• Modules can be installed in both landscape and portrait modes
• The PV modules shall be installed high enough to keep it away from potential
shading, windblown sand, snow and water.
• It is recommended that installation of the PV modules be 30cm away from the
ground to insure adequate ventilation.
• Appropriate installation structure shall be chosen to meet required mechanical
load.
• It is recommended that PV modules be installed with a minimum tilt angle of 10
degrees to facilitate cleaning and washdown.
• It is recommended to maintain minimum 10mm gap between PV modules for ther
mal expansion of materials.
• Install PV modules appropriately according to corresponding mechanical load
needs.
It is recommended that PV modules be installed where there is excellent solar inso-
lation. In the Northern Hemisphere, the module should typically face south, and in
the Southern Hemisphere, the modules should typically face north. The most opti-
mum installation angle varies according to different latitudes and longitudes; please
consult experts with appropriate knowledge background when determining the
installation locations and angles.
Each PV module has 8 mounting holes(shown on drawing1-1).The downward
mechanical load resistance of module will be different based on the location of
the installation holes used(shown as table 1-1).The module frame must be
attached to a mounting rail using M8 corrosion-proof screws together with
spring washers and flat washers in eight symmetrical locations on the PV
module. The applied torque should be adequate to attach it firmly. The refer
ence torque value for M8 screws is 16~20N*m.
When choosing a site, avoid trees, buildings or obstructions which could cast shad-
-ws on the solar photovoltaic modules. Shading can cause hot spots and loss of out-
-put. Factory fitted bypass diodes will minimize such effect.
Do not install the PV modules near naked flame or flammable materials.
Do not install the PV modules in a location where it would be immersed in
water or constantly exposed to water from a sprinkler or fountain etc.
