Table 3

Incident irradiance and energy flux at the aperture and on the surface of a PV cell for the CPC and V-trough collector for the two experimental test conditions.

Type of the experiment	System description	Intensity on the aperture (±20 W/m^2)	Energy on the aperture (W)	Intensity on the PV cell (±20 W/m^2)	Energy at the PV cell (W)
