open circuit voltage, short circuit current, maximum system voltage, PV module size and weight
under standard test conditions.
b)
Series number: Each module has a unique bar code number, each bar code number has 20 letters and
numbers. The bar code is permanently encapsulated inside the module, as can be seen clearly from
the top right corner of the module. The bar code number allows you to trace information about the
module production process.
3.3 Module electrical performance parameters
The electrical performance parameters of the module were measured under standard test conditions
(irradiance of 1000 W / m², AM 1.5 spectra, ambient temperature of 25 ° C) with a test uncertainty of ± 3%.
The maximum system module voltage is 1500V. Refer to the following table for electrical performance
parameters.
4 Installation
4.1 General safety
4.1.1
Sunerg Solar’s modules have been evaluated by according to IEC61215 and IEC61730, application class
A, modules rated for use in this application class may be used in system operating at greater than 50V DC or
240W. The safety class of the module is Class II, the class of fire rating is Class C
（
According to the standard
is UL790
）
, and the maximum series fuse is 20A.
4.1.2
The installer should abide by the relevant local laws and regulations when installing module. It is need to
obtain the required certificates in advance when necessary, such as the building permit.
4.1.3
Installing solar photovoltaic systems require specialized skills and knowledge. Installation should be
performed only by qualified person. Installers should assume the risk of all injuries that might occur during
installation, such as electric shock.
4.1.4
Photovoltaic modules are designed for outdoor use. Modules may be mounted on ground, rooftops,
vehicles or boats. Proper design of support structures is the responsibility of the system designers or installers.
When modules are mounted on rooftops, fire-protection rating of the final structure should be considered, and
also the later maintenance. The rooftops and support structure for PV system should only be certified by
architectural experts or engineer, which have a formal complete structure analysis results.
4.1.5
For your safety, do not install the modules without safety precautions.
4.1.6
For your safety, do not install or handle the modules under wet or adverse environment, including but not
limited to strong wind, gusty wind, frosted roof surfaces, wet environment.
4.2 Electrical properties safety
4.2.1
When a module is exposed to sunlight or other light sources, a direct current is present inside the module,
and electrical contact with the module may result in an electrical shock hazard.
4.2.2
In order to avoid arc and electric shock, please do not disconnect electrical connections under load. Keep
all electrical connectors dry and clean, and ensure that they are in proper working condition. Do not insert
other metal objects into the connector, or in any other way.
4.2.3
Do not apply paint or adhesive to module surface. Do not wipe modules with corrosive chemicals.
4.2.4
Do not use mirrors or other magnifiers to focus sunlight on the modules. Do not expose the backside of
