C @us Fi ure 1 Important -! Please read this instruction manual in its entirety before installing, wiring or using this product in any way. Failure to comply with these instructions will invalidate the SunPower Limited Warranty for PV Modules. 1.1 Disclaimer of Liability The installation techniques, handling and use of this product are beyond company control. Therefore, SunPower does not assume responsibility for loss, damage or expense resulting from improper installation, handling or use. 1.2 Underwriters Laboratories (UL) Listing Information This product meets or exceeds the requirements set forth by UL1703 for PV Modules. This UL Standard covers flat -plate PV modules and panels intended for installation on buildings or those intended to be freestanding. To satisfy the listing for this product the modules must be mounted with a rack or standoff structure. The UL listing does not include integration into a building surface because additional requirements may apply. This product is not intended for use where artificially concentrated sunlight is applied to the module. 1.3 Limited Warranty Module limited warranties are described in full in the SunPower warranty certificates obtainable at www.sunpowercorr).com. In summary. the Limited Warranties do not apply to any of the following; PV modules which in SunPower's absolute judgment have been subjected to: misuse, abuse, neglect or accident; alteration, improper installation, application or removal. Including, but not limited to installation, application or removal by any party other than a SunPower authorized dealer; non - observance of SunPower's installation, users and /or maintenance instructions; repair or modifications by someone other than an approved service technician of SunPower; power failure surges, lightning, flood, fire, accidental breakage or other events outside SunPower's control. 2.0 Safety Precautions Before installing this device, read all safety instructions in this document. Dangers Module interconnection cables pass direct current (DC) and are sources of voltage when the module is under load and when it is exposed to light. Direct current can arc across gaps and may cause injury or death if improper connection or disconnection is made, or if contact is made with module leads that are frayed or torn. Do not connect or disconnect modules when current from the modules or an external source is present. Cover all modules in the PV array with an opaque cloth or material before making or breaking electrical connections. It is imperative use the supplied locking connectors and safety clips in order to defend against untrained personnel disconnecting the modules once they have been installed. All installations must be performed in compliance with the National Electrical Code (NEC) and any applicable local codes. Pr SUNPOWER CORPORATION Safety and Installation Instructions - Document 001 -14158 Rev *I • There are no user serviceable parts within the module. Do not attempt to repair any part of the module. • Installation should be performed only by authorized personnel. • Remove all metallic jewelry prior to installing this product to reduce the chance of accidental exposure to live circuits. • Use insulated tools to reduce your risk of electric shock. • Do not stand on, drop, scratch, or allow objects to fall on modules. • If the front glass is broken, or the back sheet is torn, contact with any module surface or module frame can cause electric shock. • Broken j -boxes and /or broken connectors are electrical hazards as well as laceration hazards. The dealer or installers should remove the module from the array and contact the supplier for disposal instructions. • Do not install or handle the modules when they are wet or during periods of high wind. • Contact your module supplier if maintenance is necessary. • Save these instructions! 3.0 Electrical Characteristics The module electrical ratings are within 10% of UL's measured values under Standard Test Conditions (STC) of 1 kW /m2 irradiance with Air Mass of 1.5 solar - spectral- irradiance - distribution and a cell temperature of 254 C. The electrical characteristics of SunPower modules are listed in Figure 2 of the appendix. If an installation involves a SunPower module which does not appear on this list please consult the product label on the back of the module or visit www.Sunpowercorp.com for the product datasheet. Bypass diodes for each module are rated and factory installed in the modules. The diodes are one of the following ratings; 1. 8A, 45 PIV (Peak Inverse Voltage) for 72 & 96 cell modules. 2. 12A, 200 PIV (Peak Inverse Voltage) for 96 (commercial use), 128 cell modules. A photovoltaic module may produce more current and /or voltage than reported at STC. Sunny, cool weather and reflection from snow or water can increase current and power output. Therefore, the values of I. marked on the module should be multiplied by a factor of 1.25 when determining component ampacity ratings to comply with NEC, Article 690.8(A). An additional 1.25 multiplier may be required by the NEC for sizing fuses and conductors as described in NEC Section 690 -8(B). The maximum module string open circuit voltage (Vo,) shall be calculated as the sum of the rated open- circuit voltage of the series - connected photovoltaic modules corrected for the lowest expected ambient temperature (NEC 2008, Article 690.7). One source for statistically valid, lowest- expected, ambient temperature design data for various locations is the Extreme Annual Mean Minimum Design Dry Bulb Temperature found in the ASHRAE Handbook — Fundamentals. These temperature data can be used to calculate maximum voltage using the manufacturer's temperature coefficients relative to the rating temperature of 25°C (NEC 2011, Article note to 690.7). SunPower recommends the use of open- circuit voltage temperature coefficients listed in Figure 2 of the appendix, when determining Maximum System Voltage 3.1 Fire Rating The module is Class C fire rated. 4.0 Electrical Connections Modules may be connected in series and /or parallel to achieve the desired electrical output as long as certain conditions are met. Please use only the same type of modules in a combined source circuit. The connectors on SunPower modules ship with a locking safety clip, which once connected requires the use of a tool to disconnect module -to- module connections. This defends against untrained personnel disconnecting the modules when under load (which may cause injury or death as stated in Section 2.0) and complies with the NEC 2008 code for safety with PV connectors, 4.1 Equipment Grounding To reduce the possibility of electrical shock, ground the frame of the module or array before wiring the circuit using a grounding method that meets NEC requirements for grounding solar electrical systems. In order to install in accordance with the UL listing of this product, SunPower modules shall be grounded using grounding hardware that has been certified to r O.JANUARY 2011 SunPower Corporation. All rights reserved. Specifications included in this manual are subject to change without notice. meet requirements for grounding systems in UL467, UL1703, or UL1741 on anodized aluminum frames. SunPower recommends using 1 of the following five methods of grounding the module frame. In addition, avoid corrosion due to the use of dissimilar metals (we suggest stainless steel between copper and aluminum). 1) Attach a ground conductor to a grounding lay -in lug mounted at one of the four designated 0.17" grounding holes on the module frame. Alternatively, any unused mounting hole can be used to mount the lug. Use a grounding lug such as Ilsco GBL -4DBT, Burndy CL50 -DB- T or Tyco Solklip 1954381 -2, and stainless steel hardware (bolt, washers, and nut). A star washer should be used between the grounding lug and the module frame in order to break through the anodizing and establish electrical contact with the aluminum. The assembly must end with a nut and be torqued between 20 inch -pound to 25 inch -pound for a #10 -32 bolt. A lock washer or other locking mechanism is needed to maintain tension between the bolt and the assembly. The copper conductor must be attached to the ground lug using the stainless steel set screw provided by the manufacturer. Please refer to NEC Article 690 on grounding PV arrays for specific requirements. 2) SunPower systems may also be grounded through the use of SunPower supplied "IFF clips" which are UL Listed (1703 and 1741). A minimum torque of 10 in -Ibs is required for grounding, however higher torque values will be required to ensure structural integrity. General torque values are 35 to 45 in -Ibs for a 1/4 -20 or M6 bolt, but may be higher in specific applications. When using these clips, the array frame (racking) must be grounded in accordance with NEC Article 250. To ensure system safety and structural integrity, strict adherence to application- specific SunPower documentation is required. 3) The SunPower PV Grounding Clip may also be used only in applications where the modules are attached to a SunPower torque tube, #111380. This device consists of Rail Clip #1505 -994, Retainer Bar #1504 -979, Carriage Bolt (2) #1506 -224, Nut (2) #1503 -098, Lock Washer (2) #1503 -099. Hardware must be torque to 120 in -Ibs. The PV Grounding Clip has been evaluated for bonding to the Torque Tube for use with an over - current protective device rated 20 Amps maximum and a circuit capacity of 600 V, 5000 Amps APPROVAL OF 4) Sunpower modules may also be grounded through the use of an ETL Listed PV Attach Grounding washer #1508 -666, which may be used only in applications where the modules are attached to a Sunpower W E EBS TO Saddle #1508 -738 or #1508 -741 using a 1/4 inch rivet. GROUND 5) If the Unirac Solarmount system is used for mounting the modules, grounding is achieved using either the Wiley Electronics WEEB UMC SUNPOWER or UGC -1 grounding clips in combination with UniRac's Mid or End clamps and 1/4 -20 bolt and flanged nut , torqued to 120 in -Ibs. If the MODULES Solarmount -I system is used grounding is achieved with the UniRac UGC -2 grounding clips in combination with UniRac's Mid or End clamps and Sliders with a 1/4 -20 bolt and flanged nut torqued to 120 in -Ibs. When using methods 2, 3, 4 or 5 the array frame (racking) must be grounded in accordance with NEC Article 250. To ensure system safety and structural integrity, strict adherence to application - specific SunPower documentation is required. 4.2 System Grounding Re�jqWJb&,, flowing tables for the proper grounding to se for the installati rt P�11 t .

For optimal performance, SunPower PV modules must only be used in configurations where the positive polarity of the PV array is connected to ground. Failure to comply with this requirement will reduce the performance of the system and invalidate SunPower's Limited Power Warranty for PV Modules. For more information on grounding the system correctly, visit our website at www.sunpowercorp.com /inverters or contact SunPower technical support at 1- 877 - SUN -0123. 4.3 Series Connection The modules may be wired in series to produce the desired voltage output. Do not exceed the maximum system voltage shown in Figure 2. 4.4 Parallel Connection The modules may be combined in parallel to produce the desired current output. Each series string or module may be required to be fused prior to combining with other strings. Figure 2 describes the maximum fuse size allowed (number of modules which can be connected in parallel and protected by one fuse). Please refer to the NEC Article 690 for additional fusing requirements. 5.0 Module Mounting The SunPower Limited Warranty for PV Modules is contingent upon modules being mounted in accordance with the requirements described in this section. 5.1 Site Considerations SunPower modules should be mounted in locations that meet the following requirements: Operating Temperature: All SunPower modules must be mounted in environments that ensure SunPower modules will operate within the following maximum and minimum operating temperatures: Maximum Operating +85' Celsius, +185' Temperature Fahrenheit Minimum Operating -40 ' Celsius, -40' Fahrenheit Temperature Care should be taken to provide adequate ventilation behind the modules, especially in hot environments. Desian Strength: SunPower modules are designed to meet a maximum positive (or upward, e.g. wind) and negative (or downward, e.g. static load) design pressure of 2400 Pa (Pascals; 245 kg /m2) when mounted in all of the mounting configurations specified in Section 5.2. Design strength of 2400 Pa corresponds approximately to a wind speed of 130 km /h (81 mph), as tested All rights reserved. Specifications included in this manual are subject to change without notice.
