INSTALLATION INSTRUCTIONS -PHOTOVOLTAIC MODULES-
1. INSTALLATION
Mounting Using Clamps:
The PV modules can be mounted with clamps (clips) as defined in the
following. Note that the mounting clamps should meet the required
dimensions as defined in the Figure1. Note that the CLAMP CENTER
POSITION (e) from the module corner should be located in the range as
specified in the Annex. All clamps shall hold the module frame completely
within their width. Please be aware that the module under heavy load would
get serious deflection which could cause cell cracks that affects power
degradation. The PV module must be supported on the array system and must
overlap the array rail by at least 10mm.
Mounting Using Frame Bolt Holes:
The modules may be fastened to a support using the bolt holes in the
bottom of the frames at any of locations shown in the Annex. The module
should be fastened with four (4) or six (6) M8 bolts. Recommended torque is
12.5 Nm.

* The maximum series number of modules depends on the local conditions. These values are calculated under the condition of Voc at -40 °C.
Under normal conditions, a PV module is likely to experience conditions that produce more current and/or voltage than reported
at standard test conditions. Please consider the additional gain from the back side of the PV module compared to the power of
the front side at the standard test condition. It depends on mounting (structure, height, tilt angle etc.) and albedo of the ground.
Accordingly, the values of Isc and Voc marked on this PV module should be multiplied by a factor of 1.25, taking into account the
estimated power gain (i.e specified in Table-1), when determining component voltage ratings, conductor current ratings, fuse sizes
and size of controls connected to the PV module output.The PV module has been qualified in an environmental temperature range
of -40 °C to +40 °C and up to 100 % relative humidity as well as rain, and the altitude up to 2,000 m in accordance with IEC61730.
Class for protection against electric shock
This PV module is classified as "Class Ⅱ " according to
IEC61730. These PV modules are intended for installation
where general user access and contact to insulated live parts is
anticipated.

PV module configuration (Recommend)
# Maximum series configuration: please refer to Table 1
# Maximum parallel configuration: (Parallel connection of each
string shall be conducted with following two options. Any other
parallel connections are prohibited.)
a) Case of using the diodes; 1 diode per maximum 2 parallel
strings (Connect a diode or more in series for every string or
every 2 parallel strings for protection of PV module from
reverse current over load.)
b) Case of using the fuses; 1 fuse per every string (Connect a
fuse for every single string for protection of PV module from
reverse current over load.)
Connection cables requirement
The PV module shall be mated to the same connectors;
Type: C1 （System voltage 1,500 V）
Brand: Solargiga Energy Holdings Limited
In case connectors will be replaced by qualified personnel
according the mounting instructions of the manufacturer of the
new connectors, the guarantees on the module itself, will remain
valid according the applicable terms.
