In this bachelor's thesis, I examined the fire risk associated with photovoltaic systems. I
presented the history of the development of solar cells, their structure, types, operating
principles, and key components that may pose an increased fire hazard. Particular
emphasis was placed on proper installation and assembly, as well as on the most common
causes of fires. I also presented technical and organizational measures and firefighting
procedures.
Using FMEA, I assessed the fire risk of individual components and identified the most
critical hazards through a hypothetical example of a photovoltaic system. I found that the
greatest fire risk is associated with the DC side of the system, particularly poorly executed
connections, damaged DC cables, and improper installation, which can cause electric arcs
and consequently lead to fire. Proper installation of solar modules, regular maintenance,
and system inspections are therefore very important. I also found that power optimizers
improve fire safety by enabling voltage reduction and better system monitoring.
