he growth of the photovoltaic systems market has shown significant expansion in recent years, and this trend is expected to continue in the future. This technology, which enables the conversion of solar energy into electricity, has become a key component of global efforts to transition to sustainable energy sources. However, the rapid growth of this industry brings with it new challenges, especially in the context of security and regulation. One of the main problems that has surfaced with the mass introduction of photovoltaic systems is the increased risk of fire. Although photovoltaic systems are inherently safe, their installation and integration into existing building structures can increase the complexity of fire interventions. Namely, during some fires in the world, firefighters were forced to refrain from actively extinguishing fires due to the presence of dangers associated with photovoltaic systems, and focused on protecting the surrounding buildings to prevent the fire from spreading. The installation of photovoltaic systems brings new challenges even in the most developed countries. When firefighters intervene in places where these systems are installed, it is necessary to take additional protection measures compared to standard interventions on facilities that use electricity from the public network. This includes understanding how the system works, where key components are located, and how to safely turn off power to minimize hazards. The analysis of foreign literature and actual interventions provides a better insight into the additional dangers that photovoltaic systems represent and what protective measures should be taken. This includes specific technical guidelines, training firefighters to work in the presence of photovoltaic systems, and updating laws and regulations to ensure the safety of both installations and emergency response. It is clear that, with proper regulation and training, PV systems can be safely integrated into our infrastructure, while simultaneously contributing to sustainable development and greenhouse gas reduction goals.
