Figure 4.8 North-South Drop-in, North-South Thermal Expansion Gap
Along the axis of the Interlock, large arrays also need a physical gap after two Thermal Expansion
Joints. For example, a North-South drop-in, Landscape orientation, might require a physical gap
approximately every 30 meters or 100 feet. This would be approximately every 18 module lengths,
depending on the module.
