Abstract

This study evaluates the effectiveness of grid-connected photovoltaic systems in reducing the energy dependence of residential households. Analyzing data from 50 homes equipped with 3 to 10 kWp systems, a significant reduction in grid dependence was observed, ranging from 58% in winter to 100% in summer. System capacity showed a positive correlation with the reduction in dependence, although factors such as consumption patterns and weather conditions also have a considerable influence. Economically, the systems proved to be viable with return-on-investment times between 7.2 and 8.5 years. Environmentally, a reduction in CO2 emissions of 1,875 to 3,625 kg/year per system was estimated. The study reveals the need for customized approaches in the design and implementation of these systems, considering seasonal variability and the specific characteristics of each home. Future challenges such as intermittency management and adaptation of regulatory frameworks were identified, as well as opportunities in emerging storage and demand management technologies. The results underline the significant potential of residential photovoltaic systems to contribute to energy sustainability and climate change mitigation.
