During
the installation and construction of PV power
station or household system, consideration should
first be given to the following factors:
1£®PV power system shall be designed
in such a way that its highly reliable performance
and normal operation under severe conditions can
be guaranteed. Meanwhile, the system is required
to be easy for operation and maintenance, thus
convenient for users¡¯ operation and daily maintenance.
2£®Considering
the low-cost design, manufacturing and construction
of the complete set of PV power system, standardized
and modularized design of the equipment and enhancement
of the versatility and interchangeability of spare
parts, it is required that the system shall reserve
expansion interface for the future increase of
scale and capacity.
3£®During concrete implementation,
the solar module shall be installed with appropriate
azimuth angle and inclination angel, so as to
ensure that the solar module achieves most optimized
performance. Selection of the installation place
shall guarantee that the module can be irradiated
by sunlight from 9:00 AM to 3:00 PM during days
with minimum exposure time throughout the year
in the local area.
4£®Installation structure of the module
shall be able to resist environmental stress of
wind, snow, etc. and the mounting holes shall
guarantee easy installation and protection from
mechanical stress. It is recommended to use correct
materials for installation structure so that corrosion
of the module frame, installation structure and
materials could be reduced to the minimum.
