4.0 UNPACKING AND STORAGE

Precautions and General Safety
·Store modules in a dry and ventilated room .
·Do not allow children and unauthorized persons near the installation site or storage area of modules.
·Do not transport modules in an upright position.
·Unpacking module pallet with care and follow the unpacking steps marked on the pallet. Be careful when unpacking,
transporting and storing the modules.
·Do not carry a module by its wires or junction box. Carry a module by its frame with two or more people.
·Do not place modules on top of each other.
·Do not place excessive loads on the module or twist the module frame.
·Do not bow modules under their own weight.
·Do not stand, step, walk and/or jump on the module.
·Do not drop or place objects on the modules (such as tools.)
·Do not mark the modules with sharp instrument. Particular attention should be taken to avoid module backsheet to
come in contact with sharp objects, as scratches may directly affect product safety.
·Do not leave a module unsupported or unsecured.
·Do not change the wiring of bypass diodes.
·Keep all electrical contacts clean and dry.

5.0 MODULE INSTALLATION

Precautions and General Safety
· Before installing modules, contact the appropriate authorities for site, installation and inspection
Diode type
· Check applicable building codes to ensure that the construction or structure (roof, facade, support,
· When installing the modules, please ensure the assembly is mounted over a fire resistant roof
· CAUTION: In any case DO NOT STAND OR STEP on the modules, as localized high loads may
Environmental conditions
· The module is intended for use in general open climates, as defined in IEC 60721-2-1: Classification of
Schottky
environmental conditions Part 2-1: Environmental conditions appearing in nature - temperature and humidity.
diodes
· Do not install modules near naked flames or flammable materials.
· Do not expose modules to artificially concentrated light sources.
· 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.
Requirements of installation
· Ensure that the module meets the technical requirements of the system as a whole.
· Ensure that other systems components do not exert damaging mechanical or electrical influences on the modules.
· Modules can be wired in a series to increase voltage or in parallel to increase current. To connect in series, connect
cables from the positive terminal of one module to the negative terminal of the next module. To connect in parallel,
connect cables from the positive terminal of one module to the positive terminal on the next module.
· Quantity of bypass diodes provided can vary depending on model series.
· 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.
· Similar electrical performance modules should be connected in the same series to avoid or minimize mismatch
effects in arrays.
· To minimize risk in the event of an indirect lightning strike, avoid forming loops when designing the system.
· The recommended maximum series fuse rating is tabulated in annex.
· Modules should be firmly fixed in place in a manner suitable to withstand all expected loads, including wind and
snow loads. A minimum clearance of 6.5 mm (1/4 of an inch) or more between modules is required to allow for thermal
expansion of the frames.
· Small openings for water draining on the underside of the module should not be blocked after mounting.
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.
Avoid shading
· Even the slightest partial shading (e.g., from dirt deposits) will cause a reduction in yield. A module is considered
"shadow-free" if it is unobstructed across its entire surface for the whole year. Even on the shortest day of the year,
unobstructed sunlight can reach the module.
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.

induce severe micro-cracks at the cell level, which in turn may compromise module reliability. Failure
to comply with above caution will void Canadian Solar Inc warranty.
