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/ft

)
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.
