Abstract

Brazil currently imports approximately 85% of its fertilisers, making its agricultural sector vulnerable to international supply disruptions and price volatility. In parallel, significant portions of the country face challenges related to energy poverty and food insecurity. Agrivoltaic systems, when coupled with localized production of green fertilisers, offer a promising pathway to simultaneously address these issues. Leveraging Brazil’s abundant solar radiation and rainwater availability, this study presents an innovative, integrated system for decentralized fertiliser production. Implemented at the Solar Energy Laboratory of the Universidade Federal de Santa Catarina, the system combines Building-Integrated Photovoltaics (BIPV) with green hydrogen (H₂) production, subsequently enabling the synthesis of ammonia (NH₃) and ammonium sulphate. The outcomes offer a scalable model for enhancing agricultural resilience and energy autonomy in Brazil and similar contexts worldwide.
