Solar storage systems became 30% cheaper this year, says Solfácil

Falling cost of lithium batteries and rising demand drive price reductions, according to company survey

Hybrid solar energy storage systems saw a 30% drop in average prices between January and August this year, according to a study by Soleasy.

According to the survey, the reduction is a direct result of the drop in costs lithium batteries, the main component of these systems, and the increased demand for these systems.

According to the data, the price of lithium batteries plummeted 43% in the period, while hybrid inverters became 26% cheaper. 

Equipment such as inverters from the ES G2 and ET lines, capable of operating in on-grid and off-grid mode without the need for adaptations, are among the most sought after. 

LiFePO4 lithium batteries, recognized for their durability and greater efficiency compared to lead-acid batteries, have also been gaining ground in the Brazilian market.

The growing demand for storage solutions is also directly linked to a scenario of rising electricity costs and technical challenges, such as the “flow reversal challenge” in distribution networks. This movement has intensified competition in the sector and accelerated the fall in prices.

The search for hybrid systems has grown significantly over the same period. According to Solfácil, the main advantage of this technology is the combination of efficiency, energy security and autonomy, especially in a scenario of instability in the supply of electricity. 

“Consumers have seen hybrid systems as a robust solution to ensure uninterrupted energy and save money in the long term. The trend is for hybrid solar energy systems to become an increasingly viable option for those seeking not only savings but also greater control over consumption and generation of electricity,” says Brainer Martins, COO of Solfácil.
