What is it about?
This work explores the economic feasibility of photovoltaic (PV) systems combined with battery storage for residential self-consumption in low-voltage distribution networks. Eight scenarios were analyzed, including grid injection, net-metering, and battery use. Results show that while self-consumption can be financially beneficial, current battery costs still limit profitability. However, future price reductions and regulatory support may turn PV+storage into a highly viable solution for prosumers.

Why is it important?
With growing interest in clean energy and energy independence, understanding whether home PV systems with batteries are financially viable is essential. This study provides practical insights into which configurations are currently profitable, and under what conditions. The work is especially timely given rising electricity prices, advances in battery technologies, and the evolution of prosumer-friendly policies. It supports decision-making for households, policymakers, and energy planners working to accelerate the energy transition.
Perspectives
This research reflects my personal interest in bridging technical innovation with real-world impact. As an engineer and academic, I find it essential to evaluate how emerging energy technologies perform economically for end-users, not just technically. The results reinforce the importance of supportive regulatory frameworks and further cost reductions in battery systems to make energy self-consumption a widely accessible solution.
