The article presents a low‑cost I‑V curve tracer designed for solar panels, intended to be embedded in panels to optimize energy production through in‑situ characterization. The tracer is built on an open‑source platform with an embedded microcontroller, enabling rapid automatic trace generation, low power consumption, and M2M communication for data transfer. Preliminary results demonstrate the tracer’s capability to produce accurate I‑V curves quickly, validating the design methodology.
This article presents the realization of a low-cost I-V curve tracer especially designed for solar panels. The proposed design is a low-cost implementation of an I-V tracer capable of producing a number of traces automatically within a fraction of second. It is based on an open-source platform with an embedded microcontroller that integrates contemporary technologies for power consumption and measurement together with networking technologies for Machine-to-Machine (M2 M) communication. This implementation can be embedded in solar panels aiming to the optimization of solar energy production by providing an in-situ solar panel characterization system. Details about the analysis and design methodology for the developed portable tracer are presented with preliminary results.
