“…Its location in the tropics has potential for PV electricity generation throughout the year, especially at the areas located in the north-east and mid-west. Brazil receives average horizontal solar radiation in the range of 3.5 to 6 kWh/m 2 .day, which is higher than most European countries with an established PV installed capacity [49,50] (Table 1). The PVSS in this study are located in several Brazilian regions, from the south to the northeast of the country, representing the climate diversity of the country.…”

“…Brazil is a country of great territorial extension with a wide variety of climates and variation in the annual solar irradiation at different regions, as shown in Figure 7. [49]. Its location in the tropics has potential for PV electricity generation throughout the year, especially at the areas located in the north-east and mid-west.…”

The energy sector and electricity generation in particular, is responsible for a great share of the global greenhouse gas (GHG) emissions. World electricity generation is still largely based on the burning of fossil fuels. However, Brazil has already a very low electricity carbon intensity due to the country’s large hydropower capacity. In countries with low grid carbon intensities such as Brazil, the investment in photovoltaic solar systems (PVSS) even if it is cost-effective, might become challenging as any new generation competes essentially against other renewable generation and the carbon offset is not a key driver for investment anymore. This study builds further upon that case to examine if national renewable energy incentives could actually lead to an increase of global net carbon emissions from the installation of PVSS in countries with a low grid carbon intensity. The study presents a life cycle analysis (LCA) of ten photovoltaic systems representative of the different operational conditions in regions across Brazil. It was found that the average energy payback time of the studied PV plants is between 3 and 5 years of operation. This result shows the feasibility and viability of such investments in the Brazilian context. When the LCA was integrated into the analysis though, the results showed that the “local” direct emissions avoidance from two out of ten studied PV plants would not manage to offset their “global” life cycle emissions due to the 2020 projected Brazilian grid emission factor which is already low. It is important to recognize that public policies of unrestricted, unconditional stimulus to photovoltaic systems investment might not help towards reducing global net emissions when the PV systems are installed at countries with a low carbon emission electric matrix. That is also something to consider for other countries as the carbon intensity of their grids will start reducing at levels similar to Brazil’s. It is likely that in the near future, the real net carbon offset achieved by PV systems at the global level will be largely defined by the manufacture procedures and the production’s carbon intensity at the country of origin of the PV panels.

“…In this case, there would be an expansion of the sustainability capacity of the Brazilian electric sector, that is, following this strategic option, the equation of the Brazilian energy matrix would tend to become even more sustainable. According to Pereira (2017), "the Northeast region has the greatest solar potential, with an average value of the daily total of global horizontal irradiation of 5.49 kWh/m² and the normal direct component of 5.05 kWh/m²". The Southeast and Midwest regions present daily totals close to the global horizontal irradiation around 5.07 kWh/m 2 .…”

This article examines the possibility of using solar energy as a viable alternative, necessary to diversify the country’s energy matrix under the potential the Northeast presents. The approach is made with a view to highlighting clean and renewable energy and a global effort to preserve the environment, embodied in treaties and legal instruments of International Law. The central core is the idea of sustainability. The methodology approach is qualitative, in which legal and doctrinal surveys will be used in the legal literature. The text is divided into an introduction that gives an overview of the subject studied, then subdivided into 3 (three) specific topics that discuss the search for alternatives to the Brazilian energy matrix, considering about solar energy and, finally, the regulation of that energy. In the research, the economic viability is verified when the installation expands through this energy matrix, as well as the incremental benefits generated to the environment, in addition to the cost savings in the productive sector.

“…Desta forma, a informação sobre o recurso solar é a variável de maior importância no desenvolvimento de um projeto de sistema de aproveitamento da energia solar. Para que se torne viável financeiramente um projeto fotovoltaico, em média, a radiação solar exigida é de no mínimo 3 a 4 kWh/(m 2 .dia), Lorenzo (2006); Pinho e Galdino (2014); Pereira et al (2017); Babar et al (2019).…”
