GENERALINFORMATION
GeneralSafety
•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.
HandlingSafety
•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.
InstallationSafety
•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.
2
•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.
FireSafety
•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.

MECHANICALINSTALLATION
OperationConditions
Topray Solar crystalline solar modules are designed for operations under the following conditions:
AmbientTemperature:40°Cto+40°C
StorageTemperature:20°Cto+40°C
OperatingTemperature:40°Cto+85°C
Humidity:85RH%
MechanicalLoadPressure:5400Pa(Below112.78lb/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.
SiteSelection
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.
TiltAngle
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.

Figure1.ModuleTiltAngle
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 can be mounted by using the following methods:
- Modules can be mounted by using moun ng holes at the module frame with corrosion-proof screws.
- Modules can be mounted by using suitable module clamps on the long side of the module frame.
- Modules can be mounted by using suitable module clamps on the short side of the module frame.
Pleased be noted that Topray solar will not provide related BOS components, the system installer or trained professional
personnel must be responsible for the PV system’s design, inst
system.
A) Module installed with moun ng holes
The frame of each module has 8 ng holes (Length* Width: 14mm*9mm) used
rail using M8 corrosion-proof screws together with spring
washers and ŇĂƚ washers. Use 4 or 8 symmetrical moun ng holes on the module for diīerent loads as pointed by the red

Figure3.ModuleInstalledwithMountingHoles
B) Clamping installation – On the long side of the frame
Use a certain number of clamps to fix Topray Solar crystalline solar modules on the mounting rail. The module clamps
should not come into contact with the front glass and must not deform the frame. Be sure to avoid shadowing effects
from the module clamps. The module frame is not to be modified under any circumstances.
When choosing this type of clamp-mounting method, please be sure to use at least four clamps on each module, two
clamps should be attached on each long side of the module. Depending on the local wind and snow loads, additional
clamps may be required to ensure the module can bear the load. The mounting rail and the clamps center line can be
moved along on the long side of the frame but recommended to be within the red arrow area in Figure 4 (area K). Please
