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,

includingwithoutlimitationstrongorgustywinds,andwetorfrostedroofsurfaces.

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 installation 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.

YINGLISOLAR.COM © Yingli Energy Development Company Limited

GB 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 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

the IEC 61730-2 certiﬁcation. 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.

APPLICATION INFORMATION

Application Restrictions

Yingli Solar PV modules must be mounted on appropriate installation 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 some types

of 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 installation 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.

High system voltages could be induced in the event of an indirect lightning

strike, which could cause damage to PV system components. The open area of

wire loops should be minimized, as shown in Figure 4, in order to reduce the risk

YINGLISOLAR.COM © Yingli Energy Development Company Limited

of lightning induced voltage surges.

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). 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.

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 5. 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 5: 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.

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 over current protection device and anti-reﬂection diode module

are required for each series string if more than two series strings are connected

in parallel.and reverse polarity is forbidden.

Cables and Wiring

Yingli Solar 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 4mm2.

Table 1: Required minimum ﬁeld wiring speciﬁcations

Testing Standard Wire Size Temperature Rating

Required Minimum Field Wiring EN 50618 4 mm2- 40ºC to + 90ºC

Cables should be ﬁxed to the installation structure in such a way that

mechanical damage of the cable and/or the module is avoided. Do not apply

stress to the cables. Do not bend cables to a bending radius of less than 40mm.

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

Keep connectors dry and clean, and 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.

Modules must not be interconnected using connectors from dierent

manufacturers and / or of dierent types. If modules having such dierent

connectors need to be interconnected, a qualiﬁed professional may replace

connectors according to the manufacturers’ speciﬁed instructions such that an

interconnection can be made with connectors from the same manufacturer and

the same type.

Figure 6: Series interconnection of a male (-) and female (+) connector

Bypass Diodes

The junction boxes used with Yingli Solar PV modules (not Smart Hot Spot Free

module) 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 7-1 for a diagram showing how the cell strings are electrically

connected with the diodes.

Every piece of cells from Yingli Smart Hot Spot Free module parallels a diode,

with a cell is covered by shade or occurs an excepion, the paralleled diode can

bypass this cell, thus avoid hot spot, and can retain the maximum power output.

Bypass diodes divert current from a cell in the event of partial shading, See

ﬁgure 7-2 for a diagram showing how the cells are electricallly connected with

the diodes.

Never attempt to open the junction box of a Yingli Solar PV module yourself.

PV Array Grounding

For optimal performance, Yingli Solar recommends that the negative pole of the

PV array be connected to ground.

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 (EGC) in order to

prevent electrical shock. 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 EGC or racking system that can be used for integrated grounding (see

Option B 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.

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 Standard 1703 “Flat Plate

Photovoltaic Modules and Panels” 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 8. These holes should be used for grounding purposes and

must not be used for installation the PV modules. Do not drill additional holes

into the frame rails.

Figure 8: Grounding hole detail

The following grounding methods are available:

Option A: Screw Assembly (see Figure 9)

1. The grounding screw must be installed on the designed grounding hole and

must be stainless steel screw.

2. The screw ﬁrst passes through the stainless steel ﬂat washers. The screw

rods pass through the grounding holes outwards, and then pass through

the stainless steel piercing washers, grounding terminal, stainless steel ﬂat

washers, and stainless steel spring washers in turn, and ﬁnally ﬁx them with

stainless steel backing nuts.

3. Tighten the backing nut to a torque of not less than 4 N∙m to ensure that the

backing nut can securely hold the screw.

4. Install piercing washers of appropriate size, and ensure that the protrusions of

the piercing washers reliably pierce the frame of the module.

Figure 9: Grounding screw assembly detail

Option B: 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 for grounding

PV modules and must be installed in accordance with the speciﬁed instructions

of their respective manufacturers.

Option C: Additional Third-party Grounding Devices

Yingli Solar PV modules can be grounded using third party grounding devices so

long as they are certiﬁed for grounding PV modules and the devices are installed

according to the manufacturer’s speciﬁed instructions.

MECHANICAL INSTALLATION

General

Yingli Solar PV Modules have been certiﬁed for a maximum static load on the

back of the module of up to 2400 Pa (i.e. wind load) and a maximum static load

on the front of the module of up to either 2400 Pa or 5400 Pa (i.e. wind and

snow load), depending on the module type (please refer to the data sheet for

this information).

Installation 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 installation 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 Standard 1703 “Flat Plate Photovoltaic Modules

and Panels” 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

installation method follows one of the acceptable methods listed below.

Figure 10: Landscape and portrait installation

In order to maintain the ﬁre class rating, the distance between the PV module

front surface (glass) and the roof surface shall be at least 10 cm. This spacing

also allows air ﬂow to cool the PV module. Install PV modules with a minimum

spacing of 1 cm between neighboring frames to allow for thermal expansion.

Installation Methods

The following installation methods are available:

Bolts or Clamps

Refer to ﬁgure 12 and 13. Do not modify the existing installation holes or drill

new holes. Do not apply excessive pressure on the frame such that the frame

deforms.

•Bolts: Modules must be mounted using the installation holes located on the

rear side of the long frame parts using M8 stainless steel bolts, nuts, and

washers. The torque of screw tightening should between 14N∙m to 20N∙m.

Figure 11: Detail of a bolt installation attachment

Figure 12 : Installation rails

The large size modules are mounted with four outer holes, with max mechanical

loads of 5400 Pa snow (front) and 2400 Pa wind (back).

• Top-down Clamps: Third-party clamps that have been designed for PV

installation structures are an approved installation 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 module clamps should

not contact with the front glass and deform the frame. and avoiding shadowing

eects from the module clamps. The module frame is not to be modiﬁed under

any circumstances. The applied torque value should be big enough to ﬁx the

modules steadily, the torque of screw tightening should between 16 N∙m to

24 N∙m.

Figure 13: Detail of a top-down clamp installation attachment

MAINTENANCE

General

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

– Installation 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 (PH6-9) with a recommended pressure less than 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.

RECYCLING

Yingli Solar is a member of PV Cycle, the European association for voluntary

take back and recycling of PV modules. Please contact PV Cycle at www.

pvcycle.org for details regarding the recycling process.

Meaning of crossed –out wheeled dustbin:

Do not dispose of electrical appliances as unsorted municipal waste, use

separate collection facilities.

Contact your local government for information regarding the collection systems

available.

If electrical appliances are disposed of in landﬁlls or dumps, hazardous

substances can leak into the groundwater and get into the food chain, damaging

your health and well-being.

When replacing old appliances with new ones, the retailer is legally obligated to

take back your old appliance for disposals at least free of charge.

Notes:

• To maximize mounting longevity, Yingli Solar strongly recommends the use of corrosion proof (stainless steel) attachment hardware.

• To check whether the surface of the beam is ﬂat and smooth, or add rubber pads on the beam to prevent the module from being crushed when it is pressed down.

• L represents the length of the long side of the module, the described distances are from the module edge to the middle of the clamp.

• The long-side frames of the module are ﬁxed to the mounting beam or rail by at least 4 clamps that can be ﬁtted with M8 bolts.

• The length of the clamp ≥40 mm, and the module frame to maintain at least 7 mm but not more than 10 mm overlap part, could not contact with the front glass, shall not make the

frame deformation, and should avoid the shading eect of the clamp.

• Tighten M8 bolts to a torque of 14~20 N∙m. The tightening steps as follows: use torque wrench to tighten nut to target torque, nut loosen 90~180 degrees, ﬁnally tighten the nut to the

target torque and reduce the torque attenuation.
