Photovoltaic solar modules convert light energy to direct-current electrical
energy, and are designed for outdoor use. Proper design of support structures is
the responsibility of the system designer and installer.
Modules may be ground mounted, pole mounted, or mounted on rooftops.
Do not apply paint or adhesive to the module.
When installing modules, observe all applicable local, regional and national
codes and regulations. Obtain a building and/or electrical permit where required.
Storage Temperature: -10 C
～
40 C, Storage Hu
midity: ≤70%RH;
Modules should operate at environmental temperature of between -40 to +85
℃
. If
modules are to be installed in areas where the temperature may go outside the
above range, please consult with ET Solar before installation.
Observe the instructions and safety precautions for all other components used in
the system, including wiring and cables, connectors, DC-breakers, mounting
hardware, inverters, etc.
Use only equipment, connectors, wiring and mounting hardware suitable for use in
a photovoltaic system.
Always use the same type of module within a particular photovoltaic system.
Under normal operating conditions, PV modules will produce currents and
voltages that are different from those listed in the date sheets. The values in the
module data sheets are collected under very specific circumstances known as
Standard Test Conditions.
Short-circuit current and open-circuit voltages should be multiplied by a factor of
1.25 when determining component voltage ratings, conductor ampacity, fuse
sizes and size of controls connected to the module or system output. An
additional multiplying factor of 125 percent (80 percent de-rating) may be
applicable.
Drainage holes must not be covered with parts of the mounting system. The
junction box has a breather port which must be mounted facing downward and
cannot be exposed to the rain. The junction box should be on the higher side of
the module when it is mounted in order to orient the breather port correctly.
Do not lift the module by grasping the module's junction box or electrical leads.
Do not stand or step on module.
Do not drop the module or allow objects to fall on the module.
Do not place any heavy objects on the module.
Do not scratch the anodized coating of the frame (except for grounding
connection).
Do not scratch the glass surface.
Prior to installation, do not store modules outdoors or in a damp environment.
Inappropriate transport and installation may damage the module glass or frame.
Solar modules produce electrical energy when exposed to sunlight. DC voltages
may exceed 30V on a single exposed module.
Only connect modules with the same rated output current in series. If modules are
connected in series, the total voltage is equal to the sum of the individual module
voltages.
Only connect modules or series combinations of modules with the same voltage in
parallel. If modules are connected in parallel, the total current is equal to the sum
of individual module or series combination currents.
Bypass diodes are preassembled in each module. Do not remove these diodes.
Keep children well away from the system while transporting and installing
mechanical and electrical components.
Completely cover all modules with an opaque material during installation to
prevent electricity from being generated.
Do not attempt to disassemble the module, and do not remove any attached
nameplates or components. Doing so will void the warranty.
Do not use mirrors or other hardware to artificially concentrate sunlight on the module.
Use appropriate safety equipment (insulated tools, insulating gloves, etc)
approved for use on electrical installations.
2.1 Safety precautions for installing a solar photovoltaic system
Do not wear metallic rings, watchbands, ear, nose, or lip rings or other metallic
devices while installing or troubleshooting photovoltaic systems.
