Introduction
This example application demonstrates how to use the Model 2461 Interactive SourceMeter
®
Instrument to measure the I-V characteristics of a solar panel.
From the I-V characteristics measured by the Model 2461, you can determine important parameters
about the solar panel, including:
 Maximum current (I
max
) and voltage (V
max
)
 Maximum power (P
max
)
 Open circuit voltage (V
oc
)
 Short-circuit current (I
sc
)
Because the Model 2461 has four-quadrant source capability, it can sink up to 7 A of cell current as a
function of the applied voltage.
Equipment required
 One Model 2461 Interactive SourceMeter
®
Instrument
 For front-panel connections, use four insulated banana cables, such as the Keithley Instruments
Model 8608 High-Performance Clip Lead Set (one set included with the Model 2461; you will
need another set)
 For rear-panel connections, use one Model 2460-KIT Screw-Terminal Connector Kit (provided
with the Model 2461), or you can use one set of Model 2460-BAN Banana Test Leads/Adapter
Cables (with appropriate connections to the device)
 One solar panel
