2.2 Installation Condition
2.2.1 Climate condition
Please install the modules in the following conditions:
a)Operating temperature: within –40°C(-4°F) to 85°C (185°F)
b)Relative humidity: within 10% to 95%.
c) Do not install modules above 2000m altitude above sea level.
﹡Note: The mechanical load bearing (include wind and snow loads) of the module is
based on the mounting methods. The professional system installer must be responsible
for mechanical load calculation according to the system.
2.2.2 Site selection
In most applications, SunSpark Technology Inc PV modules should be installed in a
location where they will receive maximum sunlight throughout the year. In the Northern
Hemisphere,
the module should typically face south, and in the Southern Hemisphere, the
modules should typically face north. Modules facing 30 degrees away from true South
(or North) will lose approximately 10 to 15 percent of their power output. If the module
faces 60 degrees away from true South (or North), the power loss will be 20 to 30
percent.
When choosing a site, avoid trees, buildings or obstructions, which could cast
shadows on the solar photovoltaic 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 PV module will minimize any such loss.
Do not install
the PV module near naked flame or flammable materials.
When solar modules are used to charge batteries, the battery must be installed in a
manner, which will protect the performance of the system and the safety of its users.
Follow the battery manufacturer’s guidelines concerning installation, operation and
maintenance recommendations. In general, the battery (or battery bank) should be away
from the main flow of people and animal traffic. Select a battery site that is protected
from sunlight, rain, snow, debris, and is well ventilated. Most batteries generate
hydrogen gas when charging, which can be explosive. Do not light matches or create
sparks near the battery bank. When a battery is installed outdoors, it should be placed in
