5.4.2 Vertical 30° Mounting on a Wall
Mounting the vertical 30° system on a wall is not recommended.
5.4.3 Vertical 30° Mounting On A Pitched Roof
Procedures described above for mounting of collectors on a flat
roof apply to mounting on a pitched (sloped) roof, except for the
following:
1. The 30° mounting kits add 30° to an existing roof pitch, as shown
in table 5.2.9.
5.4.4 Vertical 60° Mounting on a Flat Roof
(Please review section 5.4.0)
1. Choose attachment site, allowing for subsequent pipe penetration.
2. Assemble 2 triangular trusses using the 65” rails (M-103), the 92”
rails (M-102), the 79” rails (M-105), the brackets (M-101), and the
55 mm bolts similar to the manner shown in Figure 5.4.1 with the
following change: the 92” rails should be reversed such that the
65” rail connects to the end with the holes closest, and the 79” rail
connects to the end with the holes further away. If desired, the 65”
rails can be cut to 46.5”.
3. Bolt the trusses to the cross braces connecting the bolts as shown
in Figure 5.2.2. The resulting assembly should look similar to Figure
5.2.3. The collector frames may then be bolted to the holes in the
92” rails using the 20 mm bolts. The collector frames, as well as the
number of trusses used, depends on the number of collectors being
installed (see Table 5.1). If multiple mounting frames are being set
up next to one another, use frame connector kits (SFC001, shown in
Figure 5.2.6) to join them, as shown in Figures 5.1.1, 5.2.7 and 5.2.8.
4. If installing two or more collectors, the triangle trusses with their
attached cross braces are to be positioned at the midpoint, behind
the collectors. With a 3 collector system the 3 triangular trusses
should be equidistant with 2 sets of cross braces interconnecting
them. The resulting assembly should then be centered to support the
R1/R2/SFC001 frame assembly as shown in Figure 5.1.1.
5. When installing four or five trusses, brace both end spans with
crossbraces, as shown in 5.2.8. For six or more trusses, cross-braces
should also be placed in an inside span.
6. Fasten the base of the flat-roof mounting racks to the solar roof
mount flashing kit (560105SQ). Remember to take the static and
dynamic (e.g., wind) loading into account for the roof structure.
Nominal distance is 36 1/2” between the front and back mounting
holes and 48” between the bases.
5.4.5 Vertical 60° Mounting on a Wall
Procedures described above for mounting of collectors on a flat roof
apply to wall mounting, except for the following:
1. Cross braces should be attached to the 65” (cut down to 46.5”)
rail at the base of the trusses rather than the ones at the rear (as
pictured in figure 5.4.5).
2. Fasten the rear 79” rail of the trusses to the wall using the mount-
ing holes in a suitible manner.
3. Low elevation mounting configurations may be prone to damage
from falling ice or nearby vehicles or other hazards. Appropriate
precautions should be taken to mitigate these hazards.
5.4.6 Vertical 60° Mounting On A Pitched Roof
Procedures described above for mounting of collectors on a flat
roof apply to mounting on a pitched (sloped) roof, except for the
following:
1. The 60° mounting kits add 60° to an existing roof pitch, as shown
in table 5.2.9. Roofs with pitches above 4-in-12 generally should not
use this mounting kit, as the resulting collector tilt angle will be too
steep for almost any location.
5.4.7 Vertical 45° Mounting on a Flat Roof
(Please review section 5.4.0)
1. Choose attachment site, allowing for subsequent pipe penetration.
2. Assemble 2 triangular trusses using the 65” rails (M-103), the 92”
rails (M-102), the 79” rails (M-105), the brackets (M-101), and the 55
mm bolts as shown in Figure 5.4.2. If desired, the 79” rails can be
cut to 65”.
3. Bolt the trusses to the cross braces connecting the bolts as shown
in Figure 5.2.2. The resulting assembly should look similar to Figure
5.2.3. The collector frames may then be bolted to the holes in the
92” rails using the 20 mm bolts. The collector frames, as well as the
number of trusses used, depends on the number of collectors being
installed (see Table 5.1). If multiple mounting frames are being set
up next to one another, use frame connector kits (SFC001, shown in
Figure 5.2.6) to join them, as shown in Figures 5.2.7 and 5.2.8.
4. If installing two or more collectors, the triangle trusses with their
attached cross braces are to be positioned at the midpoint, behind
the collectors. With a 3 collector system the 3 triangular trusses
should be equidistant with 2 sets of cross braces interconnecting
them. The resulting assembly should then be centered to support the
R1/R2/SFC001 frame assembly as shown in Figure 5.1.1.
5. When installing four or five trusses, brace both end spans with
crossbraces, as shown in 5.2.8. For six or more trusses, cross-braces
should also be placed in an inside span.
6. Fasten the base of the flat-roof mounting racks to the solar roof
mount flashing kit (560105SQ). Remember to take the static and
dynamic (e.g., wind) loading into account for the roof structure.
Nominal distance is 4’ 7” between the front and back mounting
holes and 48” between the bases.
