An apparatus for measuring electrical characteristics of solar panels (photovoltaic modules) wherein the apparatus measures current versus voltage ('I-V') relationships for both illuminated ('light I-V') and/or non-illuminated (&#x201c;dark I-V&#x201d;) conditions; optionally provides single, dual, or four-quadrant source/sink capability; and measures one or more devices under test (DUTs). The apparatus comprises one or more source measurement units (SMUs), wherein each SMU is connected to one DUT, and optionally includes a positive high-voltage programmable power supply and/or a negative high-voltage programmable power supply. Additionally, the apparatus includes a controller which controls the functions of the SMUs, the high-voltage supplies, and other components of the apparatus, wherein the controller communicates with the SMUs over a signal bus. Finally, the apparatus may include a computer to provide a user interface, communicate with the controller to initiate measurements and record results, analyze resulting data to determine measured parameters, and/or store the measured data.
