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
