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