Appendix B: Special Configurations
Many roofs will have various installation configurations or situations that require certain Support/Ballast
Tray installation configurations. This section covers some of these situations, such as inside corners with
northern exposure and roof cricketing or roof waviness.
Inside Corners with Northern Exposure to Wind
1.
The northern exposed part of the array is assembled in the same manner as the north row, with
the Supports flipped 180° and tucked under the module.
Figure 11 Inside Corners with Northern Exposure to Wind
Roof Cricketing or Roof Waviness
1.
Shim Pads may be used to raise the height of a Support to smooth out the array and prevent
module shading. Multiple Shim Pads may be used to achieve greater levels of height
adjustment.
2.
Shim Pads must be placed where the end of the Ballast Tray comes in contact with the roof. A
Shim Pad must be installed in one of the two holes in the end of the Ballast Tray. These two
holes allow for different heights of shimming.

On northern exposed modules
the Supports and Ballast Trays
are rotated 180°.
