Solar Panel I-V Measurement System
SS9600

I-V measurement system for high-capacity solar panels up to 320 W

The SS9600 has six output ranges for solar panel evaluation: maximum 320 W (20 V/16 A, 40 V/8 A, 80 V/4 A) and maximum 280 W (7 V/40 A, 14 V/20 A, 28 V/10 A), that cover the I-V characteristics of most solar cells and panels.
By using DC voltage/current sources, not only I-V characteristic but also dark current characteristic evaluation in irradiation is available. The SS9600 can measure finely around Isc and Voc with the minimum step of 4ms by using the random sweep function in addition to the linear sweep function. That is, it can measure all types of solar cells including crystal, film and tandem solar cells.
