6.8 Installation
■
Risk of electric shock: Depending on your model, each module can generate more than 40 V/DC when exposed
to direct sunlight. Contact is potentially hazardous; always use protective equipment.
■
Do not use mirrors or other magnifiers to concentrate sunlight onto the modules.
■
Work only under dry conditions, and use only dry tools. Do not handle panels when they are wet.
■
Risk of electric shock. Do not use a damaged module.
■
Risk of electric shock. Cover the module's surface with an opaque material (e.g., cardboard) during installation
or when working on the module or wiring.
■
Risk of electric shock and/or burns. Do not touch electrically changed parts of the panels (e.g., terminals)
whether then are connected or not.
■
The maximum PV system voltage for that circuit shall be calculated as the sum of the rated open-circuit voltage
of the series-connected PV panels corrected for the lowest expected ambient temperature.
■
Do not connect panels with different orientations or angles of inclination in the same string
■
Do not bend the cable of junction box inappropriately. bending radius of cables should be more than 6 times the
cables' diameter.
■
The rating of the over-current device shall not exceed the maximum series fuse rating of the panel.
■
When several panels are connected together, the total voltage/current of the PV array must be below the max-
imum voltage/current of the inverter, solar charge controller or the maximum system voltage/current of other
connected devices, cables, and connectors.
■
The solar panels need no earth grounding themselves, but earth grounding the balcony guardrail and the solar
PV system should be performed in accordance with all national, state and local electrical codes, regulations and
standards.
■
Do not leave a long extension cable untied after installation.
6.9 Mounting
■
Keep the panels in their original packaging until the moment of their installation.
■
The panel may be handled by the edge, but only if it is held vertically and without exerting excessive or multiple
bending.
■
Check each panel before starting the installation operation. No damaged or broken panels should be used.
■
Do not untie the wires that fixing the cables on the panel.
■
Do not use the junction box or the connection cable as a handle.
■
Do not drop heavy or sharp items onto the panels.
■
Panels should be handled without excess bending (Do not bend panels with a radius of less than 480 mm)
■
To secure panels, use Heavy Duty Zip Ties which are made of corrosion resistant material and for outdoor use.
■
Which side of the panel is on the top is based on the design of the system,
■
Secure the panel to the balcony guardrail with Heavy Duty Zip Ties, through the oval hole on the top of the
panel, then secure the bottom side of the panel with ties.
■
Tied up cables on the rear side of panel against balustrade with nylon zip ties.
6.10 Fire
■
Consult your local authority for fire safety guidelines and structural requirements for building installations.
■
Roof constructions and installations may affect the fire safety of a building; improper installation may create haz-
ards.
