Installation guide solar modules 

 

 

V1 – April 2015 

14 - 19 

 

The obligatory position of the clips along the frame depends on which side of the module is used for the 

installation. 

Note  that  on  both  sides  of  the  module  the  pressure  clamps  always  should  be  mounted  in  a  symmetric 

position with respect to the center line for a proper load distribution.  

Clamps  must  be  installed  according  to  the  manufacturer’s  specific  instructions.  Do  not  apply  excessive 

pressure on the frame such that the frame deforms. MegaCell recommends a torque of approximately 10 

Newton meter [Nm], but refer to the clamp manufacturer for specific hardware and torque requirements. 

For a safe and effective installation of MegaCell framed modules, the lengths for the pressure clamps are 

strongly recommended is not less than 50 mm for 60 - 156 x 156 mm cell modules. 

The minimum recommended clamp thickness is 2,5 mm 

The clamps should have contact only with the module frame and, to avoid shadowing effects and possible 

damage, should not overlap onto or over the module glass. 

Do not install the modules with pressure clamps mounted out of the specified areas, otherwise the module 

mechanical resistance may be affected. 

Use of unauthorized laminate clamps will render the product and performance warranty void 

 

5.2

 

Frameless modules 

The  use  of  frameless  MegaCell  modules  requires  frameless  mounting  system  that  grabs  the  edge  of  the 

module with a pressure clamp that is lined with rubber pads (EPDM, etc). 

 The clamps must overlap from the edge of the module by at least 10mm but should avoid shading the cells 

in  the  module.  The  applied  torque  used  to  attach  the  clamps  to  the  module/racking  should  refer  to  the 

mechanical design standard for the specific bolt in use.  

For 4 point mounting, 4 mounting clamps should be located as described on paragraph 5.4  

 

Depending  on  local  snow  and  wind  conditions,  more  than  4  clamps  may  be  needed  to  ensure  that  the 

modules can withstand the expected load. For loads larger than 4000Pa (50psf), ensure that each clamp has 

a  minimum  length  of  120mm.  Do  not  use  clamps  with  a  length  smaller  than  80mm  unless  approved  by 

MegaCell. 

 

When installing modules in an array, please allow for a minimum lateral air gap of at least 10mm between 

the exposed edges of the adjacent modules to account for thermal expansion and contraction of PV system 

elements in the field. 

 

5.3

 

Frameless modules: continuous mounting (Carports, BIPV, etc.)  

For a continuous mounting system where the entire perimeter of the module is used, the mounting surface 

that contacts the module should:  

o

 

Be a rubber material (such as EPDM, etc.) on all surfaces making contact with the module.
