Abstract — Solar Panel Current Voltage Iv Curve Tracer Arduino
Single-Ended Primary Inductor Converter (SEPIC) to replace bulky conventional resistive or capacitive loads. By dynamically adjusting the duty cycle of the SEPIC converter, the system varies the equivalent input resistance seen by the PV module. This enables a smooth, automated sweep from near short-circuit current to near open-circuit voltage, capturing comprehensive performance data for 1.5 W and 15 W solar panels.
Operational Methodology & Framework
Figure 1: Conceptual Model & Experimental Workflow for Solar Panel Current Voltage Iv Curve Tracer Arduino 2. System Architecture & Functional Block Diagram The core analysis relies on the SEPIC converter's ability to present a variable equivalent resistance, $R_{pv}$ , to the PV module. The relationship between the converter's duty cycle ( $D$ ), the output load resistance ( $R_o$ ), and the PV-side resistance is defined as: $R_{pv} = \left(\frac{1-D}{D}\right)^2 R_o$ . Sweeping the duty cycle changes $R_{pv}$ , shifting the PV operating point across its entire nonlinear curve.
