INSTALLATION WORK
6.1 PREPARING SHINGLE ROOF FOR INSTALLATION
1. Locate roof rafters or trusses.
Here are 3 options to finding the locations:
A.
Locate and measure the locations of the rafters
in the attic or at the outside eave and transfer
measurements to the roof.
B.
Use a hammer or rubber mallet to tap the roof and
locate the rafters. This will work with a cap sheet
or composition roof.
C.
Scan the roof with a high sensitivity stud finder.
2. Once the rafters have been located, snap a vertical
chalk line on every rafter to identify the location.
3.
Measure up from the eave 16" (400 mm) in at least
3 locations. Snap a chalk line. This marks the location
of the bottom edge of the slider feet.
No
te: This line needs to be 0.22" (5.5 mm) away from
the nearest front edge of shingles.
4.
Measure up from chalk line 0.8" (20 mm) and snap a
new chalk line. This marks the location of the bottom
edges of the modules.
5.
Measure up from the module chalk line to the desired
module height to form the array. Snap horizontal lines
at the measured locations for each row of rail.
6.
Mark and layout solar module vertical lines.
Note: modules should not fall in shaded areas.
