I-V Curves from External Solar Testing Laboratory
In ddiv: Data Driven I-v Feature Extraction

Data Description

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.

Load data and run code to extract IV features

library(ddiv)
data("IV_5M_1")
IVExtractResult(IV_5M_1)

data("IV_5M_2")
IVExtractResult(IV_5M_2)

Example output

The result for finding steps for example data "IV_5M_1" and "IV_5M_2", no changepoint identifying step is found.
