Abstract

The performance degradation, or the energy output loss over time, of solar panel array is a major concern to solar energy stakeholders. A wide variety of degradation rates has been reported in the literature with respect to technologies, ages, manufacturers, and geographic locations. With such a variety of factors involved, it is very difficult, if not impossible, to find a parametric model to detect abrupt performance change. We present a nonparametric detection method to retrospectively identify the time points of abrupt changes, and demonstrate its superiority over other detection methods using simulated and real data. The proposed method will help solar energy stakeholders in several aspects including warranty underwriting, preventive maintenance planning, and financial analysis.
