General Installation Manual

GENERAL

Please read this guide completely 

before installation or use of the 

modules.

OPERATING CONDITIONS

Panasonic recommends that modules 

be operated within the following 

Operating Conditions. An installation 

location with conditions beyond the 

Operating Conditions or with other 

Special Conditions (see below) should 

be avoided. Operating Conditions of 

Panasonic modules are as follows:

1) The modules should be operated 

only in terrestrial applications. No 

space or other Special Conditions.

2) The operating temperature must be

within 

-40ºF(-40ºC) to 185ºF(85ºC)

.

3) The wind pressure load of the 

installation site should be less than 

Load Resistance shown in “Mount 

Locations and Load Resistance” table 

in Figure 1.

UNPACKING AND HANDLING

•  Do not hit the back sheet of a 

module by the connector when 

unpacking and handling.

•  Please do not expose the connector 

the rain water and dust.

•  To avoid the damage of the back 

sheet by the connector, fix the 

cables to the frame with tape after 

unpacking. (refer Figure 3)

•  Do not handle modules by their 

cables or junction box. Handle 

them by the frame with both hands 

in any situation.

•  The anti-reflection glass of a 

module is easy to be soiled, when it 

is grasped by hand or hand gloves. 

So it is recommended to hold 

cardboard or frames when carrying 

or installing the solar module. 

When cables and connectors 

touch the surface of the glass, it 

may soil the surface too. It is also 

recommended to avoid contact of 

cables and connectors with surface 

of the glass.

CABLE MANAGEMENT

To ensure a long life span of the cables

and reduce the potential for damage to

the cables, follow the instructions 

below:

•  To prevent stress on the junction 

box casing, ensure the cable exits 

the junction box in a straight line 

before any bend in the cable.

•  The cables must have a minimum 

bending radius of 1.2 in (30 mm) 

to avoid damage to the insulation 

(refer Figure 4).

•  Ensure cables do not hang loose 

where they may be damaged 

through friction or stress, e.g., 

caused by mechanical abrasion or 

grazing animals.

•  Protect connectors from falling or 

dropping water by locating them 

directly beneath a module

•  Cables must be firmly secured 

to the structure, without over-

tightening, as this can deform the 

cable insulation using UV-resistant 

cables.

•  When securing the connector, place 

it so that it has with sufficient air 

circulation all around. This allows 

the connector to dry effectively 

and avoids the risk of damage or 

degradation of the connection

•  Secure the cable either side of the 

connectors to ensure no stress is 

exerted on the connector casing or 

cable entry,

•  To enable correct cooling and 

drying of the connectors, do 

not add extra protection to the 

connector e.g., heat shrink, grease 

or tape.

BYPASS DIODE

•  When the modules in series strings 

are shaded partially, it may cause 

reverse voltage across cells or 

modules, because the current from 

other cells in the same series is 

forced to flow through the shaded 

area. This may cause undesirable 

heating to occur. 

•  The use of a diode to bypass 

the shaded area can minimize 

both heating and array current 

reduction.

•  All modules are equipped with 

factory installed bypass diodes. The 

factory installed diodes provide 

proper circuit protection for the 

systems within the specified 

system voltage, so that you do not 

need any other additional bypass 

diodes.
