General
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 (PH6-9) with a recommended pressure less than 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.
D E CO M M I S S I O N I N G
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.

Yingli Solar is a member of PV Cycle, the European association for voluntary
take back and recycling of PV modules. Please contact PV Cycle at www.
pvcycle.org for details regarding the recycling process.
Meaning of crossed –out wheeled dustbin:
Do not dispose of electrical appliances as unsorted municipal waste, use
separate collection facilities.
Contact your local government for information regarding the collection systems
available.
If electrical appliances are disposed of in landfills or dumps, hazardous
substances can leak into the groundwater and get into the food chain, damaging
your health and well-being.
When replacing old appliances with new ones, the retailer is legally obligated to
take back your old appliance for disposals at least free of charge.
