Integration of the <strong>solar</strong> inverter into the<br />
PV system<br />
Design of the PV generator<br />
The technical data of the selected PV<br />
generator must be within the specification<br />
of the <strong>solar</strong> inverter (see Technical Data).<br />
Incorrect dimensioning can cause losses in<br />
yield and destruction of the unit. The<br />
<strong>Sunways</strong> NT Sundim design program for<br />
the PV generator may be helpful. <strong>Sunways</strong><br />
NT Sundim is available on the enclosed<br />
CD or from our website, www.sunways.de.<br />
· Check your PV generator for soiling ca.<br />
every three years. This occurs particularly<br />
at the lower edge of the modules and<br />
forms a film, which even heavy rain cannot<br />
wash away. Decreases in yield can be<br />
prevented by cleaning with a wet cloth<br />
or a brush.<br />
· Avoid shading of individual modules or<br />
<strong>solar</strong> cells in your system. This can result<br />
in heavy losses in yield.<br />
Please take account of the following points<br />
before planning your system:<br />
· Pay attention to the skyward alignment<br />
of the modules. You will obtain maximum<br />
yield in Central Europe with a<br />
module inclination of 30° to the horizontal<br />
and a direct southerly alignment<br />
of the generator field.<br />
· The output of the cells decreases as the<br />
module temperature increases. Install<br />
your PV generator with adequate rear<br />
ventilation.<br />
