3. Installation Environment
3.1 General
·Before installing and operating HES PV system, installer and operator should follow the requirements
specified in this manual.
·Do not drill additional holes in the frame of the modules. This additional hole will void the warranty.
Refer to the mounting profile in Picture 1.
·Secure the module using mounting holes provided and stainless corrosion resistant material. Locking
washers should be used for long-term security.
·Appropriate materials should be used for mounting structure in order to prevent the module frame,
mounting structure from corrosion.
·When installing the system, it is necessary to avoid any shade caused by buildings or trees nearby.
·For more information about the installation, please contact HES or local representatives for more
detailed information.
3.2 Notes on Installation
·Space between PV module frames and installation objects is necessary for cooling air circulation. Do
not seal this space. Minimum 4 inch (10.14 cm) of standoff height is necessary.
·The minimum distance between two fixed modules for linear thermal expansion of the module frame
supports should be 10 mm. Nevertheless, the recommended distance between two modules is 30
mm to allow wind circulation, in order to reduce pressure loads and improve module ventilation.
·The minimum distance between a module frame and a sidewall of clamp for linear thermal expansion
of the module frame supports should be 1.5 mm, 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. HES recommends handing modules 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 6.2.
·Do not install PV modules horizontally. Horizontal installation can cause performance drop of PV
modules. HES recommends mounting modules at a 12.5°tilt or greater.
3.3 Installation Site
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 Site Conditions
The site condition for the sea level and wind load should be matched the following requirements.
(1)Sea level of site : Below 1,000 m (3,280 ft)
(2)Maximum Instantaneous wind Speed (design load, safety factor = 1.5)
·Below 2,400Pa or 3,600Pa on the front module surface
