General Installation Manual

HIT Photovoltaic Module

VBHN225DJ06 series

Thank you for choosing Panasonic HIT
photovoltaic (PV) modules. Please read
this manual completely before
installation or use of Panasonic HIT PV
modules. With proper operation and
maintenance, Panasonic HIT PV
modules will provide you with clean,
renewable solar electricity for many
years. This manual contains important
installation, maintenance and safety

information. The word “module” as

used in this manual refers to one or
more PV modules. Retain this manual
for future reference.

SANYO is part of the Panasonic Group
and is in charge of the manufacturing
process for Panasonic HIT PV modules.

Safety Precautions

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

Warning

 All instructions should be read and

understood before attempting to
install, wire, operate, and maintain
the 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.

 The modules generate DC electrical

energy when exposed to sunlight
or other light sources. Although
single module produces only a low
voltage and current, shocks and
burns are still a potential hazard.

 To avoid the hazard of electric

shock and injury, cover the entire
front surface of the modules with a
dense, opaque material such as a
cardboard box, during installation
and handling of the modules.

 The shock hazard increases as

modules are connected in parallel,
producing higher current, and as
modules are connected in series,
producing higher voltages.

 The shock hazard increases as

modules with nominal open-circuit
voltage (Voc) in excess of 50 V,
and/or modules rated for
maximum system voltage in excess
of 50 V.

 To avoid the hazard of electric

shock, work only in dry conditions,
with dry modules and dry tools.

 Do not stand or step on a module

to avoid the hazard of injury and
damage to the module.

 Do not damage the front and back

surface of a module, to avoid the
hazard of electric shock and fire.

 To avoid the hazard of electric

shock and injury, children and
unauthorized persons should not
be allowed near the installation of
modules.

 To avoid the hazard of electric

shock and injury, be sure to
completely ground all modules.

 To avoid the hazard of electric

shock, fire, and injury, do not
disassemble the module, or remove
any part installed by the
manufacturer.

 Unauthorized persons—except the

qualified licensed professional—
should not open the cover of the
junction box to avoid the hazard of
electric shock.

 Do not touch terminals while a

module is exposed to light. Provide
suitable guards to prevent yourself
from direct contact with 30 VDC or
greater to avoid the hazard of
electric shock or injury.

 When carrying a module, two or

more people should carry it by its
frame and wear non-slip gloves (to
avoid injury by a slipping module,
to a foot, or cuts by the edge of a
frame, and so on).

 Do not carry a module by its wires

or junction box, to avoid the
hazard of electric shock, injury or
damage to the module.

 Do not drop anything on the

surfaces of a module, to avoid the
hazard of electric shock, injury, and
damage.

 To avoid the hazard of electric

shock and fire, be sure that all
other system components are
compatible, and they do not
subject the module to mechanical
or electrical hazards.

 Since sparks may occur, do not

install the module where
flammable gases or vapors are
present.

 Never leave a module unsupported

or unsecured.

 Do not drop a module.
 Do not use or install broken

modules to avoid the hazard of fire,
electric shock, and injury.

 Do not artificially concentrate

sunlight on a module to avoid the
hazard of fire or damage.

 Do not touch the junction box

terminals to avoid the hazard of
electric shock and injury.

 Do not change the wiring of bypass

diodes to avoid the hazard of
electric shock and injury.

 Do not disconnect terminals while

modules generate electricity and
connect electrical load to avoid the
hazard of electrical shock.

 Do not touch a 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 front or back

surface with paint or adhesives, to

avoid reducing its’ functionality,

damage, inoperable conditions,
and other unknown troubles.

 VBHN225DJ06 series 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 it’s STC rated
value.

 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

as 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,
which should be followed.

 Be sure that the construction or

structure (roof, 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.

 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.

 Do not use modules of different

specifications in the same system.

 Follow all safety precautions of

other system components used.
