Mounting Methods

 

General Information

 

• Select  the  appropriate  orientation  to  maximize 

sunlight exposure. 

• In   order   to   prevent   water   from   entering   the 

junction box, which could present a safety hazard, 
module  should  not  be  mounted  such  that  the 
front/top glass faces downward. 

• Clearance  between  the solar  module  frames  and 

structures  such  as  roofs  or  ground  is  required  to 
prevent   wiring   damage   and   to   allow   air   to 
circulate  behind  the  solar  module.  The 
recommended  standoff  height  is  a  minimum  of 
100mm. 

• When  installed  on  a  roof,  the  solar  module  must 

be  mounted  over  a  fire-resistant  roof  covering 
rated for the application. The fire resistance of the 
solar module from LG Electronics is class C after 
ANSI/UL790. 

• The solar module is only IEC listed for use when 

its factory frame is fully intact. 

• Do not remove or alter the solar module frame. 
• Creating  additional  mounting  holes  may  damage 

the  solar  module  and  reduce  the  strength  of  the 
frame. 

•  A  6mm  gap  between  module  frames  should  be 

allowed to avoid tension from thermal expansion. 

• The solar module may be mounted using the 

following methods: (*Torque:8~12Nm ) 

• When installing modules in heavy snow areas, 

special care should be taken to install the 
modules in a manner that provides sufficient 
design strength while meeting local code 
requirements. 

 

Mounting by using frame bolts holes

 

•  Secure  the  solar  module  to  the  structure  using 

the factory mounting holes. 

• Four  M8   stainless   steel   bolts,  four  nuts,  four 

spring  washers,  and  eight  flat  washers  are 
recommended per solar module. 

• The  module  may  be  fastened  to  a  support  using 

both the outer and inner bolt holes of the frame. 

•  Each  module  should  be  securely  fastened  at  a 

minimum 4 points on two opposite sides. 

• Specific    information    on    the    solar    module 

dimensions  and  location  of  mounting  holes  is 
provided in ‘Product Specifications’. 

• Tighten  the  bolt  securely  using  this  combination. 

Place  spring  washer  between  Flat  washer  and 
Nut.

→ 

We recommend more than 40x40mm mounting rails.

 

 

Mounting by using clip or clamps

 

• The  module  may  be  fastened  to  a  support  using 

clips  or  clamps  on  both  the  long  edge  and  the 
short edge of the modules. 

• Specific information on location of clamping 

is provided in ‘Mechanical Installation Scene’ 
(Refer Appendix.). 

• The module frame must overlap more than 15mm.
