The Vatican’s solar shift is a culmination of a political and spiritual mission years in the making. In 2024, the late Pope Francis issued an apostolic letter ordering the construction of an agrivoltaic solar plant to supply the Vatican with energy from Santa Maria di Galeria. On the same site, the new solar infrastructure now stands.
This is not just about rooftop panels; it’s about how science, sustainability, and faith can coexist and set the pace for the rest of the world to follow. Vatican City is powered by solar. On May 29, 2025, the Vatican City officially transitioned to solar power, marking a significant shift in the European energy landscape.
This project was carried out by ACEA, an Italian utility company, which installed systems to meet all of the Vatican’s energy demands. What makes this significant is not the size, but that Vatican City is only 0.49km², and there was no loud campaign, no press tour, just action set in stone and implemented.
“Fratello sole” or “Brother Sun” was Pope Francis’ Apostolic Letter that detailed how solar power is an invitation for people around the world to make lifestyle changes to counter global warming and the “pervasive” use of fossil fuels.
Our standardized solar power and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
