KC-TYPE SERIES
Please read this manual carefully before
1. INT RODUCTIO N
As the world leader in high technology ceramic/silica
applications, Kyocera has stepped into the forefront in
development of mul ticrystalline solar modul es. Kyocera
began researching photovoltaics in 1975 and has
supplied many thousands of modules throughout the
world since 1978. Its years of experience and state-ofthe-art technology have produced qual ity sol ar modules
in a range of sizes to meet the energy needs of the
growing solar mark et.
2. POWER MODULES
Kyocera "KC" series modules come in v arious sizes to
satisfy a full range of applicati ons. E ac h module is made
of multi - crystalli ne cells manufac tured by the "casting"
method. These cel ls c ov er nearly 100% of t he modul e's
surface. To protect the cells from the most severeenvironmental conditions, they are encapsulated
between a tempered glass cover and an EVA pottant
with PVF back sheet. The entire lami nate is installed in
an anodized alum inum f ram e for structural strength and
ease of instal lation.
3. APPLICATIONS
Kyocera modules are a reliable, virtually maintenance
free power supply, designed to operate efficiently in
sunlight. Kyocera solar modules are ideal for charging
storage batteries used to power remote homes,
recreational vehicles, boats, telecommunication systems
and other elect r ic generation application.
4. MOUNTING SITE SELECTION
The solar modules should be mounted i n a location
wh e r e they will re c e ive ma ximum sunlight th r oughout the
year. In the Nor thern Hemisphere, the modules should
face south, and in the Southern Hemisphere, the
modules should face north. Modules facing 30 degr ees
away from true South (or North) will lose approximately
10 to 15 per cent of their power output . If t he module
faces 60 degrees away from true South (or Nor th), the
power loss will be 20 to 30 per cent. When choosing a
site, avoid trees, buildings or obstructions which could
cast shadows on the solar modules especially during the
winter mont hs when the arc of the sun is lowest over the
horizon.

5. MODULE TILT ANGLE
Solar m odules produce the most power when they are
pointed directly at the sun. For installations where the
solar modules are mounted to a permanent structure,
the solar modules should be tilted for optimum winter
perform ance. As a rule, if the system power production
is adequate in the winter, it will be satisfactory during the
rest of the year. The module tilt angle is measured
between the solar modules and the ground (Figure 1) .
6. MOUNTING THE MODULE
The frame of each module has fourteen 7 mm Ú
diamet er mounting holes (Fi gure 2). These are used to
secure the modules to the supporting structure. The
example of a ground mounted structure is shown in
Figure 3. The four holes close to the corners of the
module are most often used for mounting. Clearance
between the module frame and the mounting surface
may be required to prevent the junction box from
touching the surf ace, and to ci rculat e cooli ng air around
the back of the module. In case the modules will be
mounted on the roof or wall of a building, the standoff
method or t he r ac k method are recommended.
STANDOFF: The modules are supported par allel t o the
surface of the building wall or roof. Clearance between
the module frames and surface of the wall or roof is
required to pre- vent wiring dam age and to allow air to
circul ate behind the m odule.
The recommended standoff height is 4.5 i n.

RACK: The supporti ng fram e is used to mount modules
at correct t ilt angles. T he modules are not designed for
integral m ounti ng as part of a r oof or wall. The mounti ng
design may have an impact on the fire resistance.

7. WIRING
Most of the larger KYOCERA P OWE R M ODULES use
the "G" or " M " type junction box. This box, on the back
side of the module, is weatherproof and is designed to
be used with standard wiring or conduit connecti ons.
Wiring m ethods should be in accordance to the NEC
(National E lectric al Code). Bypass diodes and cable
clamps are included with each module when shipped
from the factory.
A. Open the "G" or "M" box cover by loosening the
screws in the cover . (Figure 4 and 5)
B. The wire ty pically used to interconnect the solar
modules should be single or two conductor, from 10
AW G(5.26 mm²) up to 14 AWG(2. 08 mm²) gauge
stranded copper wire, i n a " S UNLIGHT RESIS TANT"
jacket UF c able. This cable is suitable for appli c ations
where wiring is exposed to t he direct rays of the sun.
The maximum and minimum diameter of the cabl e that
may be used with the cable connector are 8 mm and 6
mm r espect ively. (Figure 6)
C. Using a flat blade screwdriver, remov e only the
appropriate "K NOCK-OUTS" from the sides of the
"G" or "M" box. (Figure 7 and 8)
