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.
