2. APPLICATIONS

KDxxxGX-LPx series modules are a reliable, virtually
maintenance-free direct current (DC) power source,
designed to operate at the highest level of efficiency.
KDxxxGX-LPx series modules are ideal for remote home,
water pumping, utility-tied, telecommunications and
many other applications either with or without using
storage batteries.

3. WARNINGS & SAFETY

PV modules generate electricity when exposed to light.
Arrays of many modules can cause lethal shock and
burn hazards. Only authorized and trained personnel
should have access to these modules. To reduce the risk
of electrical shock or burns, modules may be covered
with an opaque material during installation. Do not touch
live terminals with bare hands. Use insulated tools for
electrical connections. Do not use these modules for
solar concentration.

PERMIT

・ Before installing your PV system, contact local

authorities to determine the necessary permits,
installation and inspection requirements.

INSTALLATION AND OPERATION

・ Systems should be installed by qualified personnel only.

The system involves electricity, and can be dangerous if
the personnel are not familiar with the appropriate safety
procedures.

・ Do not step on the module.

・ Although

KDxxxGX-LPx series modules are quite

durable, the glass can be broken (and the module will no
longer work properly) if it is dropped or hit by tools or
other objects.

・ The module frame is made of anodized aluminum, and

therefore corrosion can occur if the module is subject to
a salt-water environment and is in contact with another
type of metal (electrolytic corrosion). If required, PVC or
stainless steel washers can be placed between PV
module frame and support structure to prevent this type
of corrosion.

・ KDxxxGX-LPx series module frame(s) must be

attached to a support structure by one of the methods
described in Section 6, Installing

GROUNDING

・ Refer to “Grounding” section.

BATTERY

・ When PV modules are used to charge batteries, the

battery must be installed in a manner, which will ensure
the performance of the system and the safety of its users.

Follow the battery manufacturer’s safety guidelines
concerning installation, operation and maintenance
recommendations. In general, the battery (or battery

bank) should be kept away from people and animals.
Select a battery site that is protected from sunlight, rain,
snow, debris, and is well ventilated. Most batteries
generate hydrogen gas when charging, which can be
explosive. Do not light matches or create sparks near
the battery bank. When a battery is installed outdoors, it
should be placed in an insulated and ventilated battery
case specifically designed for this purpose.

4. SITE SELECTION

In most applications, KDxxxGX-LPx series modules should
be installed in a location where they will receive maximum
sunlight throughout the year. In the Northern Hemisphere,

KDxxxGX-LPx series modules are

the modules should typically face south, and in the
Southern Hemisphere, the modules should typically face
north. Modules facing 30 degrees away from true South (or
North) will lose approximately 10 to 15 percent of their
power output. If the module faces 60 degrees away from
true South (or North), the pow er loss will be 20 to 30 percent.
When choosing a site, avoid trees, buildings or obstructions,
which could cast shadows on PV modules especially during
the winter season when the arc of the sun is lowest over the
horizon.

5. MODULE TILT ANGLE

KDxxxGX-LPx series modules produce bigger power when

they are pointed directly at the sun.
For grid tie installations where the PV modules are attached
to a permanent structure, PV modules should be tilted at an
angle equal to the site's latitude. This will typically result in
the highest annual energy output.

6. INSTALLING KDxxxGX-LPx SERIES
MODULES

To install the module, use bolt and nut on installation holes
which are opened in the module frame and install the
module by following the instruction belo w.

The minimum spacing of 2” (50 mm) is required between PV
module and the mounting surface around the perimeter of
PV module.
installed in various applications utilizing a variety of support
structure options and attachment methods. For optimal
performance in all applications, clearance between the
module frame and the mounting surface is required to allow
cooler ambient air to circulate around the back of the
module and to avoid the module and / or wiring damage. A
minimum of .13” (3.2 mm) spacing must also be maintained
between module frames to allow for thermal expansion.

KDxxxGX-LPx series modules may be

KDxxxGX-LPx series modules may be attached to a

support structure by the following methods. When installing
modules in snowy area, an appropriate countermeasure
has to be taken to prevent possible damages to the lo wer
side frame by slipping snow (e.g. attach supporting parts to
the lowest modules.). Any damage caused by snow or such
countermeasure is not covered under warranty.

BOLTING: Utilizing 5/16” or 8 mm steel hardware structure
through the existing .35” (9 mm) diameter mounting holes in
the module frame and then through
module mounting holes on the support structure. Tighten
the screws with adequate torque (usually 132 in-lb).
Support structure should have enough strength to keep the
mounting span. Refer to the Module Drawings for the
position of PV module mounting holes.

KDxxxGX-LPx series modules and most PV system

components have a maximum system voltage rating of 600
volts DC. Some grid feed in systems operate at or near this
voltage rating. Like other polycrystalline the PV m odules,
the open circuit voltage of the
modules increases as the ambient temperature decreases.
Maximum system voltage is computed as the sum of the
open-circuit voltage of the series-connected PV modules for
the lowest expected ambient temperature. Refer to the
National Electrical Code Article 690-7(a) for determining the

accurate prediction of module voltage under temperature
extremes.
NOTE: Install the maximum number of series connection for
the KDxxxGX-LPx series modules so that the system
voltage is less than 600 V.
NOTE: Do not connect the modules in parallel without
maximum over current protection.
NOTE: The minimum diameter that the cable can be bent
for the KDxxxGX-LPx series modules is 1.93” (49mm).
NOTE: In normal conditions, PV modules may produce
larger current and / or voltage than reported in the standard
test conditions. Therefore, when voltage evaluations for
components, capacity of conductors , size of fu ses, and siz e
of control systems connected to the module output are
determined, multiply the values of short- circ uit current (Isc)

8. GROUNDING

Before installation, contact the local code authorities to
determine the necessary grounding requirements. When
installing in US market, attach all PV module frames to an
earth ground in accordance with the National Electrical
Code (NEC) Article 250. Proper grounding is achieved by
connecting PV module frames and all metallic structural
members contiguously to one another using a suitable
grounding conductor. The grounding con ductor shall be of
copper, copper alloy or another material suitable for use as
an electrical conductor per NEC. The grounding conductor
must then make a connection to earth using a suitable earth
grounding electrode. Ensure positive electrical contact
through the anodizing on the module frame extrusion by
utilizing one of the following methods. Attach the grounding
conductor:
