1.INTRODUCTION
This manual contains information of electrical and mechanical installation and safety
information which you should know before using photovoltaic module ND-L3E1U.
The information in this manual is described on the basis of Sharp’s knowledge and
experience. But such information and suggestions do not constitute a warranty.
Sharp Corporation reserves the right to make changes to the product, specifications, or to
the manual without prior notice.
2.INSTALLATION
Back view of the module is shown in Fig.1. Each module has ten 9.0 mm diameter
mounting holes. These are used to fix the modules to supporting structure. For
withstanding load 2400Pa, module shall be fastened with 4-C holes with M8 bolts.
When connecting the modules to a battery or to other modules, you must carefully
observe correct cable connection polarity as shown in Fig.2. If not connected correctly,
the bypass diode could be destroyed. This will void your warranty.
Each photovoltaic module has a hole in the side frame for installation of a bolt, a nut and
washer. The ground wire lug connector can be attached to each photovoltaic module
using provided bolts, nut and washer as shown in Fig.3. The ground wire shall be not
smaller than No.14 AWG (2.1mm2).
3.MOUNTING STRUCTURE
An example of acceptable mounting structure is shown Fig.4.
4.ELECTRICAL RATINGS
Rated electrical characteristics are within ±10 percent of the indicated values of Isc, Voc
and Pmax under standard test conditions (irradiance of 100 mW/cm2, AM 1.5 spectrum,
and a cell temperature of 25 ℃(77°F)).
The above electrical characteristics are based on the results of out going test. The
warranty condition is specified in the warranty card separatly issued.
Maximum Power (Pmax) 123.0 W
Open-Circuit Voltage (Voc) 21.3 V
Short-Circuit Current (Isc) 8.12 A
Operating Voltage (Vpmax) 17.2 V
Current at Vpmax (Ipmax) 7.16 A
Maximum System Voltage 600 V
Series Fuse 15 A
The above electrical characteristics are based on the results of out going test.
Please do not expose solar module to sunlight concentrated with mirrors, lenses or similar
means.

Under normal conditions, a photovoltaic module may experience conditions that produce
more current and/or voltage than reported at Standard Test Conditions.
Accordingly, the values of Isc and Voc marked on UL Listed modules should be multiplied
by a factor of 1.25 when determining component voltage ratings, conductor capacities,
fuse sizes and size of controls connected to the module output. Refer to Sec. 690-8 of the
National Electric Code for an additional multiplying factor of 125 percent ( 80 percent of
rating ) which may be applicable.
Please refer to Section 690-8 of the National Electrical Code for an additional multiplying
factor of 1.25 which may be applicable.
In the coverage of Canadian UL listing, installation shall be in accordance with CSA C22.1,
Safety Standard for Electrical Installations, Canadian Electrical Code, Part 1.
5.CAUTION
(1) Never touch the end of output cables with bare hands when the module is irradiated.
Cover the surface of module by sufficiently thick cloth or something suitable to
prevent incident light, and handle the wires with rubber-gloved hands not to receive
electric shock.
(2) Do not wear metallic jewelry which may become cause of electric shock during
installation.
(3) Consult the government office concerned for permit installation and inspection
requirement.
(4) Install modules and ground frames in accordance with applicable law of each country.
(5) Product should be installed and maintained by qualified personnel.
(6) Do not drop tools or hard things on the glass of solar module.
(7) Do not scratch the back film by hard things.
(8) When part of solar module is shadowed, hot spot may be caused. Therefore do not
shadow cells.
(9) Do not pour chemicals on modules when cleaning.
(10) Keep children away from modules.
