Yingli Solar PV Modules, Installation and User Manual

• Bolts: Modules must be mounted using the mounting holes located on
the rear side of the long frame parts using ¼ inch stainless steel bolts,
nuts, and washers. Refer to the racking manufacturer for specific torque
requirements. This mounting method has been tested for a maximum
static load of 50 psf (2400 Pa) in both the positive and negative directions.

• Top-down Clamps: Third-party clamps that have been designed for PV
mounting structures are an approved mounting attachment method for Yingli
Solar PV modules. Modules must be fastened using clamps applied to the top
side of the long frame parts. A clamp holds two modules except for the clamps
at the beginning and end of a module row. The centerline of the clamps must
be in line with the mounting hole positions plus or minus a distance of two
(2) inches (50mm). Clamps must be installed according to the manufacturer’s
specified instructions with minimum bolt size of 1/4 inches. Do not apply
excessive pressure on the frame such that the frame deforms. Refer to the
clamp manufacturer for specific hardware and torque requirements. This
mounting method has been tested for a maximum static load of 50 psf (2400
Pa) in both the positive and negative directions.

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 please find “ YGE-Z Series Installation Supplement”.
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.

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.
