Brazil's solar expansion spurs growth of photovoltaic roof tiles

Rising electricity tariffs and increasing environmental concerns are driving rapid adoption of solar power in Brazil. New Focus Solar Energy executives emphasize the clean, CO₂‑free generation of photovoltaic systems, noting that solar reduces dependence on hydroelectric plants that are vulnerable to droughts. Jefferson Bernardo said, “When we compare solar with traditional sources, especially thermoelectric plants, the environmental gain is direct: generation is clean, without CO₂ emissions during operation.” The sector’s growth is also encouraging new building technologies, such as solar roof tiles that combine roofing and electricity generation. These tiles embed photovoltaic cells, preserving the aesthetic of traditional clay tiles while producing power, but they cost between R$450 and R$650 per square metre (about R$50 k–70 k for a typical house) and are slightly less efficient than standard panels.

Both the broader solar market and the emerging tile technology are expected to expand as costs fall and production scales up, offering Brazil a more diversified and sustainable energy mix.
