Can anyone explain how to define the partitioning (nb. of rectangles in height and nb. of rectangles in width and also the height and width) if I have a 4 string tracker, 3 string tracker and 2 string tracker (Single axis E-W tracking) and modules in 1 portrait in a table? How will it change for landscape orientation or if I have 2 portrait orientation? How does it affect the shading scene?
