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/or maintain the photovoltaic module. PV modules generate DC electrical energy when exposed to sunlight or other light sources. 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 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. To avoid injury or damage:

• Cover the entire front and back

surface of the bifacial modules with a dense, opaque material such as a cardboard box or heavy cloth.

• Work only in dry conditions, with

dry modules and tools.

• Do not stand or step on a module.

• Do not drop a module.

• Do not break the glass surfaces of a

module.

• Do not allow children and

unauthorized persons near the installation site or storage area of modules.

• Completely ground all modules

according to applicable electric codes.

• Do not disassemble the module, or

remove any part installed by the manufacturer.

• Do not open the cover of the

junction box.

• Wear suitable protection (gloves,

clothes, etc.) to prevent direct contact with 30V DC or greater.

• Carry a module by its’ frame with

two or more people.Do not carry a module by its wires or junction box.Wear non-slip gloves.

• Do not drop or place heavy items on

the surfaces of a module (such as tools).

• Check that all other system

components (inverters, wires, racks, balance of system materials, etc.) are mechanically and electrically compatible.

• Do not install the module where

flammable gases or vapors are present.

• Never leave a module unsupported

or unsecured.

• Do not use or install broken

modules.

•

Do not artificially concentrate

sunlight on a module by mirror, Fresnel lens, magnification, etc.

• 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 any portion of the

module with paint or adhesives, to avoid damage to the module, inoperable conditions, or reducing the module’s functionality.

• HIT Double modules have bifacial

performance. These modules produce power from both surfaces of the module at the same time and may generate up to 30% more output power than its’ STC rated value. Refer to Figure 5 for these output electrical characteristics.

• This additional power depends upon

the level of incident light irradiance (albedo) available to the back side of the module, and can be increased or decreased depending upon site characteristics, installation design, weather, etc.

• Treat the back side of the module

the same as the front side and avoid objects that directly shade the solar cells. Refer to “Notes on installation” section.

GENERAL SAFETY Follow all permission, installation and inspection requirements.

• Before installing modules, contact the appropriate authorities to determine permissions, installation and inspection requirements that apply to your site and installation.

• 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.

• Check applicable building codes to ensure that the construction or structure (roof, facade, support, etc.) where the modules are being installed has enough strength.

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

General Installation Manual

• 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 faults, fuses, and disconnects may be required.

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

• Do not use modules of different specifications in parallel.

• Check and follow all safety precautions of other system components used.

UL Listing Information

To satisfy UL standard 1703 requirements, when installing modules, be sure to:

• Use only stranded or solid copper single–conductor type UF cable or USE cable, rated sunlight resistant, for modules and interconnect wiring that is exposed to weather.

• Observe the requirements described in sections labeled INSTALLTION SPECIFICATIONS

INSTALLATION General

Please read this guide completely before installation or use of the modules. This section contains electrical and mechanical specifications needed before using your SANYO PV modules.

• 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.

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

• Modules are water resistant, but not waterproof. Moisture may leak through where the frame and glass connect.

• Please contact your SANYO Authorized Representative with questions regarding mounting profiles for modules if needed.

Notes on Installation

• Clearance between the roof surface and module frame is required to allow cooling air to circulate under the back side 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 as freely as possible.

• Leave 4 inches of clearance between the roof and the module frame.

• SANYO recommends (but does not require) the installation method and mounting profile shown in Figure 1.

• A module should be attached on a mount or support structure rail by metal fittings (Size: 27x27x14mm, Material; SUS304 or NSSC180). The metal fitting must meet the following specifications. Size: not less than 1.06’’ (27mm) width

Thickness: not less than 0.12’’ (3 mm)

Material: Stainless steel

• Bolting torque must be more than 8N.m.

The following information is provided to help customers obtain good performance without exceeding a module’s operating conditions or warranty parameters.

• Do not artificially concentrate sunlight on a module by mirror, Fresnel lens, magnification, etc.

and

• The surface upon which modules are installed is recommended to be flat, to prevent artificially concentrated sunlight.

• Additional output power from the back face of the panel can be increased or decreased depending upon angles of installation, height from surfaces, shade from structures or rails, and the albedo of surrounding surfaces.

• Please see Figure 6 for the effect of angles of installation on output power.

• The height of a module above a surface affects the power potential of the module’s back face.

• When p ossible, maximize the height of modules above surfaces in order to maximize ambient light beneath the modules.

• Always position support structures and rails along the edges of a module, or between modules, and do not allow rails to shade a module’s back surface.

• Light colored surfaces reflect more light than dark colored surfaces. Installing HIT Double modules over light colored surfaces will increase the output power potential from the back side.

within the following conditions:

1) Terrestrial applications only—no outer space use.

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 low and high of the installation site.

3) The wind pressure load of the installation site should be less than 1,440Pa (30PSF)*. *Note: HIT Double modules were tested at 30PSF at UL’s testing lab. Modules of exactly the same structure successfully achieved 50PSF load ratings at JET’s (Japan Electrical Safety & Environment Technology Laboratories) testing lab, and are certified as fully compliant at 50PSF.

4) Modules must not be installed nor operated in areas where, salt, hail, snow, sand, dust, air pollution, chemically active vapors, acid rain, soot, etc., are excessive.

SPECIFICATIONS

• Rated electrical characteristics are

within –5% to +10% of the values measured at STC. STC Conditions are; Irradiance of 1000W/m temperature, and solar spectral irradiance per IEC 60904-3.

• Under normal conditions, a

photovoltaic module may experience conditions that produce more current and/or voltage than reported at Standard Test Conditions. Accordingly, the values of Isc and Voc marked on modules should be multiplied by a factor of 1.25 when determining voltage ratings, conductor capacities, fuse sizes, and size of controls connected to the module output.

Refer to Section 690 of the National Electrical Code (NEC) for an additional multiplying factor of 1.25, which may be applicable.

• 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

• HIT Double modules should be

mounted at four (4) symmetrical quarter points within the shaded areas (Range A) shown in Figure 4, or any mounting method with a continuous attachment, by which those four points are included in each side.

• The four symmetrical quarter point

method offers a maximum loading of
