Solar radiation in the less sunny region of Brazil is 40% larger than in the sunniest region of Germany, for example.

Due to constant droughts, energy crises in the electric sector and the demand for the diversification of the energy matrix in the country, Brazilians are increasingly seeking information on alternative energies. One of the most suitable systems to take advantage of this energy is the photovoltaic. To get an idea of ​​this potential, one hour of sunshine on Earth’s surface contains more energy than the planet uses in a year.

According to the National Electric Energy Agency (ANEEL) by 2024, some 1.2 million solar or more generators are expected to be installed in homes and companies throughout Brazil, accounting for 15% of Brazil’s energy matrix. By 2030, the market for photovoltaic energy should be at the value of around R $ 100 billion.

The country has great potential to move this segment. Solar radiation in the less sunny region of Brazil is 40% larger than in the sunniest region of Germany, for example, which is one of the world leaders in the use of photovoltaic energy. To take advantage of this potential, the price of kWp – the energy measure associated with photovoltaic cells – is reducing and in the coming years the challenge will be to open new lines of credit and financing. The trend is for more government programs and business models to emerge, making the process more accessible.

“Brazil has a huge potential. Europe has 88GW of photovoltaic energy while Brazil has less than 1GW installed, that is, it represents only 0.02% of the potential of the Brazilian energy matrix. But this system is increasingly accessible in Brazil. According to ANEEL, by the year 2024, around 1.2 million solar generators should be installed in homes and companies throughout Brazil, “explains Martin Drope, director of Fronius Solar Energy Division. With almost four years of operation in Brazil – as of resolution 482/2012 – the system guarantees to all – residential, commercial or industrial public – that opt ​​for solar energy, discounts on the electricity bill. “That is, if the system generates more energy than it consumes, surplus energy will be injected into the public grid. This measurement is performed through a two-way power meter – provided by the local utility – which will quantify the injected kilowatt-hours of solar energy. This surplus will be analyzed and calculated so that consumers receive a discount on their electricity bill, “adds Drope.


It is important that the consumer is aware when choosing the products to make the installation, because it is a system with a duration of at least 20 years. “Photovoltaic energy is an extremely new technology in Brazil, but its installation is easy and fast. The system can be installed on residential or commercial roofs, near or directly in the place where the energy is needed. That is, this system is independent of that generated in large central hydroelectric facilities or large wind farms. To install a photovoltaic system in a residence, the investment value is around $ 18 to 22 thousand. With expected return in seven or eight years, “says Martin.
