Ana Maria Braga Revealed How She Managed to Drastically Reduce Her Electricity Bills in 2025 by Combining Residential Solar Energy with Simple Efficient Usage Strategies, Achieving Savings of Over R$ 10 Thousand
On November 13, 2025, during the program Mais Você, presenter Ana Maria Braga shared a personal experience that caught the attention of millions of Brazilians.
By installing solar energy panels on her farm in rural São Paulo, she achieved a savings of R$ 10,694.79 on her electricity bill between August, September, and October of 2025, compared to the same period in 2024.
This reduction represents 75% in savings on electricity expenses. In 2024, Ana Maria paid between R$ 4,000 and R$ 5,000 per month. By 2025, after the installation of the solar panels, the amounts dropped to R$ 1,934.63.

Solar Energy: Smart and Sustainable Investment
Ana Maria Braga’s decision to invest in solar energy was not only motivated by savings. She also highlighted the importance of sustainability and its positive impact on the environment.
During the program, she mentioned that the technology is being used in isolated communities in the Amazon, especially during COP-30, a global event on climate change.
According to experts, the investment in photovoltaic systems can range from R$ 11,000 to R$ 20,000, depending on the structure and energy demand of the residence. The financial return typically occurs between 3 to 5 years, making it a viable alternative for those looking to reduce costs and contribute to the planet.
The Real Impact of Solar Energy on the Lives of Brazilians
Although the sun shines for everyone, access to solar energy still requires investment. According to Ronaldo Koloszuk, Chairman of the Board of the Brazilian Association of Photovoltaic Solar Energy (Absolar), the cost to install solar panels in a household with three or four residents is around R$ 11,000 to R$ 12,000.
On the other hand, Patrick Schaaffhausen, CEO of the Descarbonize group — which brings together companies specializing in installation — estimates higher values: between R$ 16,000 and R$ 20,000 for families with a monthly consumption of R$ 400 to R$ 600. This amount already includes equipment, the project approved by the utility company, and complete installation.
Learn How the Installation and Energy Generation Process Works
After the installation of the equipment, the energy generated by the solar panels is used directly in the residence, which only resorts to the conventional power grid when necessary. As this produced energy is not charged, the result is a significant reduction in the electricity bill.
The time to recoup the initial investment varies according to the household’s consumption, solar incidence in the region, and the amount invested. According to Ronaldo Koloszuk, the average return is around three and a half years. Currently, several companies offer photovoltaic system installation services and provide online simulators to estimate potential savings.
The installation process usually takes between one and two days, after identifying a suitable location on the roof or property, free from shadows. According to Patrick Schaaffhausen, generally, it is not necessary to replace the wiring in the house. The connection is made directly from the existing electrical panel, requiring only specific adaptations to ensure the safety and proper functioning of the system.
For those living in apartments and unable to install solar panels on their property, there is the option to purchase energy from shared generation plants. In these cases, the consumer pays less than on the conventional bill, with a discount — or rebate — that varies according to the supplying company, according to Koloszuk.
Benefits of Solar Energy for the Consumer
Ana Maria Braga’s experience illustrates the main benefits of solar energy:
| Benefit | Description |
| Cost Reduction | Significant savings on the electricity bill, depending on the consumption profile. |
| Property Appreciation | Properties with solar systems have a higher market value. |
| Sustainability | Reduction of CO₂ emissions and lower environmental impact. |
| Energy Independence | Less dependence on utilities and protection against rate increases. |
How to Start Saving with Residential Solar Energy?
For those looking to follow Ana Maria Braga’s example, it is important to consider a few steps:
- Consumption Analysis: evaluate your average monthly energy expenses.
- Feasibility Study: consult specialized companies to check technical feasibility.
- Budget and Financing: compare proposals and check credit options.
- Installation and Approval: after installation, the system must be approved by the local utility.
- Continuous Monitoring: monitor system performance and optimize consumption.
These steps are essential to ensure that the investment in solar energy is successful and generates the savings expected.
