Abstract/Summary:


We present recent data relevant to both 55 Arco-Solar modules of the array in field exposure since 1980 in a devoted area at the ENEA Casaccia research center and 26 module-strings of the 100 kW-plant installed in 1990 at the ENEA-Casaccia parking. Analyzing the new data together with data gathered in previous measurement campaigns allows detecting that, in both the array and plant, the amount of failed modules is likely to increase exponentially with time and efficiency degrades non-linearly with time.
