Safety Precautions When Installing a Solar
Photovoltaic System
–
Solar modules produce electrical energy when exposed to sunlight.
–
Keep children well away from the system while transporting and installing
mechanical and electrical components.
–
Completely cover all modules with an opaque material during installation to
prevent electricity from being generated.
–
Do not wear metallic rings, watches, or other metallic devices while installing or
troubleshooting photovoltaic systems.
–
Use appropriate safety equipment (insulated tools, insulating gloves, etc.)
approved for use on electrical installations.
–
Observe the instructions and safety precautions for all other components used
in the system, including wiring and cables, connectors, DC-breakers, mounting
hardware, inverters, etc.
–
Use only equipment, connectors, wiring and mounting hardware suitable for use
in a photovoltaic system.
–
Always use the same type of module within a particular photovoltaic system.
–
Under normal operating conditions, PV modules will produce currents and
voltages that are different than those listed in the data sheet. Data sheet values
are applicable at standard test conditions only.
–
Short-circuit current and open-circuit voltages should be multiplied by a factor
of 1.25 when determining component voltage ratings, conductor ampacity, fuse
sizes and size of controls connected to the module or system output.
MECHANICAL INSTALLATION
General Installation Notes
–
Drainage holes must not be covered with parts of the mounting system. The
junction box has a breather port which must be mounted facing downward and
cannot be exposed to the rain. The junction box should be on the higher side of
the module when it is mounted in order to orient the breather port correctly.
–
Do not lift the module by grasping the module's junction box or electrical leads.
–
Do not stand or step on the module.
–
Do not drop the module or allow objects to fall on the module.
–
Do not place any heavy objects on the module.
–
Inappropriate transport and installation may damage the module's glass or frame.
