4.2. Tilt angel selection
The tilt angle of the modules is measured between the surface of the modules and a horizontal ground surface. The
modules generate maximum power output when it faces the sun directly.
In the northern hemisphere, modules should typically face south, and in the southern hemisphere, modules should
typically face north.
For detailed information regarding the best installation angle, please refer to standard solar photovoltaic installation
guides or consult a reputable solar installer or systems integrator.
Dust building up on the surface of the modules can impair module performance. Hyperion Solar recommends installing
the modules with a tilt angle of at least 10 degrees, making it easier for dust to be washed off by rain.
5. MECHANICAL INSTALLATION
5.1. Conventional requirements
Ensure the installation method and supporting system of modules is strong enough to withstand all the load conditions.
The Installer must provide this guarantee. The installation supporting system must be tested by third-party organization
with the analysis ability of Static Mechanical, according to the local national or international standards.
The modules mounting structure must be made of durable, corrosion- resistant and UV- resistant material.
Modules must be securely attached to the mounting structure.
In regions with heavy snowfall in winter, select the height of the mounting system so that the lowest edge of the modules
is not covered by snow for any length of time. In addition, ensure that the lowest portion of the modules is placed high
enough so that it is not shaded by plants or trees or damaged by flying sand.
When the modules are supported parallel to the surface of a building wall or roof, a minimum clearance of 10cm
between the modules frame and the surface of the wall or the roof is required to allow air to circulate behind the
modules and to prevent wiring damage.
Do not attempt to drill holes in the glass surface and the frames of the modules as this will void the warranty.
Before installing modules on a roof, ensure that the roof construction is suitable. In addition, any roof penetration
required to mount the modules must be properly sealed to prevent leaks.
Observe the linear thermal expansion of the module frames (the recommended minimum distance between two
modules is 10 mm). The module frames will warp at low temperature.
Avoid the frame receiving the lateral tension and pressure, which may damage the frame and glass.
Modules have been certified for a maximum static load on the back side of 2400Pa (i.e., wind load) and a maximum
static load on the front side of either 2400 Pa or 5400Pa (i.e., wind and snow load), depending on the modules type
(please refer to the following installation methods for details).
The mounting method must not result in the direct contact of dissimilar metals with the aluminum frame of the modules
as it will result in galvanic corrosion. IEC 60950-1 standard recommends metal combinations not exceed an
electrochemical potential difference of 0.6 Volts.
Hyperion Solar modules can be mounted in landscape or portrait orientation. For the bifacial modules, in order to
maintain the energy yield of module’s rear side, the distance between the bottom of modules and the
