Solar panel farm in dry Brazilian landscape

Solar photovoltaic farm in the Brazilian sertão, converting abundant sunlight into clean energy and reducing emissions.

About this subject

The Brazilian sertão, a semi-arid region covering much of the Northeast, boasts one of the country's highest solar irradiation potentials, with annual averages exceeding 2,000 kWh/m². This characteristic makes the area ideal for large-scale photovoltaic solar farms. The image depicts an extensive solar panel farm installed in this environment, where the caatinga vegetation and dry soil contrast with the blue rows of photovoltaic modules.

Solar energy in Brazil has grown exponentially since 2015, driven by energy auctions and falling equipment costs. By 2023, installed solar capacity surpassed 30 GW, with notable plants in the sertões of Bahia, Pernambuco, and Ceará. These projects generate local jobs, attract investments, and contribute to decarbonizing the Brazilian electricity matrix, already one of the most renewable in the world.

Beyond environmental benefits, solar farms in the sertão help diversify the regional economy, historically dependent on subsistence agriculture and livestock. Solar panel installations can coexist with activities such as beekeeping and controlled sheep grazing, a practice known as agrivoltaics. This integration optimizes land use and provides supplementary income for local communities.

The sertão faces challenges such as water scarcity and energy poverty in remote areas. Distributed solar energy projects, like those under the Luz para Todos program, bring electricity to isolated communities, improving quality of life and enabling access to basic services. The image, captured in the late afternoon with elongated panel shadows, symbolizes the maximum utilization of sunlight in a region long accustomed to intense sun.

Frequently Asked Questions

Why is the Brazilian sertão ideal for solar farms?

The sertão has high solar irradiation, with annual averages above 2,000 kWh/m², low cloud cover, and vast available land, maximizing photovoltaic energy generation.

Does solar energy in the sertão create jobs?

Yes, the construction and operation of solar plants generate direct and indirect jobs, from panel installation to maintenance and auxiliary services, benefiting local communities.

What is agrivoltaics and how does it apply to the sertão?

Agrivoltaics is the shared use of land for solar energy generation and agriculture. In the sertão, it allows sheep farming and beekeeping among the panels, diversifying farmers' income.
