The October issue of “FotoVolt” is online. The article “Software for calculating metallic structures for PV systems”, on page 54, describes and compares finite element analysis software and structural analysis software. In photovoltaic solar plants, the choice of software to size the structures directly influences the results of the calculations. See on page 38 article “H2 for energy storage: applications, standards and connection to the electrical grid”, which revisits concepts and addresses the integration of hydrogen in the electrical sector. The successful implementation of hydrogen storage must overcome challenges associated with production, storage and conversion, in addition to observing safety and transportation standards. Furthermore, on page 58, the news “Partnership between company and university will test and develop PV technologies”, about Mackenzie and Huawei opening a laboratory for safety tests on inverters and a solar plant to produce energy generation prediction models based on artificial intelligence. The initiative also structures firefighter training and courses for students. This issue also brings the update “Foundation pile for solar plants”, “Cleaning machines & services for PV plants” and “Monitoring system for photovoltaic power” buyers’ guides.
