Faced with growing concerns about power outages, particularly in remote areas or areas with poor infrastructure, residential consumers have been seeking solutions that guarantee autonomy and stability in supply.
In this context, energy storage systems – integrated with photovoltaic generation – are increasingly gaining ground in homes. According to a survey carried out by Greener, the demand for BESS (Battery Energy Storage System) equipment grew by 89% in 2024 compared to 2023.
In all, around R$22,5 billion should be invested by 2030 in the Brazilian battery market among consumers. One of the reasons given that helps to understand this growth is the reduction in the price of technology: batteries recorded a 20% drop in FOB price, with the reduction in the value of the cell being the main factor.
According to consulting, by 2025, the price is expected to fall by another 22% and reach the range of US$ 90,00/kWh. By 2030, the price is expected to continue falling and reach US$ 64,00/kWh. With the downward trend in costs and the increased awareness of the benefits of energy autonomy, many families are opting for photovoltaic systems with batteries, thus keeping essential equipment running even during power grid failures.

Alexandre Serafim, from São Paulo, for example, is one of these consumers. He saw technology as a way to ensure peace of mind in his home located in São Bento de Sapucaí, in the interior of the state of São Paulo. Often used for remote work, the residence needed a structure that would function reliably, even in situations of electrical instability.

Dear Sirs, there is no doubt that energy storage via batteries is already a thing of the past and here we are waiting for regulation of this sector, which is taking a long time. We know that the problem of intermittency is an important issue that can be easily overcome by this alternative.
