Mechanical installation
The TRIxxxBC-xB photovoltaic modules are designed for a maximum test load of
3.600 Pa (including a safety factor of 1,5) when installed on a mounting system
designed for this type of load. Make sure that the wind and snow load do not
exceed this limit at the installation site. In case of roof mounting, make sure that
it is able to support the load of the photovoltaic system. Assemble the
photovoltaic modules according to the procedures described below. The
photovoltaic modules can be fixed to the mounting system using the
appropriate clamps. The TRIxxxBC-xB photovoltaic modules can be mounted at
any angle.
Choose the orientation of the modules to ensure maximum exposure to the sun.
The ideal exposure is towards the south in the northern hemisphere and
towards the north in the southern hemisphere. In Central Europe the inclination
should be around 30 °, while in Southern Europe it should be slightly lower. The
inclination should preferably be not less than 10 ° - 15 ° because the self-
cleaning function of the surface of the modules would be compromised.
Make sure that the modules are not covered by shadows due to the presence of
antennas, chimneys, trees or other similar elements.

Electrical installation
Wiring
The TRIxxxBC-xB photovoltaic modules can be connected in series or in parallel
according to the electric power to be obtained. Use photovoltaic modules of the
same type in combined connection or in any case verify the electrotechnical
compatibility of the modules belonging to the same string / independent input
of the inverter.
Series connection
Do not exceed the maximum system voltage. Photovoltaic modules can be
connected in series to achieve a higher output voltage. Series connection is
preferable if the systems have no shadings. The series connection has the
following advantages:
• photovoltaic modules can be assembled easily and quickly;
• higher voltages make cross-sections of smaller cables possible;
• the higher voltages result in smaller currents and therefore lower power
losses.
Parallel connection
PV modules can be connected in parallel to achieve a higher output current.
Each string, or photovoltaic module in series, shall be fused before being
combined with other strings. For this purpose, the TRIxxxBC-xB modules are
equipped with bypass diodes located in the junction box. Comply with the
applicable regional and local regulations regarding fuse requirements and
limitations in the maximum number of PV modules for parallel connection. The
maximum number of photovoltaic modules for parallel connection without
additional precautions, such as fuses or blocking diodes, is one string of
modules. The number of strings is not limited if adequate precautions have been
taken to block the reverse current, such as fuses to protect the photovoltaic
module and the cable against overcurrent or blocking diodes for uneven string
voltage.
