Specific Annual Yield<br />

The specific annual yield is an evaluation dimension that gives the system’s annual yield<br />

standardised to the installed output. In other words, the specific annual yield corresponds<br />

to the system’s peak load operating hours.<br />

Another well known evaluation dimension is calculated from the specific annual yield: the<br />

final yield. The final yield is the specific annual yield divided by 365 days.<br />

System Efficiency<br />

The system efficiency is the quotient from the usable solar energy from the PV system and<br />

the total energy irradiated onto the generator surface. It is made up of the PV array<br />

efficiency, the inverter efficiency and the cabling losses.<br />

Wind Speed at a Height of 10m<br />

The wind speed is accounted for when defining the module temperature in the dynamic<br />

Temperature model. In the climate data files provided the wind speed is measured at a<br />

height of 10 metres.<br />
