Brazil recorded 245 thousand new solar energy installations in DG (distributed generation) systems in the first four months of 2025.
With this, the country now has more than 3,4 million connections to the electricity grid, with residential applications representing 83% of this total — the highest percentage since 2019, according to a survey by Soleasy.
Next come the commercial and rural sectors — both with around 8% of installations (346 thousand and 297 thousand, respectively).
The industrial sector has 47 thousand connections (1%), while the public sector is responsible for just over 10 thousand systems — equivalent to 0,3% of the total.
O study It also points out that more than 5,5% of Brazilian consumer units already have solar DG systems today.
Despite the growth in the number of connections, the installed capacity recorded a decline: the total capacity added in the first four months of 2025 was 13% lower than in the same period of the previous year.
According to Solfácil, this drop is related to the increase in the prices of photovoltaic equipment, which would have made it difficult to convert budgets into sales — especially for integrators.
In practice, this means that projects are getting smaller, according to Solfácil. The data shows that installations with power between 3 and 6 kWp already represent 47% of connections made up until April — in 2017, this range ed for 35%.
State ranking
The document published by Solfácil also reports that the state of São Paulo leads solar energy installations in the country, with 148 thousand new connections in the last 12 months.
Next come Mato Grosso (59 thousand), Minas Gerais (59 thousand), Rio Grande do Sul (48 thousand) and Bahia (47 thousand), as illustrated in the image below:
