Electrical Installation

Before & After Installation

• Dirt build-up on the surface of the panel may cause

active solar cells to be shaded and electrical
performance to be impaired.

• Always keep the back surface of the panel free

from any foreign objects or structural elements
which could come into contact with the panel.

After Installation

• Plug in the connector tightly and ensure that the

wiring properly works.

• Conduct periodic inspection of the panels for

damage to front glass, back sheet, frame, junction
box, or external electrical connections.

• Check electrical connections for loose connections

and corrosion.

• Removal of dirt from the front glass can increase

output.

• Water, ethanol or a conventional glass cleanser

with a micro-fiber cloth can be used for regular
washing or rinsing of the front glass to remove
dust, dirt or other deposits.

• Aggressive and abrasive cleansers or chemicals

such as alkali chemicals including ammonia based
solution should not be used on cleaning the module.

• Always wear rubber gloves for electrical insulation

while maintaining, washing or cleaning panels.

• Deposits of foreign material on the frame surface

can be cleaned by using a wet sponge or cloth and
dried in air or by using a clean chamois.

• Perform the wiring work by connecting the

connector and wires to the stand away from the
roof or ground.

Before Installation

Please carefully read this manual before installation.
• Contact with electrically active parts of the panels,

such as terminals, may result in burns, sparks and
lethal shock whether the panel is connected or
disconnected.

• Panels produce voltage even when not connected

to an electrical circuit or load.

• Solar module installation and maintenance must be

performed by qualified and authorized installer.

• All installation instructions should be read and

understood before performing any installation.

• Do not twist, pull, or scratch the cable attached to

the solar module.

• Do not touch the solar module with bare hands.

Failure to comply may result in a serious burn or
injury.

• Do not drop the solar module or place weight on a

solar module.

• Do not disassemble the solar module.
• After installation or repair, check that the solar

module are operating properly.

• In the event that the currently used solar module or

parts have been replaced the newly replaced
module and parts must have the same model
name and parts as the previously installed solar
module.

• Secure all necessary permits and licenses to install

the solar modules

• Only qualified and authorized individuals are

permitted to treat electrical parts, when there is a
breakage, failure or damage of the product or
damage of the product.

• Do not use or install broken modules; Failure to

comply may result in fire, electric shock, and injury.

• Do not install the module horizontally. Failure to

comply may result in excess dirt or white
efflorescence (glass disease).

• Panels are not intended for use indoors or on

moving vehicles of any kind.

• Reflection from external environments such as

snow Reflection from external environments such
as snow, water or other surfaces may increase the
power generated by the panel.

• Industry standard rated specifications are made at

conditions of 1000W/m 2 irradiance and 25 °C
(77ºF) solar cell temperature. Colder temperatures
may substantially increase voltage and power.

• Keep the solar module and system away from

children at all times.

• Keep the module packed in the carton until the

time of installation.

• Keep flammable gasses away from the installation

site.

• Do not work alone. Please work as part of a team

of two or more people.

• Safety harness use is strongly recommended for

installation.

• Partial shadowing may substantially reduce panel

and system output.

• Care must be taken to avoid low tilt angles which

may cause dirt to buildup on the glass against the
frame edge.

Danger

• Avoid all electrical hazards when installing, wiring,

operating and maintaining all panels.

• Do not connect panels that have different electrical

properties or physical configurations in the same
system.

• Match the polarities of cables and terminals when

making the connections; failure to do so may result
in damage to the panel.

• The rating of the over-current device shall not

exceed the maximum series fuse rating marked on
the name plate.

• The panel contains factory installed bypass diodes

located inside the junction box.

• When installing the system, it is recommended to

install a lightning rod to protect the system.
