Estimating the Degradation Rate of Photovoltaic Arrays Using a Two-Component Nonlinear Model
Chris Gotwalt, Director of JMP Statistical R&D, demonstrates how to use JMP® or JMP® Pro to model the degradation of solar cell data.
Based on only one year of data, he predicts the relative power output of solar cells for five years into the future. This has implications for predicting when new cells need to be serviced and taken offline. Gotwalt uses data supplied by a solar group. To maintain confidentiality, he scaled the data to provide relative rather than absolute power output. One could also apply the same model and techniques to un-scaled data.
