ANNEX D: COASTAL AREA ANTI-CORROSION INSTALLATION GUIDELINES
D.1.0: GENERAL INFORMATION
According to the specific conditions stipulated in the
Canadian Solar installation manual and general
warranty statement, Canadian Solar PV modules are
not allowed to be installed in coastal areas. Coastal
areas are defined as places located within 100m of the
defined coastline.
This annex has been created to facilitate approval for
customer PV installations located within 20 m and 100
m of the coastline. It lays down general requirements
to ensure that Canadian Solar PV modules are installed
properly and reliably in coastal areas, which include but
are not limited to relevant anti-corrosion principles for
both the modules and associated mounting systems.
This annex summarizes the key technical requirements
stipulated by well-known international standards and
explains how they apply to photovoltaic systems.
Please read this annex carefully and strictly follow any
relevant instructions prior to installing Canadian Solar
modules in coastal areas. Failure to follow these
instructions and other general anti-corrosion principles
may result in corrosion damage to the photovoltaic
modules and/or their racking systems, and will void the
Canadian Solar standard product and performance
warranty. For further inquiries, please contact our
customer service department or our local
representatives for more information.
The reliability of photovoltaic modules strongly
depends on their distance from the coastline. Different
coastal land areas are defined according to how far
away from the coastline they are; Canadian Solar
generally classifies seashore PV installations according
to four different groups:
Distance from the coastline
(X: meters)
Requirements
X ≤ 20m
Installation strictly prohibited by Canadian Solar due to concerns of salt-mist
corrosion.
20m < X ≤ 100m
Installations must comprise of Canadian Solar ‟special-anti-corrosion” modules.
These installations must comply with the instructions listed below section
D.2.1/D.2.2/D.2.3/ D3.0.
100m < X ≤ 500m
We recommend installing Canadian Solar ‟special-anti-corrosion” modules.
We recommend following the instructions listed under sections
D.2.1/D.2.2/D.2.3/D.3.0
X > 500m
Follow section 7.0
Local conditions strongly influence the salt deposition
rate, which is particularly, but not exclusively,
dependent on specific regions and local wind patterns.
Canadian Solar reserves the right to adapt the above
definition to individual cases. Please contact your local
representative to confirm which category your PV
system falls under.
The word “coastline” in this manual refers to the area
where the land meets the sea during high tide.
In this manual, “distance to the coastline” refers to the
shortest distance between the photovoltaic module
array and the coastline.
Please consult the Canadian Solar technical support
department or your local representative for more
information on installing ‟special anti-corrosion”
modules.
