INSTALLATION INSTRUCTIONS -PHOTOVOLTAIC MODULES-
1. INSTALLATION 
  Mounting Using Clips:  
The PV modules can be mounted with clips (clamps) 
as defined in the following. Note that the mounting clips 
should meet the required dimensions as defined in the 
Figure1.  Note  that  the  CLIP CENTER  POSITION  (e) 
from the module corner should be located in the range 
as specified in the Annex. All clips 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 10 mm.  
 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 Annex. The module should be fastened with 
four (4) M8 bolts. Recommended torque is 12.5 Nm. 
2. ELECTRICAL INSTALLATION INSTRUCTION 
  Cable caracteristics:  
Conductor  size:  4.0  mm
2
,  Cable  type:  XLPE  cable 
(H1Z2Z2-K) 
Maximum DC voltage: 1.5 kV 
Ambient temperature: -40 °C to +90 °C 
Maximum conductor temperature: 120 °C 
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 overload.) 
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 overload.) 
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. 
3. WARNING 
Keep  all  PV  MODULES  and 
electriacal CONNECTORS clean & 
dry before installation. 
4. Disposal  
Dispose  PV modules  properly.  For 
Information  about  the  proper 
disposal,  contact  your  local 
recycling site. 
ELECTRICAL OUTPUT AND THERMAL CHARACTERISTICS 
Rated electrical characteristics are within ±10 percent of the indicated values of Voc, Isc and +5/-0 percent of Pmax (power 
measurement tolerance: ± 3 %), under STC (standard test conditions) (irradiance of 1000 W/m², AM 1.5 spectrum, and a cell 
temperature of 25 °C (77 °F)).

* 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. Accordingly, the values of Isc and Voc marked on this PV module should be multiplied by a factor 
of 1.25 when determining component voltage ratings, conductor capacities, 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 geeral user access and contact to insulated live parts is 
anticipated. 
FIRE RATING 
This PV module is rated as “Fire safety class C” according to 
IEC61730-2:2004 or UL790.
