A Solar I-V Curve Tracer is a device that is vital in testing the real-time performance of solar PV modules and strings. It aids in gauging of current voltage properties, fault detection and power output at real operating conditions. A Solar I-V Curve Tracer is widely used in commissioning, maintenance, and diagnostics of the solar panels to test the performance of the PV systems and analyze the efficiency of the solar panels and the configuration of the systems and troubleshoot them to achieve maximum energy output and reliability.
