SAFETY
General
You must understand and follow all applicable local, state, and federal
regulations and standards for building construction, electrical design, fire, 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 confirmed to be capable of handling the additional
weighted load of PV system components, including PV
modules, by a certified building specialist or engineer.
For your safety, do not attempt to work on a rooftop until
safety precautions have been identified 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 flat-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.
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 first 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, first 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 aect 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 fire resistance rating in accordance
with UL 1703 certification. The fire rating of this PV module is valid only when
mounted in the manner specified in the mechanical mounting instructions.
When PV modules are mounted on rooftops, the roof must have a fire resistant
covering suitable for this application. PV modules are electrical generating
devices that may aect the fire 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 fire in this event, PV modules should not be installed near
flammable liquids, gases, or locations with hazardous materials.
In the event of a fire, 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 fire, inform the fire crew about the particular hazards from the PV
system, and stay away from all elements of the PV system during and after a fire
until the necessary steps have been taken to make the PV system safe.
A.For cUL listed products - Class C fire rating. For UL listed products -The
modules with the specified construction in below table, when used with a Listed
mounting system that has been rated as a Class A System when installed with
type 1 and/or type 2 modules, is suitable to maintain the System Class A Fire
Rating.

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 aect 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.
Artificially 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 significantly 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.
ELECTRICAL INSTALLATION
Electrical Configuration
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 25°C 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 dierent electrical
characteristics must not be connected directly in series. The use of suitable
third-party electronic devices connected to PV modules may enable dierent
electrical connections and must be installed according to the manufacturer’s
specified 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 specified 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. In one and two-family
dwellings, PV source circuits and PV output circuits are permitted to have a
maximum system voltage up to 600 volts according to the NEC.
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 configurations so
long as the manufacturer’s instructions are followed.
Use field 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 qualified for direct current (DC)
wiring in PV systems. The minimum wire size should be 12 AWG.

damage of the cable and/or the module is avoided. Maintain a minimum cable
bending radius greater or equal than five times the cable diameter. Route
the cable in a way that the tensile stress on the conductor or connections is
prevented. For fixing, use appropriate means, such as sunlight resistant cable
ties and/or wire management clips specifically 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
Protect unplugged connectors against moisture, dust
and any environmental pollution. Only clean and dry
plugged connectors fulfill their ingress protection (IP)
class. Ensure that connector caps are hand tight before
connecting the modules. 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.
Connectors of dierent manufacturers must not be mated. If necessary the
connection of modules can be made by technical personnel after the connector
has been exchanged for one of the same manufacturer. Guarantee and warranty
claims are not aected by a professional exchange.
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;
replacing diodes inside the junction box is not permitted.
Equipment Grounding
The frame of the PV module, as well as any exposed non-current-carrying metal
parts of fixed 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 specific 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. A PV module with
exposed conductive parts is considered to be in compliance with UL 1703 only
when it is electrically grounded in accordance with the instructions presented
below and the requirements of the National Electrical Code.
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 dierence 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.
Where common grounding hardware (nuts, bolts, star washers, spilt-ring lock
washers, flat washers and the like) is used to attach a listed grounding/bonding
device, the attachment must be made in conformance with the grounding
device manufacturer’s instructions.

Option C: Racking Manufacturer Integrated
Grounding Methods
Yingli Solar PV modules can be grounded by bonding PV modules to a grounded
racking system. Integrated grounding methods must be certified to UL 1703 or
2703 for grounding PV modules and must be installed in accordance with the
specified instructions of their respective manufacturers.
A.Where common grounding hardware (nuts, bolts, star washers, spilt-ring lock
washers, flat washers and the like) is used to attach a listed grounding/bonding
device, the attachment must be made in conformance with the grounding
device manufacturer’s instructions.
B.Common hardware items such as nuts, bolts, star washers, lock washers
and the like have not been evaluated for electrical conductivity or for use
as grounding devices and should be used only for maintaining mechanical
connections and holding electrical grounding devices in the proper position
for electrical conductivity. Such devices, where supplied with the module and
evaluated through the requirements in UL 1703, may be used for grounding
connections in accordance with the instructions provided with the module.
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 dierence 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 fire class rating, the distance between the PV module
bottom surface and the roof surface shall be at least 2.48 inches (6.3 cm). This
spacing also allows air flow 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 PV module is considered to be in compliance with UL 1703 only when the
PV module is mounted in the manner specified by the mounting instructions PV
module below.
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 specific module series. The locations

INSTALLATION OF YGE-Z SERIES
ZEP COMPATIBLE MODULES
Yingli Solar oers the YGE-Z Series PV module which features a modified
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 please find “ YGE-Z Series Installation Supplement”.
The YGE-Z Series PV module warranty will become void if non-Zep-certified
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 qualified person.
The purpose of the PV system inspection is to ensure that all system components
are functioning properly. At a minimum, this inspection should confirm 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-reflective 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 aect 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.
