SANYO assumes no responsibility for any infringement of patents or other rights of third parties, which may result from use of modules. No license is granted by implication or under any patent or patent rights. The information in this manual is believed to be reliable, but does not constitute an expressed and/or implied warranty. SANYO reserves the right to make changes to the product, specifications, data sheets and this manual without prior notice.

General Information The installation of solar modules requires a great degree of skill and should only be performed by qualified licensed professionals, including, without limitation, licensed contractors and electricians.

WARNING

• All instructions should be read and understood before attempting to install, wire, operate, and maintain a photovoltaic module. 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.

• The installer assumes the risk of all injury that might occur during

installation, including, without limitation, the risk of electric shock.

• PV modules generate DC(direct current) electrical energy when exposed to sunlight or other light sources. Even a single module produces enough voltage and current, to cause shocks and burns if safety precautions are not followed.

• The shock hazard increases as modules are connected in parallel, producing higher current, and as modules are connected in series, producing higher voltages.

• To avoid the hazard of electric sparks, shock, fire, burns, damage and injury:

• Cover the entire front surface of the PV modules with a dense, opaque material such as a cardboard box, during installation and handling of the modules.

• Work only in dry conditions, with dry modules and dry tools.

• Do not stand or step on a modules.

• Do not puncture, cut, scratch

ordamage the back sheet of a module. Back sheet damage will void a module’s Limited Warranty and may cause fire. Never use

modules with a damaged back sheet.

• Do not allow children and unauthorized persons near the installation or storage site of modules.

• Completely ground all modules.

• Do not disassemble a module,

attempt any repair, open the junction box cover, nor remove any parts installed by Sanyo. There are no user serviceable parts within the module or junction box.

• Unauthorized persons - except the qualified licensed professional should not perform any electrical work, including wiring.

• Wear suitable clothing, guards, eye protection and gloves to prevent you from direct contact with 30 VDC or greater.

• Wear non-slip gloves and carry modules by the frame using both hands. Do not attempt to carry a module by yourself.

• Do not carry a module by its wires or junction box.

• Do not drop anything on the surface of a module.

• Ensure all system components are compatible, and they do not

subject the module to mechanical or electrical hazards.

• Sparks may occur; do not install modules where flammable gases or vapors are present.

• Never rest or leave a module

unsupported or unsecured.

• Do not drop modules.

• Do not use or install broken

modules.

• Do not artificially concentrate

sunlight on a module.

• Do not touch the junction box

terminals.

• Do not change the wiring of

bypass diodes.

CAUTIONS

• Use a module for its intended purpose only.

• Do not treat the back sheet, frame, or front surface with paint or adhesives, to avoid reducing its’ functionality, damage, and causing inoperable conditions, and other unknown troubles.

GENERAL SAFETY Follow all permissions, installation and inspection requirements.

• Before installing modules, contact the appropriate authorities having jurisdiction to determine permissions, installation and inspection requirements, which should be followed.

• Electrically ground modules for all systems of any voltage. If not otherwise specified, it is recommended that requirements of the latest National Electrical Code (USA) or Canadian Electric Code (Canada) or other national or international electrical standards be followed. Refer to “Earth Ground Wiring” section for more information.

• Be sure that the building or structure (roof, façade, etc.) where the modules are being installed has enough strength to support the load of the modules.

• For modules mounted on roofs, special structures may be required to help provide proper installation support.

• Both, roof construction and module installation design have an effect on the fire resistance of a building. Improper installation may contribute to fire hazards. Additional devices such as ground fault, fuses, and disconnects may be required.

Installation

• Do not use modules of different specifications in the same system.

• Follow all safety precautions of other system components which are used.

UL Listing Information

To satisfy UL requirements, when installing the modules, be sure to:

1) Use only stranded or solid copper single–conductor type PV wire or USE2 cable, 12AWG or larger conductors,

rated 600V, 90℃, sunlight resistant, for modules and interconnect wiring that is

exposed to weather.

2) Observe the requirements described in sections labeled INSTALLATION and SPECIFICATIONS.

INSTALLATION General

Please read this guide completely before installing or using your Sanyo PV modules. This section contains important electrical and mechanical specifications.

• Modules should be firmly fixed in place in a manner suitable to withstand all expected loads, including wind and snow loads.

• Metals used in locations that are exposed to moisture shall not be employed alone or in combinations that could result in deterioration or corrosion.

• Install modules where they are not shaded by obstacles like buildings and trees. Pay special attention to avoid partially shading the modules by objects during the daytime.

• If needed, contact an Authorized Representative with questions regarding mounting profiles for Sanyo PV modules.

Notes on Installation

• Clearance between the roof surface and module frame is required to allow cooling air to circulate around the back of the module. This also allows any condensation or moisture to dissipate. Install modules so that air can circulate between the roof and the module.

• Leave 1 inch of clearance between the roof and the module frame. If other mounting means are employed this may effect the temperature of the panel.

• SANYO recommends the installation method and mounting profile shown in Figure 1.

• A module should be attached on a mount or support structure rail by metal clamps. The metal clamp must fulfill the following specifications.

Size: not less than 1.5” (38 mm) width Thickness: not less than 0.12”(3 mm)

Material: aluminum alloy

bolt torque range: 16N.m to 20N.m.

Operating Conditions

SANYO requires that modules be operated within the following Operating Conditions:

1) Terrestrial applications only—no outer space or Special Conditions (see below).

2) The ambient temperature must be within –20°C (-4°F) to 46°C (115°F). The temperature limits are defined as the Monthly Average High or Low of the installation site.

3) The wind pressure load of the installation site should be less than 2,880N/m2 (60PSF).

4) Some environmental conditions could apply. Please refer to Sanyo’s warranty exclusions.

1) Rated electrical characteristics are within –5% to +10% of the values

measured at Standard Test Conditions (STC). STC conditions are; Irradiance of 1000W/m, 25oC cell temperature, and solar spectral irradiance per IEC 60904-3. Note: At the time of shipment, Sanyo guarantees the output level of its modules to be -0/+10% against Rated Power in SPECIFICATIONS based on Sanyo’s factory inspection at STC conditions.

2) Under real conditions, a photovoltaic module may experience conditions that produce more current and/or voltage than reported at Standard Test Conditions. Therefore, Isc value of modules should be multiplied by a factor of 1.25 to determine ampacity. An additional factor of 1.25 may be required for sizing conductors, fuses, disconnects, etc. Please refer to

section 690.8 of the National Electrical Code (NEC) for guidelines. The Voc must be factored according to the lowest recorded ambient temperature recorded for the location where the modules will be installed. Please refer to section

690.7 of the NEC for more information regarding voltage
