Each PV module is affixed with two kinds of labels, providing the following information:
a) Label: Describes the product name, PV module model, nominal power, rated voltage, rated current,
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 18 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 technical specifications for electrical performance
parameters.
4 Installation
4.1 General safety
4.1.1
Bluesun solar’s modules have been evaluated by according to IEC61215 and IEC61730, Protection Class
Ⅱ
, modules rated for use in this protection class may be used in system operating at greater than 50V DC or
240W. The class of fire rating is Class C
（
According to the standard is UL790
）
.
4.1.2
The maximum rating of a fuse connected in series with an array string is typically 20A, but the actual
module specific rating can be found on the product label and in the product datasheet.
4.1.3
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.
4.1.4
Installing solar 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.
4.1.5
PV 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.
4.1.6
For your safety, do not install the modules without safety precautions.
4.1.7
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.
