GENERALINFORMATION
GeneralSafety
•Do not attempts to install, wire, operate or maintain the modules before reading through the manual.
•The installation should only be carried out by qualified licensed personnel.
•When installing the system, abide to all local, regional and national statutory regulations. Contact your local
authorities to determine the required permits before installation.
•One single module may generate more than 30V DC when exposed to direct sunlight. Contact with a DC voltage of
30V or more is potentially hazardous.
•Do not disconnect under load.
•Modules are designed for outdoor use. Modules can be ground mounted, mounted on rooftops, vehicles or boats.
•Do not use mirrors or other magnifiers to concentrate sunlight onto the modules.
•Do not apply paint or adhesive to the module top surface.
•Only use equipment, connectors, wiring and support frames suitable for solar electric systems.
HandlingSafety
•Do not lift the module by grasping the module’s junction box or electrical leads.
•Do not stand or step on the module.
•Do not drop the module or allow objects to fall on the module.
•Do not disassemble the modules or remove any part of the module.
•Do not damage or scratch surfaces or back side of the module.
•Do not drill holes in the frame. This may compromise the frame strength and cause corrosion of the frame.
•Do not scratch the anodized coating of the frame (except for grounding connection). It may cause corrosion of the
frame or compromise the frame strength.
•Work only under dry conditions, and use only dry tools. Do not handle panels when they are wet unless wearing
appropriate protective equipment.
InstallationSafety
•Never open electrical connections or unplug connectors while the circuit is under load.
•Do not use a module with broken glass or torn substrate as it may cause electrical shock when contacting with other
module frames and surfaces.
•To avoid the hazard of electrical shock and injury, cover the module’s surface with an opaque material (cardboard)
during installing or working with a module or wiring.
•Use properly insulated tools and appropriate protective equipment to reduce risk of electric shock. Wear suitable
protection to prevent direct contact with 30V DC or greater.
•Do not handle the modules during periods of high wind, thunderstorm, blizzard, heavy snow or any other severe
weather conditions.
•Do not install or electric connect wet modules.


•Do not wear metallic rings, watchbands, ear, nose, lip rings or other metallic objects
•Abide to the safety regulations for all other system components, including wires and cables, connectors, charging
regulators, inverters, storage batteries, rechargeable batteries, etc.
•Only use connectors to connect modules to form a string, or connect to another device. Removing the connectors
will lead to the warranty becoming void.
•Contact with electrically changed parts of the panels, such as terminals, can result in burns, sparks and lethal shock
whether or not the panel is connected.
•Do not touch the PV module unnecessarily during installation. The glass surface and the frame may be hot; there is a
risk of burns and electric shock.
•Avoid exposing cables to direct sunlight in order to prevent their degradation.
•Keep children well away from the system while transporting and installing mechanical and electrical components.
FireSafety
•Consult your local authority for guidelines and requirements for building or structural fire safety.
•Roof constructions and installations may affect the fire safety of a building; improper installation may create hazards
in the event of a fire.
•The modules have been rated Fire Class C, and are suitable for mounting onto a Class A roof. A fire-resistant-covering
roof rated for such an installation is required for rooftops applications.
•It may be necessary to use components such as earth ground fault circuit breakers, fuses and circuit breakers.

OperationConditions
Topray Solar crystalline solar modules are designed for operations under the following conditions:
AmbientTemperature:40°Cto+40°C
StorageTemperature:20°Cto+40°C

MechanicalLoadPressure:5400Pa(Below112.78lb/ft2)
The mechanical load bearing (include wind and snow loads) of the module is based on the mounting methods. Installer
must be responsible for mechanical load calculation according to the system design.
SiteSelection
Select a suitable location for installing the modules. In most applications, Topray Solar crystalline solar modules should be
installed in a location where they will receive maximum sunlight throughout the year. The modules should be facing south
in northern latitudes and north in southern latitudes.
The module will have loss of power output of 10%-15% if the unit is greater than 30 degrees from true south/north. The
module will have loss of power output of 20%-30% if the unit is greater than 60 degrees from true south/north.
The module should not be shaded at any time. When choosing a site, avoid trees, buildings or obstructions, which could
cast shadows on the modules especially during the winter months when the arc of the sun is lowest over the horizon.
Shading causes loss of output, even though the factory fitted bypass diodes of the modules will minimize any such loss.
For detailed information on the best installation angle, refer to standard solar photovoltaic installation guides or consult a
reputable solar installer or systems integrator.
•Do not install the modules near naked flame or flammable materials.
•Do not install the modules in a location where it would be immersed in water or continually exposed to water from a
sprinkler or fountain etc.
•Do not install the modules in a marine environment and/or area where salty wind hit directly.
•Do not install the modules in corrosive environment, such as corrosive salt area or sulfurous area, etc.
TiltAngle
Topray Solar crystalline solar modules produce the most power when they are facing sunlight directly. The module tilt
angle is measured between the solar module and the ground (See Figure 1). The modules connected in series should be
installed at same orientation and angle. Different orientation or angle may cause loss of output power due to difference of
amount of sunlight exposed to the module. Optimal tilting of modules is almost the same as the latitude of installation
location.


Figure1.ModuleTiltAngle
For installations where the modules are attached to a permanent structure, the modules should be tilted for optimum
winter performance. As a rule, if the system power production is adequate in winter, it will be satisfactory during the rest
of the year.
Topray Solar recommends a minimum installation angle of 10 degrees because this enables dust to be washed off by rain
or dew for greater light intensity. This will also improve ventilation and thus output, because module performance is
better at a lower temperature.

Topray Solar crystalline solar modules should be installed by qualiĮed professionals only. The process involves electricity
and can be dangerous if the installing personnel are not familiar with the appropriate safety procedures.
Topray Solar crystalline solar modules are qualiĮed for class A: Hazardous voltage (IEC 61730: higher than 50V
DC; EN 61730: higher than 120V), hazardous power applications (higher than 240W) where general contact access is
an pated (Modules qualiĮĞĚ for safety through EN IEC 61730-1 and -2 within this application class are considered to
meet the requirements for Safety Class II).
Several modules are connected in series and then in parallel to form a PV array, especially for app ons with a high
ope voltage. Do not use modules of Ěŝīerent conĮgur ns in the same system. If modules are connected in series,
the total voltage is equal to the sum of individual voltages. For ons requiring high currents, several photovoltaic
modules can be connected in parallel; the total current is equal to the sum of individual currents.
The maximum number of modules connected in series = Vmax system / Voc at STC. When designing the PV system, please
always take into conside the n of the voltage under diīerent temperatures (please check the
temperature coeĸcients of the modules, the Voc of the modules will be rise when the temperature drops).
Topray Solar crystalline solar modules electrical are measured under Standard Test Condi ons (STC, irradiance of
1000W/m2, AM 1.5 spectrum, cell temperature 25°C /77°F). Under normal outdoor cond , a module may produce
more current or voltage than its STC rated power. Accordingly, during system design, Short-Circuit Current and Open-
Circuit Voltage should be mu plied by a factor of 1.25 to determine component voltage conductor ampacity, fuse
rng and the size of the controls connected to the modules or system output.
Tables 4, 5, 6, 7, 8,below are the major electrical chara of Topray Solar crystalline solar modules at STC appear on

Topray Solar crystalline solar modules has two 4mm2diameter type standard 90°C sunlight resistant output cables each
terminated with plug & play connectors. This cable is suitable for applica ons where wiring is exposed to the direct rays of
the Sun. For a series electrical connec on, connect posi (+) connector of ĮƌƐƚ module to the (-) connector of
the second module.
All wiring should be completed in accordance with all applicable state and local electrical codes. During system design,
Short-Circuit Current (Isc) and Open-Circuit Voltage (Voc) should be mul plied by a factor of 1.25 to determine component
voltage , conductor ampacity, fuse ra ng and the size of the controls connected to the modules or system output.
Topray Solar suggests that every series module string should be fused prior to be connected with other strings. Please
refer to the applicable regional and local codes for addi fuse requirements. When necessary, please install blocking
diodes to protect modules or system been damaged by reverse current.
Do not short the po and the nega ve of a single module. Do not disconnect under load. Be sure connectors have no
gap between the insulators. A gap can cause Įre hazard and/or danger of an electrical shock.
All Topray Solar crystalline solar module frames and mo racks must be properly grounded in accordance with the
appropriate na onal electrical code. Proper grounding is achieved by conn the module frame(s) and
structural members con uously one to another using a suitable grounding conductor. Holes provided for this purpose on
the module frame are d in chart 4. The grounding conductor or strap may be copper, copper alloy, or other
material acceptable for use as an electrical conductor per resp nal Electrical Codes. The grounding conductor
must then make a conn on to earth using a suitable earth ground electrode.

JunctionBoxwithBypassDiodes
Partial shading of an individual module can cause a reverse voltage across the shaded module. Current is then forced go
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 SPV module, thereby minimizing module heating and array current losses.
Each Topray Solar crystalline solar module has a TÜV approved junction box with 3 to 6 bypass diodes already installed.


MAINTENANCE
Topray Solar crystalline solar modules require minimal maintenance. Given a sufficient tilt (at least 15°), it is not generally
necessary to clean the modules (rainfall will have a self cleaning effect). Regular maintenance is required to keep modules
clear of snow, bird droppings, seeds, pollen, leaves, branches, dust and dirt spots. When there is a noticeable buildup of
soiling deposits on the module surface, wash the PV array using water without cleaning agents and a gentle cleaning
implement (a sponge), during the cool of the day. Dirt must never be scraped or rubbed away when dry, as this will cause
micro-scratches. If snow is present, a brush with soft bristles can be used to clean the surface of the module.
Once a year the modules need to be inspected for tightness of screws securing the modules to the racking frame. The
general condition of the wiring needs to also be inspected. Loose hardware could result in damage to the panel. Strong
wind conditions could loosen the mounting devices.
Do not change the PV components (diode, junction box, plug connectors).
If you need electrical or mechanical inspection or maintenance, it is recommended to have a licensed, authorized
professional carry out the inspection or maintenance to avoid hazards of electric shock or injury.
WARNING:Foranyelectricalmaintenance,thePVsystemmustfirstbeshutdown.Impropermaintenancecancause
lethalelectricshockand/orburns.
