Daystar DS-100C

The Daystar DS-100C I-V curve tracer is a 12 kg portable, self-contained instrument designed for photovoltaic system testing. Packaged in a durable non-metallic case, it features dual capacitance settings: approximately 1,500 μF at 600V high range and 5,000 μF at the low voltage setting. Using a capacitive load, the DS-100C adjusts impedance at PV array outputs, ensuring precise measurement of voltage, current, and derived parameters. The device uniquely supports slower sweep rates through load capacitor switching, yielding highly accurate I-V curves for both single cells and series-parallel arrays.

Measurements captured include Voc, Isc, Peak Power, Vpk, Ipk, and Fill Factor, with data transferred to a control computer via IVPC Windows software for detailed analysis, display, and storage. This ensures reliable, repeatable photovoltaic performance evaluations across diverse applications.
