Photovoltaic energy generation is the only method that directly transforms solar energy (radiation) into electricity. This direct conversion is the result of the effects generated by the contact with semiconductor materials such as silicon, generating the photovoltaic effect.
In its report “Analysis of Inclusion of Solar Generation in the Brazilian Energy Matrix" released in May 2012, the Energy Research Company (EPE) points out that despite natural fluctuations, such as long periods of rain that could produce temporary effects, variations between years are quite low (between 4% and 6% in arid regions and up to 10% in coastal or mountainous areas¹). The EPE recently launched an updated study on the country's solar sector and revealed that this source has a potential of 30 thousand GW in Brazil, more than 200 times higher than the current grid.
Solar energy accounted for very little in Brazil, representing only 1.3% of the Brazilian energy matrix. In April 2019, it represented 2.1 GW in 2,469 plants². Nonetheless, the 2027 Ten-Year Energy Plan (PDE)³ projects significant growth of this source, which should reach installed capacity of 8.6 GW in December 2027.
CPFL Renováveis is an early explorer of this source and has been operating a solar power plant – the Tanquinho plant in Campinas, São Paulo - since 2012. The plant has installed capacity of 1.1 MW, physical guarantee of 0.2 MWavg and its energy is sold through a contract in the Free Contracting Environment (ACL).
