3.0 Electrical Characteristics
3.0 Electrical Characteristics3.0 Electrical Characteristics
3.0 Electrical Characteristics
The module electrical ratin s are measured under Standard Test Conditions (STC) of 1 kW/m²
irradiance with AM 1.5G spectrum and a cell temperature of 25º C. YURAKU modules deliver
specific electrical characteristics.
A photovoltaic module may produce more current and/or volta e than reported at STC.
Sunny, cool weather and reflection from snow or water can increase current and power output.
Therefore, the values of Isc and Voc marked on the module should be multiplied by a factor of
1.25 when determinin component volta e ratin s, conductor ampacities, fuse sizes, and size of
controls connected to PV output. An additional 1.25 multiplier may be required by the NEC for
sizin fuses and conductors as described in the NEC Section 690-8.

To avoid electrical shock, round the frame of the module or array before wirin the circuit
usin a roundin method that meets NEC requirements for roundin solar electrical systems.
YURAKU recommends the followin two methods of roundin the module frame. Fi ure 2 is
for customer reference.
1) Usin an equipment round conductor with stainless steel hardware at one of the two
desi nated Φ3.8 roundin holes on the module frame. If a equipment round conductor
lar er in diameter than #10 AWG is necessary, a roundin lay-in lu is required. A thread-
formin 8-18 stainless steel screw is required when usin a self-drillin type screw to make the
frame round connection. Please refer to NEC Article 690 on roundin PV arrays for specific
requirements.
2) YURAKU modules can be rounded usin third-party roundin washer or clip systems
provided they have been tested and certified to meet UL 467 and UL 1703 requirement for
bondin / roundin systems and are installed accordin to the manufacturer’s specified
instructions.

• The modules may be wired in series to produce the desired volta e output. Do not
exceed the maximum system volta e indicated in the specification sheet of the modules.
• The modules may be combined in parallel to produce the desired current output. Each
series strin or module may be required to be fused prior to combinin with other strin s.
Please refer to the NEC Article 690 for additional fusin requirements.
• Modules shall not be wired in parallel without maximum over current protection.
• These modules contain factory installed bypass diodes. If these modules are incorrectly
connected to each other, the bypass diodes, cable, or junction box may be dama ed.
• In order to minimize volta e sur es which could be induced by indirect li htnin strikes,
DC cables of the same strin should be bundled to ether so that loops are kept as small
as possible. Strin confi urations should be checked before system commissionin . If the
open circuit volta e (Voc) and the short circuit current (Isc) deviates from the
specifications, this could indicate a confi uration fault. Correct DC polarity should be
observed at all times.

YURAKU modules should be mounted in locations that meet the followin requirements:
Operating Temperature:
All YURAKU modules must be mounted in environments that ensure YURAKU modules will
operate within the followin maximum and minimum operatin temperatures:
Max. Operatin Temp. +85°C, +185°F
Min. Operatin Temp. -40°C, -40°F
Care should be taken to provide adequate ventilation behind the modules, especially in hot
environments.

Design Strength:
YURAKU modules are desi ned to meet a maximum positive (or upward, e. . wind) desi n
pressure of 2400 Pa and ne ative (or downward, e. . static load) desi n pressure of 5400 Pa
when mounted in one of the mountin confi urations specified in Section 6.2.
A desi n stren th of 2400 Pa corresponds approximately to a wind speed of 125 mph.
When mountin modules in snow-prone or hi h-wind environments, special care should be
taken to mount the modules in a manner that provides sufficient desi n stren th while meetin
local code requirements.
Excluded Operating Environments:
Certain operatin environments are not recommended for YURAKU modules and are excluded
from the YURAKU Limited Warranty for these modules.
• No YURAKU module should be mounted at a site where it may be subject to direct
contact with salt water. Recommended distance from the sea: 1.600 feet.
• YURAKU modules with an anti-reflective coatin on the lass should not be mounted in
basic environments (those which have a PH balance equal to or reater than 7). Basic
environments de rade the coatin , reduce module ener y ain and may cause a non-
uniform appearance. This is not a concern in most areas because most outdoor
environments are acidic and therefore do not pose a problem, but YURAKU recommends
that the site be checked before mountin the modules, especially in coastal settin s.
• Where YURAKU module could be exposed to sulfur or other corrosive chemicals, such as
near sulfur sprin s or volcanoes because of the dan er of corrosion.

In order to prevent water from enterin the junction box, which could present a safety hazard,
modules should not be mounted such that the front/top lass faces downward (e. ., on a
trackin structure that positions the modules with the junction box facin skyward durin sleep
mode).
Clearance between the module frames and structure or round is required to prevent wirin
dama e and allows air to circulate behind the module.
The module is only UL Listed for use when its factory frame is fully intact. Do not remove or alter
the module frame. Creatin additional mountin holes may dama e the module and reduce the
stren th of the frame.
For roof mountin , the assembly is to be mounted over a fire resistant roof coverin rate for the
application, and any slope less than 5 in/ft (127/305 mm) required to maintain a fire class
ratin .

Modules may be mounted usin the followin methods only:
1) Frame Holes: Secure the module to the structure usin the factory mountin holes. Four 8mm
stainless steel bolts, with nuts, washers, and lock washers are recommended per module. Refer
to Table 2 for the module dimensions and hole locations. This method has been certified by a
third-party or anization accordin to UL 1703.
2) Pressure Clamps or Clips: Mount the module with the clips on the side frame of the module.
The side frames are attached to the lon er sides of the module. The centerline of the clips
should be 6 -15 from the end of the side frame. Installers should ensure the clamps are of
sufficient stren th to allow for the maximum desi n pressure of the module. Clips and clamps
are not provided by YURAKU.
3) End Mount: End mountin is the capture mountin of the len th of the module’s end frame to
a supportin rail. The end frames are on the shorter dimensions of the module.
The end-mountin rail and clips or clamps must be of sufficient stren th to allow for the
maximum desi n pressure of the module. Verify this capacity with the mountin system vendor
before installation.

Inspect all modules annually for safe electrical connections, sound mechanical connection, and
freedom from corrosion. Periodically clean the module surface with water and a soft cloth or
spon e. Fin erprints may be removed with standard lass cleaner. Do not use harsh cleanin
materials such as scourin powder, steel wool, scrapers, blades, or other sharp instruments to
clean the lass surface of the module. Use of such materials will invalidate the product warranty.
