Ultra Rail Configuration Tool
Verify Module Dimensions and Frame Color
|Rated Power||- W|
Configure each sub-array layout using the Sub-Array tabs. Modules may only be in one orientation per sub-array. For example, if a sub-array of portrait modules has the top row in a landscape configuration, move the landscape modules to a new sub-array.
Define the Edge / Corner zones of the array. Edge Zones and Corner Zones are high wind load zones near the edges of the roof and have a width defined by the building dimensions. Rails with attachments that lie within edge zones require additional attachments in order to obtain a shorter rail span. The edge zones and/or corner zones of the roof area shall be determined based on the building's least horizontal dimension (LDH). The Edge Zone distance, a, is equal to 10% of the LDH (a = .1 * LDH). Rail spans in the Edge and Corner Zones are specific values from the SnapNrack Structural Engineering Report and these rail spans will only apply to the roof attachments located within the Edge and Corner Zones (does not apply to modules or rails that overhang into the zone).
Module rails run left to right on screen (represented by red lines in array).
