Evaluación del rendimiento energético de 8 sistemas fotovoltaicos de 400W bajo diferentes condiciones de consumo

Abstract

This study evaluates the actual energy performance of eight stand-alone photovoltaic systems of 400 W installed in households of the rural community Masa II, Ecuador. Despite sharing similar technical configurations, the systems exhibit significant variations in operational efficiency, which are attributable to factors such as consumption profiles, maintenance practices, and user behavior. The VictronConnect software was employed to record daily energy production, while PVsyst was used to model the ideal performance under local climatic conditions. The comparison between both datasets revealed energy losses of up to 25%, mainly associated with the absence of preventive maintenance and the mismatch between usage patterns and system capacity. The findings highlight the need for a comprehensive approach that integrates technical design, continuous training, and monitoring strategies to ensure the long-term operational sustainability of photovoltaic systems in isolated rural communities.
