# Roof Spec # This is an example of a comment # Edit the following configuration for your rooftop: # Firstly the Roof Geometry in following format: # Roof: x <x-axis-side-size>, y <y-axis-side-size>, yaxis-south-angle <angle of y axis with South> shadow-at-height <height from ground at which shadow is calculated> Roof: x 10.3, y 14, yaxis-south-angle 45 shadow-at-height 0.3 # Note: Units for all distances in the roof specification are up to the user. The only # requirement is that same units must be used for all parameters. # Specify Blocks on the roof that cause shadows in the following format: # Block: name <block-name> height <height> Coordinates <x y coordinates of four corners of the block> Block: name Duct height 2 coordinates 5.6 10.8 5.6 14 10.3 14 10.3 10.8 Block: name Duct height 2 coordinates 3.3 0 3.3 1.2 6.8 1.2 6.8 0 Block: name Tank height 5.75 coordinates 0 9.9 0 14 4.7 14 4.7 9.9 # Placement of panel or a row of panels in following format: # Panel: center <x y coordinates of center of panels> length <length of panels> width <width of panels> base-height <height of the base of panels from ground> align south|x|y # alignment of width of panel to south direction or x axis of roof or y axis of roof Panel: center 6.8 2.1 length 1.4 width 1.9 base-height 0 tilt 30 align south Panel: center 1.5 1.5 length 3 width 2 base-height 1.5 tilt 18 align y Panel: center 9 5.5 length 2 width 5 base-height 1.5 tilt 0 align y
