SAFETY
General
You must understand and follow all applicable local, state, and federal
regulations and standards for building construction, electrical design,
re, and safety, and must check with local authorities to determine
applicable permitting requirements before attempting to install or
maintain PV modules.
Rooftop PV systems should only be installed on
dwellings that have been formally analyzed for
structural integrity, and conrmed to be capable of
handling the additional weighted load of PV system
components, including PV modules, by a certied
building specialist or engineer.
For your safety, do not attempt to work on a rooftop until safety
precautions have been identied and taken, including without limitation
fall protection measures, ladders or stairways, and personal protective
equipment (PPE).
For your safety, do not install or handle PV modules under adverse
conditions, including without limitation strong or gusty winds, and wet or
frosted roof surfaces.
The at-plate PV module construction consists of a laminated assembly
of solar cells encapsulated within an insulating material with a rigid glass
surface and an insulated substrate. The laminated assembly is supported
by an aluminum frame that is also used for mounting the module. See
Figure 1 for an illustration of the PV module components.
Figure 1: Module components and cross-section of the laminated assembly
Electrical
PV modules can produce current and voltage when
exposed to light of any intensity. Electrical current
increases with higher light intensity. DC voltage of
30 Volts or higher is potentially lethal. Contacting the
live circuitry of a PV system operating under light can
result in lethal electric shock.

Installation and User Manual
Revision Date March 1, 2012 | Applicable for products in the United States and Canada.

Yingli Solar PV Modules, Installation and User Manual / page 2
De-energize PV modules by removing them entirely from light or by
covering their front surface with an opaque material. Regard the safety
regulations for live electrical equipment when working with modules that
are exposed to any light. Use Insulated tools and do not wear metallic
jewelry while working with PV modules.
In order to avoid arcing and electrical shock, do not disconnect electrical
connections under load. Faulty connections can also result in arcing and
electrical shock. Keep connectors dry and clean, and ensure that they
are in proper working condition. Never insert metallic objects into the
connectors, or modify them in any way in order to secure an electrical
connection.
Do not touch or handle PV modules with broken glass, separated frames
or a damaged backsheet unless the PV modules are rst disconnected
and you are wearing proper PPE. Avoid handling PV modules when they
are wet unless cleaning the PV modules as directed in this manual. Never
touch electrical connections that are wet without protecting yourself with
insulated gloves.
Transport and Handling
Yingli Solar PV modules must be transported in the supplied packaging
only and kept in the packaging until they are ready to be installed.
Protect pallets against movement and exposure to damage during
transportation. Secure pallets from falling over. Do not exceed the
maximum height of pallets to be stacked, as indicated on the pallet
packaging. Store pallets in a cool and dry location until the PV modules
are ready to be unpackaged.
Figure 2: Pallet of PV modules
Yingli Solar PV modules are heavy, and should be handled with care.
PV modules shall be handled at the frame; never use the junction box
or cables as a grip. Do not exert mechanical stress on the cables. Never
step on PV modules or drop or place heavy objects on them. Be careful
when placing PV modules on hard surfaces, and secure them from falling.
Broken glass can result in personal injury. PV modules with broken glass
cannot be repaired and must not be used. Broken or damaged PV
modules must be handled carefully and disposed of properly.
For unpacking PV modules from the Yingli Solar supplied packaging,
rst remove the pallet lid (after removing securing straps, if provided).
Remove PV modules one at a time by sliding them up the channel in
the package (see Figure 3). You may need to secure the remaining PV
modules in the pallet packaging to prevent them from falling over.
Figure 3: Removing PV modules from a pallet
Check PV modules for damage due to transportation before they
are installed; do not install damaged modules. Contact the company
you purchased the Yingli Solar PV modules from in order to obtain
information on making claims for defective PV modules.
PV module surfaces are susceptible to damage that could affect the
performance or safety of the PV module; do not damage or scratch
the PV module surfaces, and do not apply paint or adhesive to any of
the surfaces, including the frame. For your safety, do not disassemble
or modify Yingli Solar PV modules in any way. Doing so may degrade
performance or cause irreparable damage and will void any applicable
warranties.
If it is necessary to store PV modules prior to installation, the PV modules
should remain inside the packaging and protected from exposure that
could compromise the durability of the packaging.
Fire
Yingli Solar PV Modules have a Class C re resistance rating in
accordance with UL 1703 certication. When PV modules are mounted
on rooftops, the roof must have a re resistant covering suitable for this
application. PV modules are electrical generating devices that may affect
the re safety of a building.
The use of improper installation methods and/or defective parts may
result in the unexpected occurrence of an electrical arc during operation.
In order to mitigate the risk of re in this event, PV modules should not
be installed near ammable liquids, gases, or locations with hazardous
materials.
In the event of a re, PV modules may continue to produce a dangerous
voltage, even if they have been disconnected from the inverter, have
been partly or entirely destroyed, or the system wiring has been
compromised or destroyed. In the event of re, inform the re crew
about the particular hazards from the PV system, and stay away from
all elements of the PV system during and after a re until the necessary
steps have been taken to make the PV system safe.
APPLICATION INFORMATION
Application Restrictions
Yingli Solar PV modules must be mounted on appropriate mounting
structures positioned on suitable buildings, the ground, or other
structures suitable for PV modules (e.g. carports, building facades or PV
trackers). PV modules must not be mounted on moving vehicles of any
kind. Yingli Solar PV modules must not be installed in locations where
they could be submerged in water.
Yingli Solar PV modules must not be sited in locations where aggressive
substances such as salt or salt-water, or any other type of corrosive
agent, could affect the safety and/or performance of the PV modules.
Although Yingli Solar PV modules have passed the IEC 61701 salt-
mist corrosion test with a salt concentration of 5% by weight, galvanic
corrosion can occur between the aluminum frame of the PV module
and mounting or grounding hardware if such hardware is comprised of
dissimilar metals. Yingli Solar recommends that only stainless steel and
aluminum metal directly contact PV modules in seaside installations to
limit corrosion.
Articially concentrated light must not be directed on Yingli Solar PV
modules.
Design Recommendations
Yingli Solar recommends that PV modules be mounted at a minimum tilt
angle of 10 degrees to allow for proper self-cleaning from normal rain
showers.
Partial or complete shading of a PV module or modules can signicantly
reduce system performance. Yingli Solar recommends minimizing the
amount of shade throughout the year to increase the amount of energy
produced by the PV modules.
Lightning protection is recommended for PV systems that are to be
installed in locations with high probability of lightning strikes.

Yingli Solar PV Modules, Installation and User Manual / page 3
ELECTRICAL INSTALLATION
Electrical Conguration
Under normal conditions, a photovoltaic module is likely to experience
conditions that produce more current and/or voltage than reported
at Standard Test Conditions (STC: 1000 W/m2, AM 1.5, and 25ºC cell
temperature). As required by the US National Electric Code (NEC), the
short-circuit current (ISC) should be multiplied by a factor of 1.25 and the
open-circuit voltage (VOC) should be multiplied by a factor of up to 1.25
based on the lowest ambient temperature recorded for the installation
location when determining component voltage ratings, conductor
current ratings, fuse sizes, and size of controls connected to the PV
output. Follow Section 690.7 in the (NEC) to determine the adjusted
system voltage value.
Refer to Section 690.8 of the NEC for an additional multiplying factor of
125 percent (80 percent de-rating) which may be applicable for sizing
fuses and conductors.
Voltages are additive when PV modules are connected directly in series,
and module currents are additive when PV modules are connected
directly in parallel, as illustrated in Figure 4. PV modules with different
electrical characteristics must not be connected directly in series. The use
of suitable third-party electronic devices connected to PV modules may
enable different electrical connections and must be installed according
to the manufacturer’s specied instructions.
Figure 4: Electrical diagrams of series and parallel wiring
The maximum number of PV modules that can be connected in a series
string must be calculated in accordance with applicable regulations in
such a way that the specied maximum system voltage of the PV module
and all other electrical DC components will not be exceeded in open-
circuit operation at the lowest temperature expected at the PV system
location.
An appropriately rated overcurrent protection device must be used when
the reverse current could exceed the value of the maximum fuse rating
of the module. An overcurrent protection device is required for each
series string if more than two series strings are connected in parallel.
Cables and Wiring
Yingli PV modules are provided with two (2) stranded, sunlight resistant
output cables that are terminated with PV connectors ready for
most installations. The positive (+) terminal has a female connector
while the negative (-) terminal has a male connector. The module
wiring is intended for series connections (i.e. female (+) to male (-)
interconnections), but can also be used to connect suitable third-party
electrical devices that may have alternative wiring congurations so long
as the manufacturer’s instructions are followed.
Use eld wiring with suitable cross-sectional areas that are approved for
use at the maximum short-circuit current of the PV module. Yingli Solar
recommends installers use only sunlight resistant cables qualied for
direct current (DC) wiring in PV systems. The minimum wire size should
be 12 AWG.
Table 1: Required minimum eld wiring specications
Cables should be xed to the mounting structure in such a way that
mechanical damage of the cable and/or the module is avoided. Do not
apply stress to the cables. For xing, use appropriate means, such as
sunlight resistant cable ties and/or wire management clips specically
designed to attach to the PV module frame. While the cables are
sunlight resistant and waterproof, where possible, avoid direct sunlight
exposure and water immersion of the cables.
Connectors
Keep connectors dry and clean, and ensure that
connector caps are hand tight. Do not attempt
making an electrical connection with wet, soiled, or
otherwise faulty connectors. Avoid sunlight exposure
and water immersion of the connectors. Avoid
connectors resting on the ground or roof surface.
Faulty connections can result in arcs and electrical shock. Check that all
electrical connections are securely fastened. Make sure that all locking
connectors are fully engaged and locked.
Figure 5: Series interconnection of a male (-) and female (+) connector
The junction boxes used with Yingli Solar PV modules contain bypass
diodes wired in parallel with the PV cell strings. In the case of partial
shading, the diodes bypass the current generated by the non-shaded
cells, thereby limiting module heating and performance losses. Bypass
diodes are not overcurrent protection devices.
Bypass diodes divert current from the cell strings in the event of partial
shading. See Figure 6 for a diagram showing how the cell strings are
electrically connected with the diodes.
Figure 6: Electrical circuitry of cells and bypass diodes
In the event of a known or suspected diode failure, installers or
maintenance providers should contact the company the PV modules
were purchased from. Never attempt to open the junction box of a Yingli
Solar PV module yourself.

Equipment Grounding
The frame of the PV module, as well as any exposed non-current-carrying
metal parts of xed equipment that are able to become energized by the
PV system, must be connected to the equipment grounding conductor
in order to prevent electrical shock. Refer to section 250 of the NEC for
specic instructions on grounding. Even when applicable regulations,
code requirements, and standards do not require safety-related
grounding, Yingli Solar recommends grounding all PV module frames in
order to ensure the voltage between electrically conductive equipment
and earth ground is zero in all circumstances.
Proper equipment grounding is achieved by bonding all exposed non-
current-carrying metal equipment continuously to one another using an
appropriately sized equipment grounding conductor (EGC) or racking
system that can be used for integrated grounding (see Option C in
Grounding Methods below).
Yingli Solar PV modules employ a coated aluminum frame for corrosion
resistance. In order to properly ground the module frame, the coating
must be penetrated.
Grounding wire use copper wire with minimum 12 AWG insulated for a
minimum 90 ºC.
The potential for corrosion due to the electrochemical action between
dissimilar metals in contact is minimized if the electrochemical voltage
potential between the dissimilar metals is low. The grounding method
must not result in the direct contact of dissimilar metals with the
aluminum frame of the PV module that will result in galvanic corrosion.
An addendum to UL 1703 recommends metal combinations not exceed
an electrochemical potential difference of 0.5 Volts.
The frame rails have pre-drilled holes marked with a grounding sign,
as illustrated in Figure 7. These holes should be used for grounding
purposes and must not be used for mounting the PV modules. Do not
drill additional holes into the frame rails.

MECHANICAL INSTALLATION
Mounting structures and other mechanical parts must be designed and
approved to withstand the design wind and snow loads applicable for a
particular site. Yingli Solar PV modules must not be subjected to forces
from the substructure, including forces caused by thermal expansion.
The mounting method must not result in the direct contact of dissimilar
metals with the aluminum frame of the PV module that will result
in galvanic corrosion. An addendum to UL 1703 recommends metal
combinations not exceed an electrochemical potential difference of
0.5 Volts.
Yingli Solar PV modules can be mounted in landscape or portrait
orientation, as illustrated in Figure 10, provided that the mounting method
follows one of the acceptable methods listed below.
Figure 10: Landscape and portrait mounting
In order to maintain the re class rating, the distance between the PV
module front surface (glass) and the roof surface shall be at least 4
inches (10 cm). This spacing also allows air ow to cool the PV module.
Install PV modules with a minimum spacing of 0.4 inches (1 cm) between
neighboring frames to allow for thermal expansion.
Mounting Methods
The following mounting methods are available:
Option A: Bolts or clamps
Refer to the Module Supplement at the end of this manual to determine
how many connection points are required for a specic module series.
The locations of mounting holes and clamp tolerances are illustrated
in the drawings located in the Module Supplement. Do not modify the
existing mounting holes or drill new holes.
• Bolts: Modules must be mounted using the mounting holes located on
the rear side of the long frame parts using ¼ inch stainless steel bolts,
nuts, and washers. Refer to the racking manufacturer for specic torque
requirements. This mounting method has been tested for a maximum
static load of 50 psf (2400 Pa) in both the positive and negative
directions.
Figure 11: Detail of a bolt mounting attachment
• Top-down Clamps: Third-party clamps that have been designed for
PV mounting structures are an approved mounting attachment method
for Yingli Solar PV modules. Modules must be fastened using clamps
applied to the top side of the long frame parts. A clamp holds two
modules except for the clamps at the beginning and end of a module
row. The centerline of the clamps must be in line with the mounting
hole positions plus or minus a distance of two (2) inches (50mm).
Clamps must be installed according to the manufacturer’s specied
instructions with minimum bolt size of 1/4 inches. Do not apply
excessive pressure on the frame such that the frame deforms. Refer to
the clamp manufacturer for specic hardware and torque requirements.
This mounting method has been tested for a maximum static load of
50 psf (2400 Pa) in both the positive and negative directions.
Figure 12: Detail of a top-down clamp mounting attachment
Option B: PanelClaw™ Attachment System
Attachment with the PanelClaw system is permitted for Yingli Solar
PV modules listed in the Module Supplement. Support structures
manufactured by PanelClaw, Inc. employ a special clamp, or “claw” (Part
Number: 500-0005) designed to attach to the ange of the PV module at
each of the four corners, on the two short frame members.
Figure 13: Detail of claw placement
For proper attachment, place a claw over the PV module frame ange at
each of the four designated locations and tighten the stainless steel 3/8-
16 x 1.25” hex head cap screw to a torque pressure between 18 ft∙lbf
(24.4 N∙m) and 20 ft∙lbf (27.1 N∙m). Ensure that the claws are ush with
both the long and short lengths of the PV module ange. This mounting
method has been tested for a maximum static load of 50 psf (2400 Pa) in
both the positive and negative directions.

INSTALLATION OF YGE-Z SERIES
ZEP COMPATIBLE MODULES
Yingli Solar offers the YGE-Z Series PV module which features a
modied aluminum frame that is compatible with mounting and
grounding hardware manufactured by Zep Solar. Refer to the
‘YGE-Z Series Installation Supplement’ for installation information.
Detailed design and installation information of Zep Solar’s mounting
systems can be found at http://www.zepsolar.com/resources.html.
The YGE-Z Series PV module warranty will become void if
non-Zep-certied hardware is attached inside the Zep Groove of
the module frame.
YGE-Z Series PV modules are also compatible with the mounting
and grounding methods included in this manual.
MAINTENANCE
Yingli Solar recommends that PV systems be periodically inspected by
the installer, or other qualied person.
The purpose of the PV system inspection is to ensure that all system
components are functioning properly. At a minimum, this inspection
should conrm the following:
– All cables and connector attachments are undamaged
and properly secured
– No sharp objects are in contact with the PV module surfaces
– PV modules are not shaded by unwanted obstacles
and/or foreign material
– Mounting and grounding components are tightly secured
with no corrosion
Defects should be addressed immediately.
Cleaning
Over time, dirt and dust can accumulate on the glass surface of the
module, reducing its power output. Yingli Solar recommends periodic
cleaning of PV modules to ensure maximum power output, especially in
regions with low precipitation.
In order to reduce the potential for electrical and thermal shock, Yingli
Solar recommends cleaning PV modules during early morning or late
afternoon hours when solar radiation is low and the modules are cooler,
especially in regions with hotter temperatures.
Never attempt to clean a PV module with broken glass or other signs of
exposed wiring, as this presents a shock hazard.
Clean the glass surface of the PV modules with a soft brush using soft,
clean water with a recommended pressure less than 100psi (690kPa),
which is typical of most municipal water systems. Water with high
mineral content may leave deposits on the glass surface and is not
recommended.
Yingli Solar PV modules may contain a hydrophobic anti-reective
coating on the glass surface to enhance power output and reduce dirt
and dust buildup. In order to avoid module damage, do not clean PV
modules with a power washer or pressure washer. Do not use steam or
corrosive chemicals to facilitate the cleaning of modules. Do not use
aggressive tools or abrasive materials that could scratch or damage the
glass surface. Failure to comply with these requirements may adversely
affect the PV module performance.
Yingli Solar PV modules are designed to withstand high snow loads.
However, if removing snow is desired to enhance production, use a brush
to gently remove snow. Do not try to remove frozen snow or ice from PV
modules.
DECOMMISSIONING
The dismantling of PV systems must be performed with the same
care and safety precautions used during the initial installation. The PV
system can generate hazardous voltage even after the system has been
disconnected. Follow safety regulations for working with live electrical
equipment.
