Uma revisão sobre o uso da energia fotovoltaica off-grid em sistemas irrigados no semiárido brasileiro

Abstract

Photovoltaic energy has gained prominence as a viable solution in several sectors, especially in rural areas, where challenges such as water scarcity, limited access to electricity in remote areas and the need to reduce energy costs are critical. In this scenario, this study analyzed the use of photovoltaic energy by rural producers in the Brazilian semi-arid region, focusing on irrigation. The methodology was based on a bibliographic review with scientific sources, highlighting the off-grid photovoltaic system as an alternative to overcoming structural barriers. In the Brazilian semi-arid region, characterized by adverse climatic conditions and low water availability, the application of photovoltaic systems has proven essential to enable more efficient and sustainable agricultural practices. Solar energy allows irrigation systems to operate, promoting the rational use of water and contributing to increased productivity. Furthermore, the off-grid model stands out for serving isolated regions, where the expansion of the conventional electrical grid is unfeasible. The dissemination of this technology in the rural sector of the northeastern semi-arid region has a direct impact on the socioeconomic and environmental development of local communities. In addition to improving the quality of life of farmers, it reduces dependence on fossil fuels and encourages sustainable practices, essential for living in semi-arid conditions. In summary, the adoption of photovoltaic energy to support rural production in the semiarid northeastern region is of vital importance. Promotes energy security, improves farmers' living conditions and strengthens sustainable development, contributing to the socioeconomic transformation of this region
