We have finished the first three measurement days. In general the weather is fine, however the 23rd clouds made us stop working at the end of the day. Below the data of May 24th, all broadband sensors mounted on our trackers.

qualitative analysis of solar spectra measured on 22th May 2016 in Trisaia (Italy). Match ratio (broadband measured irradiance vs broadband irradiance of reference spectrum ASTM AM1.5) in different wavelength ranges. The match ratio decreases in the range 400-600 nm and increases in the range 600-1100 nm as long as the solar spectrum gradually shiftes to higher wavelengths (red content)
