4. Planning the Module Area
For installation, the QRails are fastened to the
building structure with roof attachments (e.g. flashed
roof attachments). The roof attachments must be
mounted at defined distances, depending on the
spacing of the supporting structure, the position on
the roof, and the site conditions. The layout should
be verified using the QDesign tool or a project-related
structural analysis by a qualified professional.
a Height of the module field: Number of modules
vertically x module length (+ any clearances)
b Width of the module array:
Using standard end clamps : Number of modules
horizontally x (module width + .75in ) + 2.4in. /61mm.
Using hidden end clamp: Number of modules
horizontally x (module width + .75in ).
c Vertical spacing of the base rails: Refer to module
manufacturer’s acceptable clamping zones or
mounting point locations.
d Horizontal attachment point spacing: Dependent
upon roof attachment method and site-specific
parameters.
e Distance between the modules = 0.75 in.
f Distance between module rows = 0.75 in. minimum, no maximum distance provided gap does not result in snow damming
DANGER
Risk of fatal injury due to falling. Falling from the roof can result in serious injuries or death.
 Please wear and use proper protective equipment.
 Secure yourself against falling.
 Do not perform any work in strong winds.
DANGER
Risk of fatal injury from falling objects. Parts falling from the roof can result in serious injuries or
death.
 Block off the hazard area on the ground prior to beginning work to prevent falling objects
injuring persons.
 Ensure that no parts can fall off the roof.
 Please wear required protective equipment.
 Do not linger in the hazard area.
 A er completion of the installation, re-check area for loose objects and re-check for proper
attachment of racking and modules.
