The September issue of “FotoVolt” is online. The special coverage “TSESA consolidates itself as the epicenter of energy transformation in Latin America”, on page 38, shows that, with its three exhibitions and parallel conferences – Intersolar, which reached its 10^th edition, in addition to Eletrotec+EM Power and ees –, The smarter E South America brought together 50 thousand visitors in São Paulo, from of which 2500 participated in the conferences. See the exhibition coverage. Read on page 28 the article “Green hydrogen and the free market will boost the growth of solar energy”, showing that the opening of the energy market in Brazil and the imminent evolution of green hydrogen at a global level create a favorable scenario for the expansion of solar generation projects in the country. Expectations are that the source be the main source of the national electrical matrix by 2050. Furthermore, on page 56, the article “Design of the grounding system for a large PV power plant”, showing how geophysics knowledge was applied to solve an electrical engineering problem, a pioneering approach for determining a geoelectric model compatible with large-area PV power plant. This issue also brings the update “Prefabricated substations”, “Solar tracking systems” and “Solar Carports” buyers’ guides.
