The subsidy for those installed in homes and businesses accounted for 5.74% of the amount paid by consumers on their electricity bill in 2025 through tariff increases, according to data obtained from the (National Electric Energy Agency) portal.
According to information from the portal, last year subsidies for solar panels —which covers solar panels— totaled R$16.15 billion. In total, they represented 32% of total subsidies, which were R$54.7 billion.
The calculation to reach 5.74% takes into account the weight of subsidies on the electricity bill, which was 17.96% in 2025, according to data available on the portal last Friday (9). In 2024, the percentage was 3.27%, while in the previous year it was 2.29%.
Subsidies for distributed generation are criticized by some experts, who cite the fact that consumers with lower purchasing power pay on their electricity bills for the benefit that is granted to those who have the capacity to install solar panels — which can cost around R$15,000 for small properties.
Last year, the Ministry of Finance tried to bring forward the end of the benefits granted for distributed generation, which are valid until 2045. According to the rules, consumers who requested the connection of solar panels until the beginning of 2023 do not pay for the use of the distribution network. They also have full compensation for excess energy injected into the system.
