Solar Module Installation Manual
• Do not immerse modules in water or constantly expose modules to water (either
fresh or salt) (i.e. from fountains, sea spray).
• Exposing modules to salt (i.e. marine environments) and sulfur (i.e. sulfur sources,
volcanoes) risks module corrosion.
H. REQUIREMENTS FOR INSTALLATION
• Connect the quantity of modules that match the voltage specifications of the
inverters used in the system. Modules must not be connected together to create a
voltage higher than the permitted maximum system voltage, even under the worst
local temperature conditions.
• A maximum of two strings can be connected in parallel without using over‐current
protection device (fuses...) incorporated in series within each string. Three of more
strings can be connected in parallel only if an appropriate and certified over‐current
protection device is installed in series with each string.
• Modules with similar electrical performance should be connected in same series to
avoid or minimize mismatch effects in arrays.
• Cover the module surface (glass side) with an opaque material so that no light shines on
the glass surface and ensure that there is no electricity production from the module
before making any electrical connections.
• Be sure to disconnect Photovoltaic module from any other electrical sources like
batteries, inverters, electrical grid etc before working on the module.
• Ensure that only people qualified in handling electrical equipments are installing these
modules.
• Broken glass on the module is electrical safety hazard. Please replace the module
immediately in case you discover a broken module.
• Under some conditions the photovoltaic module produces electrical current /voltage
more than specified on the rating plate. Please take appropriate measures to size the
other equipments you intent to connect to this module.
• Please note there are no user serviceable parts inside the module and it is advised not
to disassemble the module.
• The front surface of the module is made from high transmission tempered/toughened
glass but also could break easily if it is not handled properly. The special textured
structure on the glass ensures high light absorption at low incidence angle. Please
protect this glass surface during transportation and handling.
• Please store the module in such a way that it does not fall off or come under falling
objects.
Solar Module Installation Manual
• Please do not allow children and unauthorized persons near the installation site.
• Do not install broken or damaged module(s).
• Before installing the modules on the building or any other structure make sure that
the installation meets the requirements of the local building codes and regulations.
• Be sure that the construction of the structure (Roof, facade etc.) where the modules
are being installed has enough strength.
• A special construction may be required for the modules mounted on roof to help
proper installation.
• Both roof construction and module installation should have effective fire resistant
materials.
• In order to cool the modules, a minimum clearance of about 100 mm must be
provided between the back of the modules and the roof.
Optimum orientation and tilt
Find out the optimum orientation and tilt of the PV modules for your region to
•
achieve the maximum annual yield. Generation of maximum power occurs when
sunlight shines perpendicularly onto the PV modules.
Reliable ventilation
• Sufficient clearance (at least 10 cm) between the module frame and the mounting
surface is required to allow for cooling air to circulate around the back of the
module. This also allows for condensation or moisture to dissipate.
Correct connection of plug connectors
Make sure that the connection is safe and tight. The plug connector should not
•
receive outer stress. The connector should only be used to connect the circuit. It
should never be used to turn the circuit on and off.
Use of suitable materials
• Use special solar cable and suitable plugs only (wiring should be placed in conduit
that is sunlight‐resistant or, if exposed, should be sunlight‐resistant) in accordance
with local fire, building and electrical code. Ensure that they are in perfect electrical
and mechanical condition.
• The permitted type of solar cable is single conductor, 4.0‐10 mm
wet rated, with proper insulation to Withstand the maximum possible system
open‐circuit voltage (such as TUV 2PfG1169 approved). The conductor material
should be copper only. Select a suitable conductor gauge to minimize voltage drop.
