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.

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 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 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 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 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.
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

Figure 7: 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.
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-current­carrying 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 mounting 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. A grounding screw assembly must be attached at a designated grounding hole location using only stainless steel hardware. Insert an M5 stainless steel screw first through the stainless steel cup washer, and then through the grounding hole.
2. Loosely engage a stainless steel backing nut and toothed lock washer to the
screw.
Figure 9: Grounding screw assembly detail
3. Bend the EGC into an omega (Ω) shape to tightly fit between the partially
installed screw head and cup washer. The EGC shall be exclusively in contact with stainless steel.
4. Tighten the screw to 2.3 N∙m torque. The toothed lock washer should be
visibly engaged to the frame.
5. Route the appropriately sized EGC in such a way as to avoid contact with the
aluminum module frame.
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).
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 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 mounting method follows one of the acceptable methods listed below.
