9. GROUNDING
We recommend you attach all module frames to an earth ground. Attach a
separate ground wire to one of the holes marked ‘ground’ on the module
frame with a screw and bonding or external tooth washer. This is to ensure
positive electrical contact with the frame. The racks must also be
grounded unless they are mechanically connected by nuts and bolts to the
grounded modules. The array frame shall be grounded in accordance with
NEC Art 250.
10. BLOCKING DIODES
Blocking diodes are typically placed between the battery and the PV
module output to prevent battery discharge at night. Kyocera modules are
made of polycrystalline cells with high electrical “back flow” resistance to
nighttime battery discharging. As a result, KYOCERA modules do not
contain a blocking diode when shipped from the factory. Most PV charge
regulators do have nighttime disconnect feature, however.
11. BYPASS DIODES
Partial shading of an individual module in a 12 volt or higher source circuit
string (i.e. two or more modules connected in series) can cause a reverse
voltage across the shaded module. Current is then forced through the
shaded area by the other modules.
When a bypass diode is wired in parallel with the series string, the forced
current will flow through the diode and bypass the shaded module, thereby
minimizing module heating and array current losses.
For 12-volt systems and higher: Each module junction box has a diagram
illustrating the proper orientation of the bypass diode installed between two
of the terminal screws. When
individual series strings of solar modules are
connected together in parallel, bypass diodes should be used in each
modules junction box.
Diodes that are used as bypass diodes must:
・
Have a Rated Average Forward Current [I
F(AV)
]
Above
maximum
system current at highest module operating temperature.
・
Have a Rated Repetitive Peak Reverse Voltage [V
RRM
]
Above
maximum system voltage at lowest module operating temperature.
12. MAINTENANCE
Kyocera 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
THE MODULE TO AVOID PENETRATING THE PVF SHEET. 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 will result in a damaged module or
array.

NOTES
・
The electrical characteristics are indicated values of Pmax under
standard test conditions (irradiance of 1KW/m
2
, AM 1.5 spectrum,
and cell temperature of 25
℃
).
・
Under certain conditions, a photovoltaic module is likely to produce
more current and / or voltage than reported at standard test
conditions. Accordingly, the values of Isc and Voc marked on this
module should be multiplied by a factor of 1.25 when determining
component voltage ratings, conductor ampacities, fuse sizes, and
sizes of regulators which are connected to the PV output. Refer to
Section 690-8 of the National Electrical Code for an additional
multiplying factor of 1.25 which may also be applicable.
