*NOTE:
1. The crossbeam is perpendicular to the long side.
This installation may cause the cell covered, so ZNSHINE
SOLAR does not recommend this installation for Framed
Bifacial double-glass.
2. Need two support rails below the PV module to make
sure the Mechanical load.
3. The load is an empirical value of a standard module
based on a standard installation mode, and the specific
information shall be consulted by ZNSHINE SOLAR.

B. Mounting with Single-axis Tracking System with 4-
φ
7*10mm mounting holes
Modules can be attached through the mounting holes 4-φ7*10mm on the back of the module frame, by fixing
the module to the support rails with bolts. The mounting details are shown in the following figures.
The frame of each module has 4-φ7*10mm mounting holes, ideally placed to optimize the load handling
capability, to secure the modules to supporting structure. 4 installation holes of 7*10 mm are used for Single-axis
tracking system installation, as shown in Figure 5

To maximize mounting longevity, ZNSHINE SOLAR strongly recommends the use of corrosion proof
(stainless steel) attachment hardware.
Secure the module in each mounting location with an M6 bolt and a flat washer, spring washer and nut and
tighten to a torque of 16~20 N.m(140-180lbf.in.).
The bolt should be made of stainless steel or the other anti-corrosion material.
Flat stainless steel gaskets with a minimum thickness of 1.5mm and an external diameter of 16- 20mm shall
be used in all parts of the components connected to the Single-axis tracking system.
