Site Selection; Tilt Angle Selection - JinkoSolar JKM350PP-72-DV Installation Manual

based on the approved mounting methods. The professional system installer must be
responsible for mechanical load calculation according to the system design.

2.2.2 Site selection

In most applications, Jinko solar 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 open 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 an insulated and ventilated battery case specifically designed for the
purpose.
Do not install the PV module in a location where it would be immersed in water or
continually exposed to water from a sprinkler or fountain etc.

2.2.3 Tilt angle selection

The tilt angle of the PV module is measured between the surface of the PV module
and a horizontal ground surface (Figure 1). The PV module generates maximum
output power when it faces the sun directly.
