(a) Classification of the remote sensing image into two classes of (i) roof surface; and (ii) others within the area of interest denoted by black polygon. The roof surfaces under the white crosses with the white rectangles were excluded from further consideration (as there were not oriented to either south or south-west directions). (b) an extended view of a roof surface, where the dotted black boxed area was only considered as suitable for harvesting the greatest amount of incident solar radiation.
