V) MECHANICAL INSTALLATIONS
a) Mounting site
Modules can be used on land except for corrosive salt area and sulfurous area.
Excluded applications include, but are not limited to, installations where modules are
likely to come in contact with any salt water or where likely to become partially or wholly
submerged in fresh or salt water, examples of which include use on boats, docks and
buoys. Don’t install modules in a location where it would be immersed in water or
continually exposed to water from a sprinkler or fountain etc.
Modules are designed for a maximum allowable design pressure of 113 pounds per
square foot, about 5400Pa, which may correspond to a nominal wind speed of
approximately 130 km/h in certain circumstances.
Actual maximum allowable wind speed may be influenced by module type, mounting
configuration, location, and other factors. In no case should modules be exposed to
pressures greater than 113 pounds per square foot of uniformly distributed wind, snow, or
other loading.
Not install modules near naked flame or flammable materials.
When choosing a site, avoid trees, buildings or obstructions. Modules should be mounted
to maximize direct exposure to sunlight and to eliminate or minimize shadowing. Even
partial shadowing can substantially reduce module and system output. Furthermore,
partial shadowing can elevate the shaded portion internal temperature, which may lower
output and shorten module life.
b) Orientation of installations
Modules may be mounted at any angle from a vertical orientation to a horizontal one. The
appropriate fixed tilt angle and azimuth orientation should be used in order to maximize
the exposure to sunlight.
Incorrect orientation of modules installation will result in loss of power output. Modules
connected in series should be installed at same orientation and angle. Different
orientation or angle may cause loss of power output due to difference of amount of
sunlight exposed to the modules.
In the Northern Hemisphere, modules should face south, and in the Southern
Hemisphere, modules should face north.
