mounted without continuous rails below them, the maximum allowable loading will be reduced and needs to be
subjected to review by ZNSHINE SOLAR.
Please ensure that the modules with the same color cells to be installed together.
A clearance of at least 115mm (recommended) is provided between modules and the surface of the wall or
roof.
The minimum clearance between two adjacent modules must not be less than 10mm.
The module frame drain holes cannot be blocked in any situation during installation or use.
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 M8 bolt and a flat washer, spring washer and nut and
tighten to a torque of 16~20 N.m(140-180lbf.in.). The tightening step is as follows :
a. Use torque wrench to tighten nut to target torque: 16~20N.m;
b. Nut loosen 90~180 degrees;
c. Finally tighten the nut to the target torque and reduce the torque attenuation.
All parts in contact with the modules should use flat stainless steel washers of minimum 1.8mm thickness
with an outer diameter of 20-24mm.(Except for Single-axis tracking system)
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.
The installation method listed below are for your reference only, the PV system installer or the trained
professionals should take the responsibility of the PV system design, mechanical load calculation, install,
maintenance and safety, ZNSHINE SOLAR will not supply the related material for system installation.
Tools: screwdriver, wrench, stainless steel screw/bolt, clamp, nut and spring washer, plain washer.
A. Mounting with Bolts 4-
φ
9*14mm mounting holes, (Applicable to framed Double-glass and framed
Bifacial double-glass)
Modules can be attached using the mounting holes 4-φ9*14mm 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 8-φ9*14mm mounting holes, ideally placed to optimize the load handling
capability, to secure the modules to the supporting structure. The middle four mounting holes are used for normal
installation, as shown in Figure 5-3. It is recommended that you put the PV module vertically when you use the
bolt to fix it, so that the module will not slide easily and use more safely.
