varied.

 The Shading and Blocking for different values of ∆R and ∆Az

    are to be noted and stored.
