Say goodbye to high energy bills. Discover everything you need to know to generate your own electricity and the time it takes to get a return on your investment in solar energy.
According to a study carried out by greener consultancy, investing in residential solar energy can offer a quick recovery of invested capital in certain Brazilian states. In places like Mato Grosso, Alagoas and Piauí, the Average time for return on investment in solar energy, also known as payback, varies between 2,6 and 2,7 years. Therefore, owners of Photovoltaic systems can begin to enjoy the economic benefits of their investment in a relatively short period of time.
States where the return on investment in solar energy is longer
On the other hand, in states such as Amapá, Paraná and Roraima, the return on investment in residential solar energy can take more than four years to pay off. In Santa Catarina, for example, this period extends to more than 5 years. These discrepancies reflect a variety of factors, including local energy infrastructure, government policies and weather conditions.
A Greener analysis considers residential systems of 4 kWp (kilowatt-peak) and takes into account several aspects, such as installation time, start of system operation, tariff adjustments and the price of equipment. This holistic approach offers a comprehensive view of the residential solar energy landscape across Brazil.

It is worth mentioning that, on average, there was a 25% reduction in the return time on investment in solar energy between January 2023 and January this year across the country. This is directly linked to the drop in the price of residential photovoltaic systems, which went from an average of R$17.560 to R$12.680 in this period. This cost reduction makes solar energy a more affordable and attractive option for consumers.
Is it worth installing solar energy systems at home?
Installing solar energy at home can vary significantly in terms of costs, depending on several factors, such as the size of the system, the efficiency of the solar panels, geographic location, available tax incentives and the company hired to carry out the installation.
Os painéis solares They are installed in areas exposed to the sun, such as roofs, where they transform sunlight into energy through the photovoltaic effect.
Generally made of silicon cells, these panels generate an electrical current when exposed to sunlight. When the solar system generates more energy than it consumes, the surplus goes back to the electricity grid, generally resulting in credits on the electricity bill, further increasing the return on investment in solar energy.
On average, a Brazilian family with four people, living in an urban area, would consume around R$2023 monthly in electricity in 210. The value is equivalent to 280 kWh per month, according to electrical engineer and energy efficiency specialist Gabriel Migliomi.
For professionals, the initial investment for a family of this size is R$25. According to information from the photovoltaic system franchise company, Portal Solar, a professionally installed solar system in Brazil, capable of supplying monthly energy consumption of R$500, has a cost that varies between R$20 and R$35.
What is needed to install solar energy?
It is essential to hire a specialized company to request a quote for installing solar panels. It is important to provide the exact dimensions of the roof or installation location, as well as a recent copy of the energy bill, so that the average consumption can be calculated correctly.
Once the site is prepared, proceed with the mounting of solar panels. Furthermore, the contracted company can offer assistance with the necessary bureaucratic procedures, which may vary according to the region of the country.
