C.3.0: ANTI-CORROSION SUGGESTIONS FOR THE
RACKING SYSTEM
Suggestions for the racking system are provided below.
The warranty does not cover the damage to the mounting
system caused by corrosion if the mounting system is not
provided by Canadian Solar. The requirements below apply
to two main mounting systems: aluminum alloy-based
racking for rooftops and galvanized steel-based structures
for ground-mounted solar farms. To prevent salt-mist
corrosion, Canadian Solar requires strict compliance with
the following principles:
Use approved corrosion-resistant materials (e.g. stainless
steel SUS 316 or carbon steel with a hot-dip galvanized
coating) for any racking or BOS components used in
coastal areas.
Process specifications for the different components must
comply with relevant international anti-corrosion standards.
Minimum coating thicknesses for hot-dip galvanized and
anodizing oxide components must comply with the
standard minimum requirements stipulated in JIS8641 and
JIS8601.

Use mounting components that contain the same metals or
metals with a similar electrochemical potential. The metal’s
coating should also be taken into account. There may be a
big difference between the electrochemical potentials of
two different coating materials.
C.4.0: Precautions and General Safety
Before installing any modules, contact the
appropriate authorities to obtain any relevant
approvals and learn of any site, installation and inspection
requirements.
When applying coating materials, workers must follow
applicable health and safety legislation and apply all
respective preventive and proactive measures described
within.
C.5.0: LIMITATION OF LIABILITY
Canadian Solar shall not be held responsible for damages
