A new study analyzing long-term performance data from more than one million photovoltaic installations in Germany indicates these systems are aging more slowly than many industry assumptions had suggested. According to research published in Energy Economics and reported by pv magazine, the analysis of 16 years of operational data reveals an average annual degradation rate between 0.52% and 0.61%.
The scale of the research, which tracked 1.25 million systems, allowed for a detailed assessment of factors influencing performance over time. Environmental conditions were found to significantly affect output, with extreme heat, frost, and air pollution having measurable impacts. The study noted that decreasing air pollution in Germany has contributed to higher energy yields in recent years, an effect distinguishable from climate variability and aging.
Findings also indicated that system size correlates with degradation rates, with larger installations tending to lose efficiency faster than smaller ones. This suggests utility-scale solar projects require distinct reliability and maintenance strategies compared to residential rooftop systems. The slower degradation rate improves long-term project economics, reducing the levelized cost of electricity compared to calculations based on earlier assumptions.
The research methodology involved calculating performance ratios according to international standards, using production data from transmission system operators and detailed solar irradiance information. Regression analysis isolated the average annual efficiency loss while accounting for variables including hot days, frost days, and pollution. The study concluded that the results support the long-term reliability and financial viability of photovoltaic technology.
