Brazil is gearing up for a solar energy revolution: the first battery auction in 2026 will store solar energy for nighttime use, boosting a market that already invested R$ 40 billion in 2025 alone, across Brazil
Fueled by investments of around R$ 40 billion and the addition of 11,4 gigawatts by 2025, the Brazilian solar energy market ends the year with 65 GW installed and consolidates itself among the largest in the world, generating almost 400 jobs and attracting new projects.
Now, with the regulation of battery storage by Law 15.269/2025 and the first Capacity Reserve Auction scheduled for April 2026, the country is preparing to present these solutions at SNEC PV & ES LATAM. in São Paulo, between March 24 and 26, 2026, immediately following the giant SNEC edition in Shanghai, held between June 11 and 13, 2025.
Battery auction inaugurates new phase of the electricity grid.
Following the approval of Law 15.269/2025, which regulated energy storage in batteries, the Capacity Reserve Auction, the first Brazilian auction dedicated exclusively to contracting power from batteries, is scheduled for April 2026.
These storage systems will ensure the availability of energy produced by solar and wind power plants precisely during periods of low production. unlocking investments and providing greater security to the electrical system.
With the ability to store energy on a large scale, the system operator gains the flexibility to meet peak consumption, reduce the use of more expensive sources, and make the energy matrix even cleaner.
The hope is that the auction will usher in a new phase for solar energy in the country, connecting renewable generation, grid stability, and new business models.
The use of batteries in conjunction with solar power generation will not be limited to large, centralized power plants.
As devices become more affordable, strong growth is expected in residential and commercial installations, giving consumers more autonomy.
In other countries, systems that combine solar panels and batteries already allow families and businesses to… Reduce your electricity bill and have protection against power outages..
The trend is for Brazil to follow this path, with integrators, manufacturers, and investors taking advantage of the new regulatory framework to offer complete solutions, from rooftops to batteries installed in garages, condominiums, and small businesses.
SNEC PV & ES LATAM transforms São Paulo into a global showcase.
Between March 24 and 26, 2026, São Paulo will host SNEC PV & ES LATAM, the Latin American edition of the world’s largest solar energy event.
Over three days, the public will be able to learn about trends across the entire production chain of the photovoltaic solar sector. including solutions for electric mobility and battery energy storage.
Organized by NürnbergMesse Brasil and Oakstream, the trade fair and congress are expected to attract at least 10 people.
The program includes discussions with renowned experts at a high-level technical congress, which will address regulation, business models, battery technologies, and the role of solar energy in the energy transition.
More than 100 exhibitors at a trade fair dedicated to solar energy and batteries.
The SNEC PV & ES LATAM exhibition area will bring together approximately 100 exhibitors.
The main manufacturers of photovoltaic equipment, such as solar panels and inverters, have confirmed their participation, as well as developers of centralized and distributed generation projects.
Companies focused on the markets for energy storage with batteries, electric mobility, smart grids, and infrastructure will also participate.
The expectation is that many of these players will use the event to launch products, announce partnerships, and… to present solutions specifically designed for the new battery market opening up in Brazil..
From SNEC Shanghai to the Latin American debut of the fair.
The SNEC in Shanghai, China, has been held since 2007 and has established itself as the world’s largest solar energy event.
The 2025 edition took place between June 11 and 13 and brought together around 3,5 exhibitors, attracting more than 500 visitors.
The holding of SNEC PV & ES LATAM in São Paulo marks the first edition of the trade show and congress outside of China.
The fact that Brazil was chosen for this Latin American debut reinforces the importance of the national solar energy market., which has been attracting the attention of global technology, finance, and services companies.
2025 figures confirm the strength of solar energy in Brazil.
Data from Aneel shows that, throughout 2025, Brazil added 8,4 GW in small and medium-sized residential and commercial systems, in so-called distributed generation, and another 3 GW in large centralized generation plants. Together, these new solar energy installations represented investments of around R$ 40 billion.
This progress also resulted in the creation of nearly 400 jobs and led the country to end 2025 with 65 GW of accumulated operational capacity from photovoltaic sources.
With these numbers, Brazil remains among the world’s leading solar energy markets., occupying a prominent position alongside China, the United States, and India, and naturally qualifying to host the first international edition of SNEC.
