7.1 General Installation Rules
The PV system installation requires professional knowledge and technique, and should be
installed by qualified persons with specialized and licensed installation tools.The module
installers undertake all the risk of injury including electric shock. The module installation should
abide by all the local applicable laws and regulations, including local,regional and host countries.
The construction electric installation permit should be obtained in necessity.
PV module converts light energy to direct current energy, which is specially design for
outdoor use. The modules can be installed on the ground, bracing piece or the roof. The
designer and installer of the system are responsible to design the support structure correctly.
The installation can only be operated under dry conditions with dry tools. Do not handle wet
modules, unless the carrier is wearing proper protective equipment. Please stop the installation
when it is snowy, rainy or windy.
Do not wear any metal object such as watch, ring, earring, nose ring or oral ring,etc. Please
do not touch the module with bare hands which will lead to dangers like scald or electric shock
because the surface and the frame of the glass may be very hot.
Due to the thermal expansion and contraction effect of the module frame, the distance
between two adjacent modules should be bigger than 10mm.
The
end of the junction box
should be installed in a relatively high place when installing.
The screw should be installed with the set mounting holes on the module frame. The most
common screw installation is with the four symmetrical mounting holes in the middle of the
module frame. Eight mounting holes are required to be all installed when the system is installed
somewhere with frequent wind and snow.

A. To obtain the maximum generation efficiency, the module should be installed southward
when in the Northern Hemisphere, and northward when in the Southern Hemisphere.
B. The module can be installed lengthways or sideways. Do check whether the length of the
