Together, the four states that make up the southeastern region of Brazil; São Paulo, Minas Gerais, Rio de Janeiro and Espírito Santo, comprise 45.9% of all photovoltaic systems in the country.

The data are from ANEEL (National Agency of Electric Energy), which regulates the segment of distributed generation, in which consumers produce their energy through their own generators and exchange it with the electricity grid.

Currently, more than 90 thousand Brazilians have already adopted this model in their homes and companies, attracted by the economy in the account of light and other advantages of self-generation.

Solar photovoltaic systems have dominated the segment since its inception in 2012, and today they are concentrated in a greater number in the states of the Southeast region.

Minas Gerais comes first, leading the entire national territory as the largest representative of the technology, with 18,477 systems and more than 19% of all installed national power.

In second place comes São Paulo with its 15,698 connected systems, accounting for 12.57% of the photovoltaic power distributed in the country.

In smaller proportions are the states of Rio de Janeiro and Espírito Santo, with 5,267 and 2,064 systems, respectively. Together, the four states account for 38.16% of the national distributed solar generation.

Among the reasons for this leadership are the incentives offered for distributed generation in these states, especially in Minas Gerais, first to exempt ICMS from the solar energy produced.

Along with other factors that drive more Brazilians to invest in solar panels, such as solar power lines and falling technology prices, these favorable laws make it easier for consumers who are tired of high light bills.

And growth this year remains strong in the region, which accounted for 14,431 of the 31,993 connections in the first half of 2019, a year in which the national market is expected to move around R $ 5.2 billion, according to estimates by ABSOLAR (Brazilian Solar Photovoltaic Energy Association ).
