Diene Monomer) rubber or similar material is recommended). The base shall be fixed, not
mobile. Avoid any direct contact between the module and any metallic part or component
on the base.
j)
Avoid unnecessary touch on the module during installation. The module surface may be
highly hot, which may cause burns or electric shock.
5.2 Selection of installation conditions
5.2.1 Working conditions
The recommended ambient environment for module installation is -40°C to 85°C (-4°F to
185°F).
Ensure that there is sufficient clearance between modules to keep ventilated, especially at high
temperatures.
Ensure that the wind or snow pressure on the module, after installation, does not exceed the
maximal allowed load.
If a module is under a salt mist (i.e. marine environment) or sulfur-bearing (i.e. sulfur-bearing
source or volcano) environment, it may suffer corrosion.
No module shall be soaked in water (pure water or salt water), or touch water for long time
(e.g. fountain or spray).
5.2.2 Geographical conditions
Solar modules shall be installed at locations where modules receive most illumination
throughout the year. In the northern hemisphere, a module should preferably face the south, while in
the southern hemisphere, a module should preferably face the north. When choosing a location,
avoid any tree, building or other obstacle that may cast any shadow on the module. Although the
manufacturer has installed appropriate bypass diodes to minimize such losses, a shadow may still
reduce the output power.
Do not install any module near open fire or inflammable materials.
Do not install any module at any location that may be soaked in water or continuously exposed
to any water truck of fountain.
5.2.3 Selection of angle of inclination
The angle of inclination of a solar module means the included angle between the module surface
and the ground level (as in Fig. 1); the module has the biggest power output when it vertically faces
the sun.
