Production performance


General SOLAR PV uses flexible photovoltaic cells made with thin-film triple-junction amorphous silicon.
This is therefore a consolidated technology that offers better yield in terms of electricity compared to traditional systems with rigid panels. Indeed, a number of comparative studies conducted by independent third parties and universities show that amorphous silicon has a higher overall yield per kWp installed (see chart), even when amorphous silicon is installed in unfavourable conditions (for instance North-East).There are two basic technical reasons that explain the higher production of kWh:

• amorphous silicon makes full use of summer months. As the operating temperature rises it retains its performance better compared to rigid systems, even if in most cases these have a ventilation at the rear due to the type of assembly (inclined southwards);

• amorphous silicon produces energy even with limited solar irradiation, reflected radiation and diffused light (predominant on cloudy days, in the morning and the evening and can account for 35% of overall incident radiation).

The blue, green and red components of the solar spectrum - which constantly changes during the day - are absorbed in different layers of the thin film, which also operates when covered by shade. It is not necessary to turn the General SOLAR PV photovoltaic cells SOUTHWARDS and tilt them. The thin film works perfectly also on flat surfaces (the orientation of the modules has a limited, basically irrelevant influence).It is possible to install General SOLAR PV systems that are 100% efficient also on roofs without optimal orientation.
The thin film works in any case and therefore it is possible to also make use of shaded areas with unfavourable positioning, which other systems do not take into account.
