These 2 IV curves are from an external solar module testing facility. 2 full sized modules are featured, a standard poly silicon Aluminum Back-Surface Field (AL-BSF) module and a similar sized Passivated Emitter Rear Contact (PERC) mono silicon module. The PERC module has a clearly higher power per output per area compared to the Al-BSF module given the higher voltage and current output with a similar fill factor.
library(ddiv) data("IV_5M_1") IVExtractResult(IV_5M_1) data("IV_5M_2") IVExtractResult(IV_5M_2)
The result for finding steps for example data "IV_5M_1" and "IV_5M_2", no changepoint identifying step is found.
