1.3 Integration in solar system
Design of solar generator
The technical data of the selected solar
generator must be within the solar
inverter‘s specifications (see Technical
Data). Incorrect dimensioning can lead to
reductions in the yield and to destruction
of the unit.
The Sunways design program Sundim
may be helpful to you. Sunways Sundim
is available on the included CD-ROM or
at our homepage www.sunways.de.
Be sure to take the following points into
account before planning your system:
· Watch the celestial alignment of the
modules. A maximum yield is achieved
in Central Europe with a module slope
of 30° to the vertical and direction of
the solar generator field directly to the
south.
· The output of the cells decreases as
the module temperature increases.
Install your solar generator with suf-
ficient ventilation from behind.
· Check your solar generator approx.
every three years for soiling. This oc-
curs especially on the lower edge of
the modules and forms a veil that can-
not be washed off even by heavy rain.
Reduced yield can be prevented by
cleaning with a wet cloth or a brush.
· Avoid switching off individual modules
or solar cells of your system. This can
lead to major decreases in yield.
