be broken (and PV module will no longer work properly) if it is
dropped or hit by tools or other objects.
・
PV module frame is made of anodized aluminum, and therefore
corrosion can occur if PV 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.

1. INTRODUCTION
FIRE RATING
As the world leader in development and application of high technology
ceramic/silica materials, Kyocera offers a wide range of highly efficient
and reliable crystalline silicon solar photovoltaic (PV) power modules.
Kyocera began to extensively research PV technology in 1975 and
commenced manufacturing operations in 1978. Since then, Kyocera
has supplied millions of cells and modules throughout the world. With
years of experience and state-of-the-art technology, Kyocera provides
the highest quality PV power modules in a range of sizes designed to
meet the requirements of the most demanding energy and power users
worldwide.
・In case of roof installation, PV module assembly shall be mounted
on a fire resistant roof covering rated for the application. KD series
modules are comprised of a glass front surface, polyethylene
terephthalate (PET) back sheet with a Class C fire rating.
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.
2. POWER MODULES
Kyocera PV power modules consist of a series of electrically
interconnected crystalline silicon solar cells, which are permanently
laminated within a pottant and encapsulated between a tempered glass
cover plate and a back sheet. The entire laminate is secured within an
anodized aluminum frame for structural strength, ease of installation,
and to protect the cells from the most severe environmental conditions.
3. APPLICATIONS
Kyocera PV modules are a reliable, virtually maintenance-free direct
current (DC) power source, designed to operate at the highest level of
efficiency. Kyocera PV modules are ideal to remote homes,
recreational vehicles, water pumps, telecommunication systems and
many other applications either with or without using storage batteries.
5. SITE SELECTION
In most applications, Kyocera modules should be installed in a location
where they will receive maximum sunlight throughout the year. In the
Northern Hemisphere, 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 power 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 winter season when the arc of the sun is lowest over the horizon.
4. 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, PV 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 PV modules for solar concentration.
6. MODULE TILT ANGLE
WARNING
Kyocera modules produce bigger power when they are pointed directly
at the sun. For stand alone installations PV modules should be tilted for
optimum winter performance. As a general rule, if the system power
production is adequate in the winter, it will be satisfactory during the
rest of the year. PV module tilt angle is measured between PV
modules and the ground. Refer to the recommended module tilt angle
table for your site.

NOTE: MAXIMUM SYSTEM VOLTAGE 600VDC.
11. BYPASS DIODES
Partial shading of an individual module in a source circuit string (i.e. two
or more modules connected in series) can cause a reverse voltage
across the shaded cells within the module. Module output current is
then forced through the shaded area by the remaining illuminated cells
and other PV modules in series with the partially shaded module(s).
The current forced through the shaded cells within PV module (or
modules) causes additional module heating and severe loss of power.
The purpose of bypass diodes is to provide a low-resistance current
path around the shaded cells, thereby minimizing PV module heating
and array current losses.
KD series modules and most PV system components have a maximum
system voltage rating of 600 volts DC. Some grid-tie systems operate
at or near this voltage rating. Like other polycrystalline solar modules,
the open circuit voltage of the KD series module 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 maximum number of KD series modules that can be
placed in series. Temperature coefficients, specific to the module of
use, can be used to provide the most accurate prediction of module
voltage under temperature extremes.
NOTE: Install the maximum number of series connection for the KD
series PV modules so that the system voltage is less than 600V.
NOTE: In normal conditions, PV modules may produce bigger current
and/or voltage than reported in the standard test conditions. Therefore,
when voltage evaluations for components, capacity of conductors, size
of fuses, and size of control systems connected to the module output
are determined, multiply the values of short- circuit current (Isc) and
open-circuit voltage (Voc) that are marked in KD series modules by the
factor of 1.25. Refer to Section 690-8 of the National Electrical Code for
an additional multiplying factor of 1.25 which may also be applicable.
PV modules employ bypass diodes that have:
・
・
Rated Average Forward Current [IF(AV)] Above maximum system
current at highest PV module operating temperature.
Rated Repetitive Peak Reverse Voltage [VRRM] Above maximum
system voltage at lowest PV module operating temperature.
12. MAINTENANCE
Kyocera PV modules are designed for long life and require very little
maintenance. Under most weather conditions, normal rainfall is
sufficient to keep the module glass surface clean. If dirt build-up
becomes excessive, clean the glass surface only with a soft cloth using
mild detergent and water. USE CAUTION WHEN CLEANING THE
BACK SURFACE OF PV MODULE TO AVOID PENETRATING THE
BACK SHEET. PV modules that are mounted flat (0°tilt angle) should
be cleaned more often, as they will not "self clean" as effectively as
modules mounted at a 15°tilt or greater. Once a year, check the
tightness of terminal screws and the general condition of the wiring.
Also, check to be sure that mounting hardware is tight. Loose
connections may result in a damaged PV module or array.
9. GROUNDING
Before installation, contact the local code authorities to determine the
necessary grounding requirements. Attach all PV module frames to an
earth ground in accordance with the National Electric 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 conductor 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 PV module
frame extrusion by utilizing one of the following methods. Attach the
grounding conductor:
13. SPECIFICATIONS
Under certain conditions, a photovoltaic module may produce more
voltage and current than reported at Standard Test Conditions (STC).
Refer to Section 690 of the National Electrical Code for guidance in
series string sizing and choosing overcurrent protection.
(1)to one of the 9mm (0.35”) diameter holes marked “ground” using
5/16” stainless steel hardware. Wrap conductor around bolt. Tighten
the screws with adequate torque (usually 132 in-lb). Avoid direct
contact of copper ground conductor to aluminum frame.
(2)to a ground lug (manufacture : ILSCO, model : GBL-4DBT). Tighten
the screws with adequate torque (usually 62 in-lb). Use #10-32
stainless steel hardware to attach the lug to the module frame by the
torque of 40 in-lb. A stainless steel star washer,
positioned between the lug and the anodized surface of the frame,
must be employed to break through the anodized layer of the frame
extrusion and electrically connect the ground lug to the conducting
aluminum frame material.

In systems utilizing a battery, blocking diodes are typically placed
between the battery and PV module output to prevent battery from
discharging at night. Kyocera PV modules are made of polycrystalline
cells with high electrical “back flow” resistance to nighttime battery
discharging. As a result, Kyocera PV modules do not contain a
blocking diode when shipped from the factory. Most PV charge
regulators and inverter incorporate nighttime disconnect feature,
however.
