SunFrame™ Code-Compliant Planning and Assembly
SunFrame components
1.
Rail
—Supports PV modules. Use 1 per row of modules
plus 1. Shipped in lengths of 16 feet. 6105-T5 aluminum extru-
sion, anodized (clear or dark bronze) to match PV module
frame.
2.
Cap strip
—Secures PV modules to rails and neatly frames
top of array. Use lengths equal to rail lengths. Cap strips are
sized for specifi c PV modules. Shipped in lengths of 16 feet
and predrilled every 16 inches. 6105-T5 aluminum extrusion,
anodized (clear or dark bronze) to match PV module frame.
3.
Self-drilling screw
(No. 12 x 1-1/2")—Use to secure each
cap strip (and PV modules) to rail, one per predrilled hole and
one within 8 inches of each end. 410 stainless steel, with or
without black oxide coating to match PV module frame.
4.
Rail splice
—Joins rail sections into single length of rail. It
can form either a rigid or thermal expansion joint. 8" long and
predrilled. 6105-T5 aluminum extrusion, anodized (clear or
dark bronze) to match PV module frame.
5.
Self-drilling screw
(No. 10 x 3/4")—Use 4 per rigid
splice or 2 per expansion splice. 410 stainless steel.
6.
End caps
—Use 1 to neatly close each rail end. Aluminum
plate (0.040"), clear anodized or black paint to match PV mod-
ule frame.
7.
Pan-head sheet metal screw
(No. 4 x 1/2")—Use 2 per
end cap to secure end cap to rail. 410 stainless steel; with or
without black oxide coating to match PV module frame.
8.
L-foot
—Use to secure rails either through roofi ng mate-
rial to rafters or to standoffs. Use no less than 1 L-foot per 4
feet of rail. 6105-T5 aluminum extrusion, anodized (clear or
dark bronze) to match PV module frame.
9.
L-foot bolt
(3/8" x 1-1/4")—Use 1 per L-foot to secure
rail to L-foot. 304 stainless steel.
10.
Flange nut
(3/8”)—Use 1 per L-foot bolt. 304 stainless steel.
Required torque: 30 to 35 foot-pounds.
11.
Standoff
(optional)—Use if L-foot cannot be secured directly
to rafter (with tile or shake roofs, for example). Sized to mini-
mize roof to rail spacing. Use 1 per L-foot. Service Condition 4
(very severe) zinc-plated welded steel. Includes 3/8" x 1-1/4"
bolt and lock washer for attaching L-foot.
Installer supplied materials
Lag screw
—Attaches L-foot or standoff to rafter. Determine
length based on pull-out values in Table 3 (page 7). If bolt
head is exposed to elements, use stainless steel. Under fl ash-
ings, zinc plated hardware is adequate.
Waterproof roofi ng sealant
appropriate to roofi ng material.
Flashing
—Use with standoffs only, 1 per standoff. Standoffs
are designed for easiest installation with most Oatey® 1-1/4"
to 1-1/2" No-Calk® fl ashings. Other appropriate fl ashings may
also be used.
Clamps for standing seam metal roof
—See “Frequently
Asked Questions . . .” (p. 12).
