INSTALLATION INSTRUCTIONS
SOL 27 PREMIUM S & W COLLECTORS - 230016 & 230017
4˝ minimum
Drill pilot holes
Mounting Frame Lightning Protection
1. Connect the mounting frame to the lighning protection
system using screws similar to those used for the collectors.
5 Mounting
Instructions
Select the collector mounting kit that is capable of providing
the required tilt and azimuth in a mounting location that
is not subject to excessive shading of the solar collectors.
The mounting kit must be securely attached to a structure
capable of supporting and maintaining its integrity under
the static and dynamic (e.g., high wind) loading conditions.
The type of mounting system that is best-suited to the
installation must be determined by the designer, and must
take into consideration the details of the roof, wall, or
ground on which the collectors are to be placed, the latitude
and orientation of the site, the space available for the
collectors, possible shading from nearby structures, other
rows of collectors, or vegetation, etc. The intended use of the
system should also be an important consideration.
For anchoring in concrete, use six M8 UPAT Multicones or SM
M10 anchors, both of stainless steel, per collector.
For anchoring in wood, use six wood screws in accordance
with DIN 571, at least 10 x 80, of stainless steel, per collector.
If multiple arrays of collectors are being installed on a
fl at roof, one behind another, the recommended spacing
between them should be:
At least 25 ft. (7.6 m) for vertical installations.
At least 14 ft. (4.0 m) for horizontal installations.
This spacing prevents excessive shading from adjacent rows
for latitudes of up to 50°. For latitudes signifi cantly higher
than 50°, multiple rows of collectors may not be practical
due to low sun altitude angles.
If installing in a high wind environment, 8 clamps per
collector should be used. In vertical installations, 4 clamps
per collector are supplied with the collector frames, so 4
additional clamps per collector should be added to the
equipment list for the installation.
For more information on the specifi cations about Stiebel
Eltron solar racking systems, consult the specifi c installation
manuals.
The 45° vertical mounting racks can develop signifi cant
pull-out forces under heavy wind conditions; therefore it is
important to take wind loads into account.
Wall Mounting
All of the Stiebel Eltron tilt racking systems can be mounted
on a wall just as easily as on a roof.
The type of roof or wall is a crucial factor in the choice of
fasteners. Remember to take the static and dynamic (live
load) forces into account.
5.1 Flush Mounting
One of the most common types of collector installs are
fl ush mounted arrays. Mounting in this way is the most
visually appealing and structurally sound. The collectors
are subjected to lower wind and snow loads when fl ush
mounted to a roof.
