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. POWER MODULES
Kyocera power modules consist of aseries 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 modules are a reliable, virtually maintenance-free direct
current (Oe) power source, designed to operate at the highest level of
efficiency. Kyocera modules are ideal to remote homes, recreational
vehicles, water pumps, telecommunication systems and many other
applications elther with or without using storage batteries.
4. WARNINGS AND SAFETY PRECAUTION
PV modules generate electricity when exposed to light. Arrays of many
modules can cause lethai 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.
00
not touch live terminals
with bare hands. Use insulated tools for electrical connections.
00
not
use these modules for solar concentration.
PERMIT
Before installing your PV system, contact local authorities to
determine the necessary permitting, 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.
00 not step on a PV module.
Although Kyocera modules are quite durable, t r
•
"lass 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 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.
KO se ries module frames must be attached to a support structure
using
'1."
or M6 stainless steel screw in a minimum of four (4)
places symmetrical on PV module. The stainless steel screw used
for fixing the module frame should secure with an applied torque of
6 foot-pounds (8 Newton-meters).
Module support structures to be used to support PV modules
should be wind rated and approved by the appropriate local and
civil codes prior to installation.
00
not expose the back of the module to direct sunlight.
FIRE RATING
In case of roof installation, PV module assembly shall be mounted on
a fire resistant roof covering rated for the appllcatlon. KO 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 weil 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.
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 modulesespecially
during winter season when the arc of the sun is lowest over the horizon.
6. MODULE TIL T ANGLE
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.

For grid tie installations where the solar 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.
7. INSTALLING KD SERIES MODULES
The minimum spacing of 0.6 in. (15 mm) is required between PV
module and the mounting surface around the perimeter of PV module.
