Resumen
El mercado de las energías renovables, especialmente el sector fotovoltaico, ha crecido
notablemente en la última década. Las instituciones de enseñanza superior son clave en la
formación de profesionales demandados por esta industria. Las prácticas de laboratorio son
fundamentales para entender los sistemas fotovoltaicos.
La caracterización eléctrica de un módulo fotovoltaico se basa en trazar su curva I-V. Se presenta
un trazador de curvas I-V innovador para uso en interiores. Emplea un convertidor DC-DC
comercial económico para representar la curva característica de un módulo fotovoltaico de baja
potencia (5 W), iluminado con una lámpara halógena. Un Arduino UNO sirve de interfaz entre la
electrónica y un programa en LabVIEW para monitorización y control.
Este estudio facilita sesiones prácticas en educación superior y la caracterización eléctrica de
módulos fotovoltaicos. Además, promueve la comprensión teórica y el desarrollo de habilidades
prácticas entre los estudiantes.

Higher education institutions play a crucial role in training qualified professionals demanded by this sector. Laboratory practices are vital for understanding photovoltaic systems. The electrical characterization of a photovoltaic module is based on tracing its I-V curve. This work presents an innovative I-V curve tracer designed for indoor use. It employs a low-cost commercial DC-DC converter to represent the characteristic curve of a low-power (5 W) photovoltaic module illuminated by a halogen lamp. An Arduino UNO acts as the hardware interface between the implemented electronics and a LabVIEW program for monitoring and control. This study contributes to the development of practical sessions in higher education and to the electrical characterization of photovoltaic modules. Additionally, it enhances theoretical understanding and promotes practical skills among students.
