·
The minimum distance between a module frame and a sidewall of clamp for linear thermal expansion
of the module frame supports should be 2.5mm, in order to reduce pressure loads.
·
All the junctions on the conductive connection must be fixed. Metal containing iron in the conductive
connection should be made with stainless steel or be treated against corrosion by anodizing, spray-
painting, or galvanization to prevent rusting and corrosion.
·
Modules that feature antireflective coated glass are prone to visible finger print marks if touched on
the front glass surface. HHI recommends handing modules with anti-reflective glass with gloves or
limiting touching of the front surface. Any finger print marks resulting from installation will naturally
disappear over time or can be reduced by following the washing guidelines in Section 7.1.
3.3 General Operation Condition
PV modules will be operated under General Operation Condition (GOC). Do not install PV module at
site beyond General Operation Conditions or under specific condition.
1) General Operation Conditions
The site condition for the sea level and wind load should be matched the following requirements.
(1) Sea level of site : Below 1,000m (3,280ft)
(2) Maximum Instantaneous wind Speed
·
Below 5,400Pa (5,400N/m
2
, 550kg/m
2
,
112lb/ft
2
) on the front module surface
·
Below 2,400Pa (2,400N/m
2
, 225kg/m
2
,
46lb/ft
2
) on the back module surface
※
If the wind strength is not over than 2,400Pa (2,400N/m
2
, 225kg/m
2
,
4 lb/ft
2
), the installation site
over 1,000m (3,280ft) above sea level is permitted.
※
Installations under the condition of wind strength specified above are allowed only when the
methods of installations comply with Module Installation Instruction (Appendix 1.)
2) Specific Site Condition
(1) Actual site condition should be checked for adequate installations.
1) Chloride is an important factor to be considered.
2) Hail, heavy snow, and sand are important factors to be considered.
3) Air pollution, chemical gas, acid rain, and smoke are important factors to be considered.
(2) Environmental conditions.
1) PV modules shall not be installed in salty area within 500m from a body of salt water and/or area
where salty wind hit directly.
※
HYUNDAI modules have passed the IEC61701 test (Salt Mist Corrosion Test)
2) PV modules shall not be immersed in water and shall not be continually exposure to Water from a
sprinkler, fountain, etc.
3) PV modules shall not be installed in sulfurous area near sulfurous volcano and sulfurous spring.
