Mechanisms such as the use of aluminum to generate solar energy contribute to the reduction of environmental impacts

The solar energy sector has been gaining exponentially new appreciators, as solar energy is a clean and renewable source. As it is a profitable and sustainable source, some industries in the energy sector, such as the metallurgy sector, have greatly supported the development of the solar energy sector, as the solar energy sector now relies on the various uses of aluminum, making it possible offering strategic advantages in this sector.
According to the May 8 publication of Portal Energia, nowadays, Brazil ranks 4th among the most developed countries by 2021 in photovoltaic electricity, with new 5.7 GW (Gigawatt) last year, 2021, according to data from ABSOLAR (Brazilian Photovoltaic Solar Energy Association), based on data from the ANEEL (National Electric Energy Agency) and data from IRENA (International Renewable Energy Agency).

According to ABSOLAR, Brazil currently has 15 GW of solar energy, approximately R$ 78.5 billion of investments and more than 450 thousand jobs created since 2012. These numbers helped to prevent the emission of about 20.8 million of tons of CO2 in electricity generation.

Functionalities of aluminum in solar energy generation

The solar energy segment includes two main types: central, consisting of large plants and/or solar parks, and distributed, referring to residential systems and also for small and medium-sized companies, with solar panels on their roofs. In these installations, aluminum is present in the construction of profiles used in solar energy panels, in the form of frames or tubular profiles.

It is worth mentioning that, with the development of recent projects aimed at the solar energy sector, it is necessary that there is a constant modernization and renovation in the electricity distribution and transmission lines. To help this system work, these distribution and transmission lines are mostly made of aluminum cables, representing a large amount of aluminum consumption.
In addition, as is well known, metals such as aluminum bring great advantages when used, such as good mechanical strength, thermal adaptability, lightness and good value for money. Such advantages are essential in solar energy systems. However, aluminum also shows a great decorative effect on the profiles and also has an excellent electrical conductivity (in the case of transmission and distribution networks).

Sustainable consequences in the use of aluminum applications in the sector

Investing in renewable sources, such as solar energy, is a growing trend towards ecologically correct, sustainable and environment protection programs. In addition to sunlight used in solar energy, there are other readily available natural sources such as wind, which uses the wind.
In this case, aluminum is added to these alternatives, especially when produced nationally, obtained by a large amount of clean energy, through the use of hydroelectric plants. Also, aluminum has a high degree of recycling, which benefits the sustainable characteristics of the industries.

The big question is that the solar sector has guaranteed a promising position in Brazil, as well as the aluminum segment, which has attracted. The country has invested in the profound use of solar technologies and has access to virtually all renewable sources.
In this way, it is necessary to continue investment in the implementation of the service of using aluminum in the production of photovoltaic electricity, in order to guarantee sustainable benefits and reduce energy consumption. And, also, it can be seen that aluminum can be a great component for the solar source sector, since it has an affordable value in relation to other metals and can also be recycled, which can lead to greater savings and strong growth in both sectors.
