Abstract

The REAPER project to develop an i-v curve tracer seeks to develop a flexible and scalable, low-cost test bed for obtaining current-voltage measurements of photovoltaic (solar) modules. Capable of characterizing from a cell to an array, and from one to many samples, the system is based on a Keithley SourceMeter to perform the measurement, a plurality of relay boards to perform the interconnections between the SMU and the device under test, and a Raspbery Pi to control the entire process.
