1. INTRODUCTION
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.
2. APPLICATIONS
KC series modules are a reliable, virtually
maintenance-free direct current (DC) power source,
designed to operate most efficiently in sunlight. KC series
modules are ideal for powering remote homes, water
pumps, utility grid-tie, telecommunication systems and
many other applications either with or without the use of
storage batteries.
3. WARNINGS SAFETY
Solar 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 to avoid shocks or burns.
Do not touch live terminals with bare hands. Use insulated
tools for electrical connections.
PERMIT
Before installing your solar system, contact local
authorities to determine the necessary permit,
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 KC series modules are quite rugged, the
glass can be broken (and the module will no longer
work properly) if it is dropped or hit by tools or other
objects.
Sunlight shall not be concentrated on the module.
The module frame is made of anodized aluminum, and
therefore corrosion can occur if the module is subject
to a salt-water environment with contact to a rack of
another type of metal. (Electrolysis Corrosion) If
required, PVC or stainless steel washers can be
placed between the solar module frame and support
structure to prevent this type of corrosion.
KC series module(s) frame must be attached to a
support structure by one of the methods described in
Section 6, Installing KC series module(s).
Module support structures that are to be used to
support KC series module(s) should be wind rated and
approved for use by the appropriate local and civil
codes prior to installation.
FIRE RATING
KC series modules are comprised of a glass front
surface, polyvinyl fluoride (PVF) backskin and possess
a Class C fire rating.
GROUNDING
Refer to “Grounding” section.
INSPECTION
Follow the requirements of applicable local and
national electrical codes.
BATTERY
When solar modules are used to charge batteries, the
battery must be installed in a manner, which will
protect the performance of the system and the safety
of its users. Follow the battery manufacturers
guidelines concerning installation, operation and
maintenance recommendations. In general, the
battery (or battery bank) should be away from the main
flow of people and animal traffic. 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 the purpose.
4. SITE SELECTION
In most applications, KC series 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 the solar modules especially

Summary

Applications of Kyocera KC Series Modules

Warnings and Safety Precautions

Permit and Installation Requirements

Contact local authorities for necessary permits, installation, and inspection requirements before system installation.

Safe Installation and Operation Practices

Systems must be installed by qualified personnel. Avoid stepping on modules and use insulated tools for electrical connections.

Module Tilt Angle

Tilt Angle for Grid Tie Installations

For grid tie installations, tilt modules at site latitude for highest annual energy output.

Installing Kyocera KC Series Modules

Building Attached Module Installation

Modules mounted parallel to building surfaces require clearance for wiring damage prevention and air circulation.

Free Standing Module Installation

Free standing structures use correct tilt angles; mounting design may impact fire resistance.

Module Attachment Methods

Standard hardware, clamping, or other certified methods are used for module attachment to support structures.

Module Wiring Safety

Do not make connections under load. Maximum system voltage is 600 VDC.

Grounding Procedures

Grounding Methods

Attach grounding conductor via designated holes, conductive structure, or multiple screws for proper grounding.

Bypass Diodes

Bypass Diode Functionality

Provide a low-resistance path around shaded cells to minimize module heating and array current losses.

Maintenance Recommendations

Annual Maintenance Checks

Inspect wiring and tighten mounting hardware annually to ensure optimal performance and prevent damage.
