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.
