4. Caution before installation
Please read this instruction before installing PV module.
1) The installation of PV module should be performed by qualified personnel only.
2) When installing PV module, you should wear protective equipment.(electric
shock or falling accident risk)
3) When installing PV module, do not step up onto the PV module or place the
object on it.
4) After installation, qualified person shall check whether it operates properly or not.
5) Disassembling or replacing of the PV module part is not allowed without
permission by manufacturer, and if you disassemble or replace anything, please
inform the PV module manufacturer.
6) When disassembling or replacing the part with manufacture’s permission, it
should be performed by qualified person only, and use the certified accessories.
7) For the permission or regulation for installation, please contact the local
authority.
8) When the PV module is damaged or stopped, anyone, even who has useful
knowledge for the PV module, should not approach to the PV module. Touch or
approach may cause serious injury, in which case manufacturer is not
responsible for the damage therefrom.
9) PV module’s orientation shall be at equator direction, and be installed at the
same angle as the latitude of the installation location for the optimal generation
performance. If it is installed at a different angle or direction, it may adversely
affect an annual generation capacity. In case of horizontal installation, S-Energy
recommends regular cleaning to remove dust on the surface.
10) PV module generates the voltage even without load connection. So, be careful
for sparks especially when assembling/disassembling PV module.
11) PV module is intended to be installed on the ground or building.
If you need to install on the vehicle(car, train, etc.) or ship, please request
special modules.
12) Snow, water, dust, or other foreign substance on the surface may increase
reflection of the light and eventually reduce the PV module’s output.(Regular
cleaning of module surface can improve performance).
13) Standard rating specification is measured at the STC AM1.5 condition, and the
performance can significantly improve in the low temperature.
14) Before installation, modules should be stored under packing condition.
15) Irrespective of module connection, contacting current carrying part may cause
a burn or fatal electrical shock from sparks.
16) The shading of the front surface of the module can cause the module
degradation by fire or reduce its lifecycle.
17) When working with the PV module wire, connect the wire with a hanger to
avoid contact on the roof or ground.
18) Potential Induced Degradation [PID] may be caused by ambient high
temperature, humidity, and high system voltage. S-Energy’s PV module
equipped with Enhanced PID module can endure these degradation, but a long
term exposure may also cause PID. To completely prevent PID, trans inverter
and Negative GND should be connected to the (-) GND with the module frame.
5. Caution when installed
1) Please make sure that installed module wire distribution is correct, and
insulation and waterproof performance of connect part is suitably installed.
2) Check if there are any scratches on the frame and front surface of the
glass(The scratch may lead oxidation and reduce the strength)
3) Regularly clean the module with water, and if the module is not cleaned
with water, request to the manufacturer.(*Regular cleaning can
significantly improve the output capacity)
4) The front surface of glass is specially treated, so do not apply any abrasive
cleaning product or chemicals.
5) Periodic inspection should be performed only by qualified personnel with
protective equipment.
6) To avoid shade by the vegetation environment, regular weeding is needed.
