Thank you for choosing Panasonic photovoltaic module HITTM.

Please read this manual completely before you install or use of

HITTM. With proper operation and maintenance, HITTM will

provide you with clean, renewable solar electricity for many

years. This manual contains important installation, mainte-

nance and safety information. The word “module” as used in

this manual refers to one or more PV modules. Retain this

SAFETY PRECAUTIONS

WARNING

CAUTIONS

 All instructions should be read and

understood before attempting to

install, wire, operate, and maintain

the module.

 The installation of modules requires

a great degree of skill and should

only be performed by qualified

licensed professionals, including,

without limitation, licensed contrac-

tors and licensed electricians.

 The installer assumes the risk of all

injury that might occur during in-

stallation, including, without limita-

tion, the risk of electric shock.

 Before installing modules, contact

the appropriate authorities to de-

termine permissions, installation

and inspection requirements, which

should be followed.

 Be sure that the construction or

structure (roof, etc.) where the

modules are being installed has

enough strength.

 Both roof construction and module

installation design have an effect on

the fire resistance of a building.

Improper installation may contrib-

ute to fire hazards. Additional de-

vices such as ground fault, fuses,

and disconnects may be required.

 For a non-integral module or panel,

the assembly is to be mounted over

a fire resistant roof covering rated

for the application.

 For modules mounted on roofs,

special construction or structures

may be required to help provide

proper installation support.

 Do not install the module where

flammable gases or vapors are pre-

sent.

 Do not use modules of different

specifications in the same system.

 Follow all safety precautions of

other system components used.

To avoid the hazard of electric shock,

sparks, fire and injury

 The modules generate DC electrical

energy when exposed to sunlight or

other light sources, so cover the

entire front surface of the modules

with a dense, opaque material such

as a cardboard box, during installa-

tion and handling of the modules.

 The shock hazard increases as mod-

ules are connected in parallel, pro-

ducing higher current, and as mod-

ules are connected in series, produc-

ing higher voltages.

 The shock hazard increases as mod-

ules with nominal open-circuit volt-

age (Voc) in excess of 45 V, and/or

modules rated for maximum system

voltage in excess of 45 V.

 Wear suitable clothing, gloves and

guards to prevent from direct con-

tact with 30 VDC or greater.

 Work only in dry conditions, with

dry modules and dry tools.

 Children and unauthorized persons

should not be allowed near the

installation of modules.

 Do not puncture or damage the

back sheet of a module. Do not use

the PV module and make a replace-

ment, when scratch exposing con-

ductive part is found on the back

sheet.

 Do not disassemble the module, or

remove any parts installed by the

manufacturer.

 Do not open a junction box's lid.

 Do not touch the junction box ter-

minals.

 Do not change the wiring of bypass

diodes.

 Do not connect or disconnect termi-

nals while modules generate elec-

tricity and connect electrical load.

To avoid the hazard of injury, burn and

damage to the module

 Use a module for its intended pur-

pose only.

 Be sure that all other system com-

ponents are compatible, and they

do not subject the module to me-

chanical or electrical hazards.

 Do not artificially concentrate sun-

light on a module.

 Do not stand or step on a module.

 When carrying a module, two or

more people should carry it by its

frame and wear non-slip gloves.

 Do not carry a module by its wires

or junction box.

 Do not drop a module.

 Do not drop anything on the sur-

face of a module.

 Do not hit the back sheet of a mod-

ule by the connector or other

things.

 Do not disassemble a module, at-

tempt any repair, open the junction

box cover, nor remove any parts

installed by Panasonic. There are no

user serviceable parts within the

module or junction box.

 Do not treat the back sheet or front

surface with paint or adhesives.

 Do not use or install broken mod-

ules. If you find a breakdown such

as glass breakage, contact the pro-

fessional installer to replace it

promptly.

 Do not touch a module unnecessari-

ly. The glass surface and frames get

hot.

 In some areas, local electrical codes

may govern the installation and use

of modules.

 Never leave a module unsupported

or unsecured.

MODULE SPECIFICATIONS

 Module specifications are shown in

Table 1-1, 1-2 and Figure 1-1, 1-1-a,

1-1-b, 1-2. (Electrical specifications,

mechanical specifications, module

dimensions)

1) Rated electrical characteristics are

within the range of +10% to –0% of

the values measured at Standard

Test Conditions (STC). Irradiance of

1000W/m2, 25±2℃ cell tempera-

ture, AM1.5 and solar spectral irra-

diance according to IEC 60904-3.

2) Under normal conditions, a module

may experience conditions that

produce more current and/or volt-

age than reported at standard com-

ponent test conditions. Accordingly,

the values of Isc and Voc should be

multiplied by a factor of 1.25 when

determining voltage ratings, con-

ductor capacities, fuse sizes, and

size of controls connected to the

module output.

3) The current output for the modules

shown in the Specifications is meas-

ured at Standard Test Conditions.

These conditions may not be fre-

quently observed in actual practice.
