Outdoor field testing has played a vital role in quantifying long-term behavior and lifetime for at least two reasons: it is the typical operating environment for PV systems, and it is the only way
The Performance Loss Rate (PLR) of a research or commercial PV power plant system quan-tifies the decline of the power output over time either as a single assumed linear rate in units of %/a, or %/year, or more recently as a rate over multiple time segments over the lifetime of the system.
High power cutoffs target outliers in the time-series; power values that are unreasonably high. Power presents a unique problem since it is not uniform across systems due to the different technologies installed at different locations that are exposed under different environmental conditions.
Outdoor minimum temperature was found to be the determining factor for long-term stabilized performance. Fanni et al. investigated the annealing and degradation processes in flexible triple junction a-Si modules . The degradation depended on the electric load: it was faster in open-circuit conditions than in short-circuit conditions.
