It is with great enthusiasm that we present the 23rd edition of Canal Solar Magazine, full of information and insights about the solar energy market and its innovations. Our cover this month highlights a topic of growing relevance: “Sodium-ion batteries: a promising alternative for the market”. We explore how these batteries can transform the energy storage market, emerging as an alternative to lithium-ion, nickel, lead and cobalt batteries. According to consultancy Roland Berger, sodium ion batteries could represent around 30% of the market by 2040. The late professor Marcelo Villalva had already made a discussion about the diversity of batteries, highlighting the potential of sodium, which is more abundant and cheaper. In this edition, journalist Wagner Freire brings the report “Solar energy in 2024: challenges and opportunities in an evolving market”. Even with more moderate growth compared to previous years, solar energy continues to consolidate itself as a vital source in Brazil's electrical matrix, representing 17% of installed capacity. Projections indicate a significant increase in installed power, highlighting the crucial role of distributed generation. Another topic discussed in this edition is the challenges and prospects of subscription solar energy in Brazil. Journalist Yvana Leitão interviewed sector experts who discussed the advantages and challenges of this model.
