Before installing your solar system, contact local authorities to determine the necessary permit,
installation and inspection requirements that must be followed. System should be installed by
qualified personnel only. The system involves electricity, and can be dangerous if the personnel
are not familiar with the appropriate safety procedures. PV modules should be mounted in a
location where they will receive maximum sunlight throughout the year. Specially, in the northern
hemisphere, the modules should face south. And in the southern hemisphere, the modules should
face north.
SYSTEM
DESIGN
•
In order to achieve maximum annual yield, optimum orientation and tilt of PV module is necessary.
Sunlight shining vertically and completely onto PV module is the best condition to generate
maximum power.
•
Artificially concentrated sunlight shall not be directed on the module. Very hot module(s) can
reduce power output performance. Ensure the module has good ventilation conditions to prevent
overheating.
•
Site-specific environment loads such as wind and snow should be taken into account to avoid
exceeding the maximum load.
•
When designing the system, please pay attention to the total voltage (if connected in series) and
current (if connected in parallel).
•
You must not install more than three (3) modules in parallel without additional string fuses or string
diodes. While in series, the open circuit voltage of the string must not exceed the allowed maximum
system voltage (e.g. 1000Vdc for IEC certified systems), even under cold climate conditions.
•
The module must not be installed close to fire or flammable materials. Completely cover the module
with an opaque material during installation to prevent electricity from being generated.
•
Supplementary: If system grounding is required by system configuration or local authorities,
Hanwha SolarOne recommends negative system grounding which could have
positive effect on system performance.
