Solar panel farm in dry Brazilian landscape

Solar photovoltaic farm in the Brazilian hinterland, with panels harvesting renewable energy at twilight.

About this subject

The Brazilian sertão, a semi-arid region covering much of the Northeast, has become a strategic hub for photovoltaic solar energy generation. With annual solar irradiation averages exceeding 2000 kWh/m², the sertão offers ideal conditions for large-scale solar farms. The image depicts one such solar farm at twilight, a time when energy production is still significant, but residential and commercial demand begins to rise, helping to balance the load on the electrical grid.

The installation of solar parks in the sertão has transformed the local economy, creating direct and indirect jobs, and reducing dependence on fossil fuels. Brazil currently has over 10 GW of installed solar capacity, with projections of reaching 25 GW by 2030. Photovoltaic panels use silicon cells to convert sunlight into electricity through the photovoltaic effect, with no pollutant emissions.

Beyond environmental benefits, solar energy contributes to the country's energy security, especially in remote areas of the sertão where grid expansion is costly and complex. Many solar plants are integrated with battery storage systems, enabling continuous supply even at night. The twilight sky, with its orange hues, symbolizes the transition to a cleaner, more diversified energy matrix.

Frequently Asked Questions

Why is the Brazilian sertão ideal for solar energy?

The sertão has high annual solar irradiation, above 2000 kWh/m², and low cloud cover, maximizing photovoltaic energy generation.

What is Brazil's installed solar capacity?

Brazil surpassed 10 GW of installed solar capacity in 2023, with a target of 25 GW by 2030, driven by farms in the sertão.

How does solar energy benefit the local economy of the sertão?

It creates jobs in construction and maintenance, attracts investments, and reduces energy costs for rural communities.
