Mounting the Solar Collectors
Using Gator Clamps
The beauty of the Gator Clamp installation is its simplic-
ity. It can be used on just about any type of roof or rack
installation.
For rack systems, asphalt shingle roofs or tile roofs, fol-
low these simple steps:
1. Snap a chalk line across the roof or rack where you
want the top edge of the collectors to be located. The
collectors should slope slightly down toward the feed
end of the array for proper drainage.
2. Locate the center of the first truss/rafter you plan to
start from and drill a pilot hole where the first lag screw
will penetrate the roof. After verifying the pilot hole
properly penetrated the structural wood truss or rafter,
measure and mark off the center-to-center truss dimen-
sions for the rest of the trusses being used. This as-
sumes trusses are located on 24” centers. Position the
first clamp on the chalk line six (6) inches in from the
top corner of the first collector. The first collector will be
the one that is connected to the feed line at the bottom
header.
3. Subsequent clamps should be spaced out evenly
along the chalk line every 24”. Each clamp can be
located anywhere along the top header to match up to
the spacing of the roof rafters as long as there is a 2”
space between the edge of the clamp and the ribs (See
“ribs” in Fig. 14, pg. 17) on the collector header that exist
every one foot. This allows for horizontal expansion and
contraction. For barrel tile roofs, each clamp needs to
be positioned so that it is centered on the top ridge of a
tile, still as close to 24” centers as possible.
4. Since normal horizontal expansion and contraction of
an array of collectors takes place every day as collec-
tors heat up and cool down, it is preferable to lock the
center of each array in place so that the expansion and
contraction takes place evenly to the left and right of this
center point. The center collector of an array may be
locked in place by locating the clamps on that collector
adjacent to the left and right of one of the header ribs.
(Fig. 4, pg. 11) these clamps should be attached using
two lag bolts as opposed to one. Do not use this proce-
dure more than once on any array of collectors.
5. Apply ample sealant to the bottom of the clamp over
the hole or holes where the anchor bolt will attach (be
generous with sealant). (Fig. 5-A, pg. 11) Position the
bottom portion of the clamp perpendicular to the chalk
line with the lower hole being placed right on the chalk
line. Lag the clamp to the roof through the lower hole
using a 1/4” x 4” S.S. lag bolt. (Fig. 5-B, pg. 11) For bar-
rel tile roofs, place four (4) 110BTS barrel tile spacers
underneath each clamp by inserting the four feet of the
barrel tile spacer into the four corners of the bottom of
the clamp. (Fig. 6, pg. 11)
