Mounting   

● 

Each module must be securely fastened at a minimum of 8 points(7mm×11.5mm). The frame has been stress 

tested for mounting on the long sides. Its short sides must not secure the module.   

● 

We recommend using a torque wrench for installation. The tightening torque(using stainless steel M6 bolts 

Stainless steel washer and Stainless steel M6 nut ) should be around 15-20Nm.Use the existing holes to secure 

the module and do not drill additional holes(doing so would void the warranty).Use appropriate 

corrosion-proof fastening material.   

● 

Clearance between the module frame and mounting surface may be required to prevent the junction box from 

touching the surface, and to circulate cooling air around the back of the module. If the modules are to be 

installed on the roof or wall of a building, the standoff method or the rack method is recommended. 

Stand-off 

method

: The modules are supported parallel to the surface of the building wall or roof. Clearance between the 

module frames and surface of the wall or roof is required to prevent wiring damage and to allow air to 

circulate behind the module. The recommended stand-off height is 115mm. If other mounting means are 

employed, this may affect the Listing For Fire Class Ratings.

Installation of the rooftop

 

When  doing  installation  on  roof  and  building,  make  sure  that  the  modules  are  fastened.  This  will  prevent  them 

from falling down in extreme weather. 

Do comply the safety regulations and use appointed secure equipment. 

Make  sure  there  is  enough ventilation  at  the  back  of  solar  modules  to  help  ease  the  installation  and  prevent  the 

hydrometeor 

Make sure there is enough area between the installation planes and the back of the modules; minimum distance: 

50mm

Wiring   

● 

The modules use the

PV-RH701

 type junction box. This box, on the back side of the module, is weatherproof 

and is designed to be used with standard wiring or conduit connections. Wiring methods should be in 

accordance with the NEC (National Electrical Code). Bypass diodes and cable clamps are included with each
