Yingli Solar offers the YGE-Z Series PV module which features a
modified aluminum frame that is compatible with mounting and
grounding hardware manufactured by Zep Solar. Refer to the
‘YGE-Z Series Installation Supplement’ for installation information.
Detailed design and installation information of Zep Solar’s mounting
systems can be found at
http://www.zepsolar.com/resources.html
.
The YGE-Z Series PV module warranty will become void if
non-Zep-certified hardware is attached inside the Zep Groove of
the module frame.
YGE-Z Series PV modules are also compatible with the mounting
and grounding methods included in this manual.
M A I N T E N A N C E
Yingli Solar recommends that PV systems be periodically inspected by
the installer, or other qualified person.
The purpose of the PV system inspection is to ensure that all system
components are functioning properly. At a minimum, this inspection
should confirm the following:
– All cables and connector attachments are undamaged
and properly secured
– No sharp objects are in contact with the PV module surfaces
– PV modules are not shaded by unwanted obstacles
and/or foreign material
– Mounting and grounding components are tightly secured
with no corrosion
Defects should be addressed immediately.
Cleaning
Over time, dirt and dust can accumulate on the glass surface of the
module, reducing its power output. Yingli Solar recommends periodic
cleaning of PV modules to ensure maximum power output, especially in
regions with low precipitation.
In order to reduce the potential for electrical and thermal shock, Yingli
Solar recommends cleaning PV modules during early morning or late
afternoon hours when solar radiation is low and the modules are cooler,
especially in regions with hotter temperatures.
Never attempt to clean a PV module with broken glass or other signs of
exposed wiring, as this presents a shock hazard.
Clean the glass surface of the PV modules with a soft brush using soft,
clean water with a recommended pressure less than 100psi (690kPa),
which is typical of most municipal water systems. Water with high
mineral content may leave deposits on the glass surface and is not
recommended.
Yingli Solar PV modules may contain a hydrophobic anti-reflective
coating on the glass surface to enhance power output and reduce dirt
and dust buildup. In order to avoid module damage, do not clean PV
modules with a power washer or pressure washer. Do not use steam or
corrosive chemicals to facilitate the cleaning of modules. Do not use
aggressive tools or abrasive materials that could scratch or damage the
glass surface. Failure to comply with these requirements may adversely
affect the PV module performance.
Yingli Solar PV modules are designed to withstand high snow loads.
However, if removing snow is desired to enhance production, use a brush
to gently remove snow. Do not try to remove frozen snow or ice from PV
modules.

The dismantling of PV systems must be performed with the same
care and safety precautions used during the initial installation. The PV
system can generate hazardous voltage even after the system has been
disconnected. Follow safety regulations for working with live electrical
equipment.
