General Information This manual contains information regarding the installation and safe handling of TSMC Solar modules. All instructions must be read and understood before attempting installation. If there are any questions, please contact your sales representative or TSMC Solar for further information. Installers must conform to all safety precautions in the manual when installing modules. Before installing, the installer must become familiar with the mechanical and electrical requirements for PV systems.

4. Warnings and Cautions 4.A Warning All instructions must be read and understood before attempting to install, wire, operate, and/or maintain the module. When modules are exposed to sunlight or other light sources, they generate DC electrical energy. Contact with electrically active parts of the module such as terminals can result in burns, sparks, and lethal shock whether the module is connected or disconnected. Shock hazard increases as modules are connected in parallel, producing higher current, and as modules are connected in series, producing higher voltage. The installer assumes the risk of all personal injury or property damage that might occur during installation and handling of modules. Do not disassemble, modify or remove parts of the module. 4.B Cautions Use modules for their intended purpose ONLY. Do not treat any portion of the module with paint or adhesives, to avoid damage to the module, inoperable conditions, or reducing the module s functionality. 5. Handling and Installation Safety To avoid injury or damage: Wear non-slip gloves. Do not allow children or unauthorized persons near the installation site or module storage area. Do not wear metallic rings, jewelry or devices while installing or troubleshooting photovoltaic systems. Work only in dry conditions, with dry modules and tools. Do not install the module where flammable gases or vapors are present. Never leave a module unsupported or unsecured. The back of the module must not be exposed to direct sunlight for extended periods of time during storage or during the installation process to avoid the possibility of heat damage. When disconnecting wires connected to a module that is exposed to sunlight, an electric arc may result. Such arcs may cause burns, may start fires and may otherwise create problems. Be extremely careful! Use only equipment, connectors, wiring and mounting structures suitable for use in a photovoltaic system. Series connected modules should always be of uniform configuration and electrical specifications. Cover the entire front surface of the modules with a dense, opaque material such as a cardboard box, when working on a connected system cannot be avoided. Check for remaining voltage before starting, and observe the relevant local safety regulations for such working conditions. 6. Installation and Operation Photovoltaic systems must be installed by qualified and experienced personnel. Install PV modules with a minimum spacing of 10mm between neighboring frames to allow for thermal expansion. Do not step on, or place objects on the module during or after installation. Although TSMC Solar modules

are quite rugged, the glass may be broken if it is dropped or hit by tools or other objects and the module will no longer work properly. The module must not be exposed to concentrated sunlight, e.g. sunlight focused by mirrors, lenses or other magnifiers. The module frame is made of anodized aluminum, and therefore corrosion can occur if the module is placed in a salt-water environment in contact with a rack made of another type of metal (Electrolytic Corrosion). If required, stainless steel washers can be placed between the module frame and support structure to prevent this type of corrosion. Any module support structures that are to be used to support TSMC Solar modules must be wind rated and approved for use by the appropriate local and civil codes prior to installation. In Canada, the installation must be done in accordance with CSA C22.1, Safety Standard for Electrical installations, Canadian Electrical Code, Part I. Do not drill holes in the module frame Any module without a frame (laminate) shall not be considered to comply with the requirements of UL 1703 unless the module is mounted with hardware that has been tested and evaluated with the module under this standard or by a field Inspection certifying that the installed module complies with the requirements of UL 1703. The module type has been qualified as Application Class A under IEC 61730-1. All measurements in mm [inches] Figure 1 Module Physical Specifications

The requirements of the National Electrical Code (NEC) in Article 690 shall be followed to address these increased outputs. In installations not under the requirements of the NEC, the values of ISC and VOC marked on this module should be multiplied by a factor of 1.25 when determining component voltage ratings, conductor ampacities, overcurrent device ratings, and size of controls connected to the PV output. The multiplying factor at conditions of an irradiance of 1250 w/m 2, AM1.5 spectrum, and a cell temperature of -10 C (+14 F) for Voc is 1.25 and at cell temperature of 75 C (167 F) for Isc it is 1.25. For field connections, use approved PV Copper wire only, minimum No. 14 AWG (2.5mm 2 ) wires insulated for minimum of 90 C, rated for wet conditions and resist to ultra violet radiation (where exposed)

6.C Electrical Wiring Method To ensure proper system operation, correct cable connection polarity (Figure 2) must be observed when connecting the modules to other modules. If not connected correctly, the bypass diode could be destroyed. If modules are connected in series, the total voltage is equal to the sum of the individual module voltages. Only connect modules or series combinations of modules with the same voltage. If modules are connected in parallel, the total current is equal to the sum of individual module current. Series Wiring (voltage additive) Parallel Wiring (current additive) Figure 2 Wiring Methods 6.D Correct Wiring Scheme Match the polarities of cables and terminals when making the connections; failure to do so may result in damage to the module. Avoid immersion of cables and connectors in water and site them away from areas prone to water collection. Ensure a minimum clearance of 10mm between the ground/roof surface and the cables/connectors after installation. Fix the cables/connectors to the module or mounting structure before commissioning the system. Use the tool recommended by connector manufacturer when disconnection of connector is needed. Example: open-end spanner PV-MS (Figure 3). When routing cable, ensure forces on the cable do not create a visible deformation in the sealing portion of the insulation. Do not create cable bends less than the 26mm minimum bending radius of our cables (Figure 4) In order to limit voltages induced by indirect lightning strikes, keep the area of all conductor loops to a minimum

Mounting hardware locations for both methods are illustrated in this section. No matter which method is used, the modules are recommended to be mounted in portrait orientation (short side parallel to ground) for best performance. If modules are mounted in landscape orientation (long side parallel to ground), shading must be minimized as this orientation can significantly increase the impact of shading on module performance. Please do not mount the module in landscape orientation with less than 10 tilt angle. Clamp Method: Modules mounted with clamps must have the center of the clamp positioned within the shaded clamp zones as shown in Figure 5. This method enables a maximum mechanical loading of 2,400N/m2 (50PSF) (IEC),

All measurements in mm [inches]. Figure 5 Clamp Zone Bolt Method: The frame of each module has 8 x 6.6 mm [0.26 ] mounting holes. Modules mounted by bolting the frame to mounting structure must use the 4 mounting hole locations denoted M1 in Figure 6. This method enables a maximum mechanical loading of 2,400N/m2 (50PSF) (IEC) too, in a static state on the module surface. The 4 mounting holes located further towards the short edge of the frame than the M1 holes are reserved for future product use and may NOT be used with current products.

All measurements in mm [inches] Figure 6 Bolt Method Mounting Hole Locations 6.G Tilt Angle Selection Module tilt angle is measured between the module and the ground as shown in Figure 7, with modules generating the maximum power when they face sunlight directly (incident light perpendicular to module front surface). The modules should be oriented to face south in the Northern Hemisphere and face north in the Southern Hemisphere. For installations where the modules are mounted on a permanent structure, they should be tilted so that the energy production from the modules will be maximized on an annual basis. Generally this result will be achieved when the tilt angle is near the value of the latitude of the mounting site. Use photovoltaic system simulation tools or consult professional installers / system integrators to determine optimum tilt angle. Tilt angles of at least 10 are recommended to reduce dirt or other substance accumulation. Please do not mount the module in landscape orientation with less than 10 tilt angle. Figure 7 Tilt Angle Definition

6.H Fire Class Rating These modules have achieved a Fire Resistance Rating of Class C. The fire rating of this module is valid only when mounted in the manner specified in the mechanical mounting instructions as described in Section 8 of this document, Mounting Methods and Configurations. In rooftop installations, installed modules must have a standoff height between roof and module of more than 9cm [3.54 ] for airflow passage. Note: During UL testing, the slope of the fire class test for this module is 5 in/ft. Module Roof Standoff Height 9cm [3.54 ] Figure 8 Standoff Height 7. Grounding A 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 The company installing the modules will be responsible for professional grounding of the modules. The factory-provided aluminum frame must be grounded. All grounding must be performed to be compliant with the latest regulations that are applicable for the jurisdiction where the system is installed, e.g. the NEC (National Electric Code) in the United States. If the building is already equipped with an exterior lightning protection system, the PV installation must be integrated into the protection system against direct effects of lightning There are eight 4.2mm [0.165 ] grounding holes on the module frame, four on each of the module s short sides. The grounding holes are identified by a grounding mark (Figure 9) located next to each hole. Figure 10 illustrates grounding the module. Ground wires must be connected to the module s frame at one of the grounding holes. The ground wire must not be smaller than No.14 AWG (2.5 mm²), and sized according local regulations, e.g. the NEC (National Electric Code) in the United States. The ground holes must be used with M4 screws. The length of these screws must not exceed 20 mm [0.78 ] in order to avoid contacting the back glass of the module. The screw length must not be less than 12 mm [0.47 ]. The torque to be applied to the M4 screw is 3.0~4.0 N-m [22.1~26.6 in-lb]. The material of the frame is aluminum alloy. To avoid galvanic corrosion, all fasteners (nuts, bolts, washers,

screws, etc.) must be stainless steel unless otherwise specified. All measurements in mm [inches] Figure 9 Grounding Mark and Hole Dimensions Figure 10 Grounding with Washers WEEB grounding (Certified by UL only) In addition, WEEB (Washer, Electrical Equipment Bond) grounding parts with UL 467 listing can be used with TSMC Solar module. The WEEB parts must be installed in accordance to the manufacturers installation instruction. The diagram below (Figure 11) shows how WEEB grounding parts are used with the end/middle

clamp in the installation. And the dimension of end/middle clamp for WEEB grounding parts have to follow our proposed requirement that the clamp overlap the module frame by at least 5 mm, the clamp overlap length is at least 38 mm and the fasteners torque of at least 10 ft-lbs (13.5N-m) is suggested. Figure 11 Grounding with Clips 8. Mounting Methods and Configurations The module is considered to be in compliance with UL 1703 only when the module is mounted in the manner specified by the mounting instructions below As introduced in section 6.F, there are two mechanical installation methods: Clamp and Bolt. Both methods of mounting and configuration are explained below, respectively. In all cases, PV modules are to be mounted over a fire resistant roof covering rated for the application. Clamp Method The module is secured to the mounting structure by clamping. A clamping solution requires a top clamp piece that braces the front of the module frame, and a rail or bottom clamp piece that supports or clamps the bottom of the module. The top clamp pieces hold the module securely at four points against rails or bottom clamps. Except for modules at beginning and end of a row of modules, middle clamps can be used to hold two modules per clamp. For the allowed location of each clamp on a PV module, see the clamp zone definition in section 6.F, Figure 4. An example of top, bottom and middle clamp is shown in Table 1 When using clamping method, make sure the clamping overlap is positioned according to figure 12 and figure 13. The module clamping method is shown in figure 14 and the clamping material should be anodized aluminum alloy. Warranty may be void if inappropriate clamps or unsuitable clamping method are used.

Figure 14 Module Clamp Mounting Method

Bolt Method The module can be mounted by bolting the frame to mounting structure. This method requires 4 sets of: M6 bolt, M6 spring washer, M6 flat washer and M6 nut per module. There are eight mounting holes on the back side of module, however only the 4 mounting hole locations denoted M1 in Figure 6 can be used. These 4 holes are offset from the short edge of module by 407.5mm [16.04 ]. The installation method (Figure 15) requires that the spring washer be first placed on the bolt, followed by the insertion of the bolt first through the module mounting hole in the aluminum frame then through the system rail. Finally, after putting the flat washer and nut on the bolt, use torque of 6.1 N-m to screw the nut tight to complete the installation. The bolt mounting method cross section is as shown in Figure 16.
