SUPSI researchers found that six Swiss photovoltaic systems installed in the late 1980s and early 1990s show exceptionally low degradation rates, ranging from only 0.16 to 0.24% per year, after more than 30 years of operation. The study shows that thermal stress, ventilation and material design have a greater impact on the long-term reliability of modules than altitude or irradiation alone.
