MOUNTING INSTRUCTIONS
MOUNTING METHODS
-PV modules can be mounted to the subst-
ructure using either corrosion-proof M8 bolts
placed through the mounting holes on the rear
of the module or specially designed module
clamps.
-Regardless of the fixing method the final instal-
lation of the modules must ensure that:
-A clearance of at least 115mm is provided
between modules frame and the surface of the
wall or roof.
-The minimum distance between two modules
is 10 mm.
-The mounting method does not block the mo-
dule drainage holes.
-Panels are not subjected to wind or snow loads
exceeding the maximum permissible loads,
and are not subject to excessive forces due to
the thermal expansion of the support structu-
res.
MOUNTING WITH BOLTS
-The frame of each module has 8 x φ9mm
mounting holes, ideally placed to optimize the
load handling capability, to secure the modules
to supporting structure.
-To maximize mounting longevity, Taurus Reno-
vables Solar strongly recommends the use of
corrosion proof (stainless steel) fixings
-Secure the module in each fixing location with
an M8mm bolt and a flat washer, spring washer
and nut as shown in Figure 1 and tighten to a
torque of 16 Nm.

MOUNTING WITH CLAMPS
-Taurus Renovables Solar has tested its mo-
dules with a number of clamps from different
manufacturers and recommends the use of
clamps which have an EPDM or similar insu-
lating washer, fixing bolt of at least M6. The
clamp must overlap the module frame by at
least 7mm but no more than 10 mm.
-Use at minimum 4 clamps to fix modules on the
mounting rails.
-Modules clamps should not come into contact
with the front glass and must not deform the
frame.
-Be sure to avoid shadowing effects from the
module clamps.
-The module frame is not to be modified under
any circumstances.
-When choosing this type of clamp-mounting
method, use at least four clamps on each
module, two clamps should be attached on
each long sides of the module (for portrait
orientation) and each short sides of the module
(for landscape orientation). Depending on local
wind and snow loads, additional clamps may
be required to ensure that modules can bear
the load.
-Applied torque should refer to mechanical
design standard according to the bolt customer
is using, ex:M6 is 8N*M;M8 is 16N*M.
-Fig. 3
-Other mounting configurations can be used
however, failure to comply with the above
recommendations will result in a lowering of
the load handling (snow/wind load) capabilities
below the product specification 5400/2400Pa
and product failure as a result of an overload
situation will not be covered by the guarantee.
GROUNDING
-All module frames and mounting racks must be
properly grounded in accordance with approp-
riate respective National Electrical Code.
-Proper grounding is achieved by bonding
the module frame(s) and all metallic structu-
ral members together continuously using a
suitable grounding conductor. The grounding
conductor or strap may be copper, copper al-
loy, or any other material acceptable for use as
an electrical conductor per respective National
Electrical Codes. The grounding conductor
must then make a connection to earth using a
suitable earth ground electrode.
-Taurus Renovables Solar modules can be
installed with the use of third party listed
grounding devices for grounding the metallic
frames of PV modules. The devices have to
be installed in accordance with the grounding
device manufacturer’s specified instructions.
-Taurus Renovables Solar recommends using
the following grounding ways
-Using Schleter for grounding. Connecting mo-
dules to the support structure according to the
picture below. (Grounding accessories need
pass the UL467 standard test.)
-Fig. 4
-Recommended torque is 20.5Nm
