General Information The installation of solar modules requires a great degree of skill and should only be performed by qualified licensed profession als, 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. E ven 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:

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

tools.

• Do not stand or step on modules. Do not puncture, cut,

scratch or damage the backsheet of a module.

Backsheet 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.

• Do not touch a PV module unnecessarily. The glass

surface and frames get hot. There is a risk of burn.

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

General Installation Manual

may contribute to fire hazards. Additional devices such as ground fault, fuses, and disconnects may be required.

• 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 sunlightresistant cable rated for outdoor use (e.g. type UF or USE) , for all wiring that is exposed to weather.

2) Observe the requirements described in sections labeled INSTALLATION

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 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 with a minimum of 1 inch clearance between the roof surface and the modules so that air can circulate.

• 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 corrosive-resistant metal clamps.

• The clamps should be made of aluminum

alloy or other material that will reasonably protect against the a risk of electrolytic corrosion.

• Recommendation of bolt torque range: 16N.m to 20N.m

•

The module was tested using Unirac clamps with the specifications below; if a different clamp is used it must have a design load capacity equivalent to or greater than the load specified in this Manual.

• Sanyo does not provide a warranty for clamps. The modul e warranty Sanyo provides shall be voided if clamps selected by the customer are of an improper material or size.

Operating Conditions

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

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

2) The ambient temperature mus t 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/m

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

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. Under real conditions, a photovoltaic module may experience conditions that produce more current and/or voltage than reported at Standard Test Conditions. Therefore, the 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 Electric 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 temperature factors.

3) The current output for the modules shown in the SPECIFICATIONS section is measured at Standard Test Conditions. These conditions may not be frequently observed in actual practice.

Mechanical Loading

• The modules should be mounted at the four (4) quarter points by the means shown in Figure 2.

• This method offers a maximum load of 2,880N/m2 (60PSF) in a static state on the module surface. Note: This mechanical loading value was tested using the mounting device specified in section “Notes on Installation”.

systems, because of their operating voltage. Therefore, it is not recommended to use them for charging batteries.

• These modules contain factory installed bypass diodes. If these modules are incorrectly connected to each other, the bypass diodes, cable, or junction box may be damaged.

Array Wiring

• The term “array” is used to describe the assembly of several modules on a support structure with associated wiring.

• Use copper wire which insulation is sunlight resistant and can withstand the maximum possible system open circuit voltage.

• Interconnection of modules must be performed in a professional fashion. Wires should be secured and only reasonable slack should be allowed.

• Check local codes for requirements.

Earth Ground Wiring

• All modules should be grounded. All structures or metallic components in direct contact with the modules or electric wires should be properly grounded too. To avoid the hazards of electric shock or fire, modules should be grounded by the frame only at the locations marked in this manual (see grounding methods below).

• T he array frame shall be grounded in accordance with NEC Article 250 (USA) or the CEC in Canada.

• Bonding shall be by a positive means, such as clamping, riveting, bolted or screwed connectors, or welding, soldering or brazing. If the bonding means depends upon screw threads two or more screws or two full threads of a single screw must engage the metal

• Great care should be exercised to ensure that corrosion caused by the grounding means be avoided.

• Corrosion can increase the resistance of the grounding connection on the module, or can even cause the grounding connection to fail entirely. Corrosion can be caused by the effects of weather, humidity, dirt and so on. It can also be caused when two dissimilar metals are in contact (galvanic reaction). ¾ The module frame material is aluminum/magnesium alloy.
