Photovoltaic systems have become a significant source of renewable energy in Slovenia, but their installation over time increases fire risks. The purpose of this thesis is to address the fire safety of photovoltaic systems on Slovenian farms and review guidelines and legislation to see if they sufficiently cover the fire safety. The research was based on review of fire reports from System of reporting interventions and accidents (SPIN) between 2015 and 2024 and on analysis of the guidelines and legislation. It was found that 15 fires occurred at facilities with photovoltaic systems during this period, three of which were on agricultural facilities. For one of these fires, the cause was the photovoltaic system. The analysis showed that legislation and guidelines sufficiently cover fire safety, but it is essential that they are consistently followed at the installation of the system. Some guidelines are already outdated and need updating. Key measures to reduce fire risk are also presented, such as regular and thorough inspections, the installation of arc fault detectors and additional fire protection of the roof.
