3.3 Mounting Methods
Please completelyread this chapter content, be familiar with all process and then start the installation. In addition,
prepare for all the scene before starting the installation.
Modules must be laid across the supporting bars（The supporting bars width should be 40~80mm）, Clamps
installed symmetrically as follows (Fig. a).

Fig. a 6-clamp installation
Each clamp comes with an M8 bolt, a spring washer, a flat washer and an M8 nut. Use six clamps on each
module, three clamps should be attached on each long side of the module. To fasten the module:
1. Mounting middle clamps and edge clamps, Fig. b and Fig. c for your reference. Complete set of fasteners are
M8 bolts. The choice of hex bolt and cuboid nut depend on the structure and size of the beam. If you choose C beam
or C type steel, using matched bolts and nuts.

4.Electrical Installation
We require that all wiring and electrical connections comply with the appropriate National Electrical Code.
4.1 The electrical characteristics are within ±10 percent of the indicated values of ISC, VOC, and Pmax under
standard test conditions (irradiance of 1000W/m2, AM 1.5 spectrum, and a cell temperature of 25°C (77°F)).
4.2 The maximum system voltage is 1500 V。
4.3 The number of PV modules in a series circuit should match with inverter’s technology parameters of voltage.
The series voltage of modules that connected together in a series circuit should not higher than the permitted
maximum system voltage under the worst local temperature conditions.
4.4 Under normal conditions, a photovoltaic module is likely to experience conditions that produce more current
and/or voltage than reported at standard test conditions. The requirements of the National Electrical Code (NEC) in
Middle clamp is made up of the bottom and
the top half two parts. The material are
aluminum alloy 6063 with lengths of 250
mm. Connect two parts with M8 bolts.
Clamp has four rubber strips of 2-3 mm
thickness (Suggest to use EPDM rubber)

Article 690 shall be followed to address these increased outputs. In installations not under the requirements of the
NEC, the values of ISC and VOC marked on this module should be multiplied by a factor of 1.25 when determining
component voltage ratings, conductor capacities, over current device ratings, and size of controls connected to the
PV output.
4.5 Each module (or series-connected string of modules) shall be provided with the maximum series overcurrent
protective device, specified as 15A for the 6 inch cell module series.
4.6 Use a special solar cable and plugs for installing the PV system and make sure that all connections are safe and
tight. The cable cross section size should be 4mm2(12AWG) and able to withstand the maximum possible system
open-circuit voltage.
4.7 Bypass diodes are included in module junction boxes to avoid decreased module performance in the event of
shade or shelter.
4.8 Please check the relevant product datasheet for the specific diodes of J-box.
5.Maintenance and Disposal
5.1 Regularly carry out a visual inspection for dirt, dust, bird dropping, leaves, and other detritus covering the
modules.
5.2 If there is a build-up of dirt or dust on the module surface, wash the module with clean water and a gentle
implement (a sponge). Never use chemicals on the surface of the module.
5.3 If snow is present, a soft-bristled brush with soft bristles may be used to clean the surface of the modules.
5.4 Don't use cold water to clean modules in higher temperature to prevent thermal shock damage on modules.
5.5 At least once a year, it is recommended to check the torque of terminal bolts and the general condition of
wiring. Also, check that mounting hardware is properly torqued.
5.6 Regular electrical and mechanical inspection by a licensed professional will keep the system safe and operating
at maximum efficiency.
