Challenges and Solutions in the Certification and Efficiency of Photovoltaic Modules in Brazil: Perspectives from the Intersolar 2024 Conference

The Intersolar 2024 Conference highlights the global transition to renewable energies, with a focus on the photovoltaic sector. Leandro Michels emphasizes effective solar practices, while Sérgio Roberto Silva dos Santos discusses the degradation of solar modules - still little explored - based on his research. The conference promotes cross-sector innovation between distributed generation and electric mobility in Latin America. The text highlights the need for accurate information on the efficiency and durability of photovoltaic systems, pointing out discrepancies in technical specifications versus actual performance tested by IV curve machines. Current standards help prevent these problems; however, there is a lack of information on the degradation rates provided by manufacturers to end consumers. In Brazil, regulatory challenges are exacerbated by the lack of adequate laboratory infrastructure for thorough testing of commercialized local modules. A confusing update of Inmetro's ordinance on photovoltaic inverters raises regulatory issues due to the erroneous exemption of FCI protection above 120 volts and localized shortages in accredited laboratories for essential tests such as the electric arc test which only a small fraction passed without necessary adjustments.
