same inverter channel.
• If solar modules (except for smart module) on the same installation are mounted at different angles or
orientations then energy production can normally be optimized by connecting the different orientations to
different inverters (or different MPPT if the inverter has more than one MPPT). Refer to inverter
manufacturers for further guidelines.
• According to Intertek-conducted IEC 61701:2011, salt mist corrosion testing of photovoltaic (PV), Trina
Solar modules can be safely installed in corrosive salt areas within proximity of the ocean or sulfurous areas.
• According to IEC62716:2013 “Ammonia corrosion testing of photovoltaic (PV) modules” and DLG Fokus
testing for ammonia resistance, Trina Solar modules can be safely installed in ammonia-heavy
environments, such as farm houses.
6.1 MOUNTING METHODS
PV modules can be mounted to the substructure 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 installation of the modules must ensure that:
• A clearance of at least 115mm(4.5in) (recommended) is provided between modules frame and the surface
of the wall or roof. If other mounting means are employed this may affect the UL Listing or the fire class
ratings.
• The minimum distance between two modules is 10mm(0.4in).
• The mounting method does not block the module 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 structures.
*NOTE: The drain holes cannot be blocked in any situation during installation or use.
A. Mounting with Bolts
• The frame of each module has 4-φ9*14mm mounting holes, ideally placed to optimize the load
handling capability, to secure the modules to supporting structure.
• To maximize mounting longevity, Trina Solar strongly recommends the use of corrosion proof
(stainless steel) fixings
• Secure the module in each fixing location with an M8 bolt and a flat washer, spring washer and nut as
shown in Figure 1 and tighten to a torque of 16~20 N.m(140-180lbf.in.).
• All parts in contact with the frame should use flat stainless steel washers of minimum 1.8mm thickness
with an outer diameter of 20-24mm(0.79-0.94in).
