The world has witnessed a shift from the use of fossil fuels for domestic and industrial applications. Nigeria has not been an exemption. Among the renewable energy currently being exploited and utilised for domestic applications is solar energy, consisting of photovoltaic (PV) systems: solar panels, inverters, lithium batteries, and other accessories. Solar power systems for homes and business premises are increasingly popular in Nigeria to mitigate the impact of the long-time power shortage from the national grid. As the country embraces solar power for its clean energy benefits, it’s crucial to address potential risks, particularly the concern of fire hazards associated with solar systems. Currently the number of fire incidents involving photovoltaic (PV) systems is increasing as a result of the strong increase of PV installations. This paper discusses the intricacies of solar fire hazards, understanding the risks, identifying preventive measures, and emphasising the importance of quality solar installations. It is found that arcing, hot spots, weather conditions, improper installations and maintenance, and mechanical and electrical system failures are the main causes of solar PV fire incidents. Generally, there are no accredited or approved vendors for solar panel installations and no specific legal framework for solar energy utilisation in Nigeria. Furthermore, there is no insurance coverage for both lives and properties in the event of fire accidents resulting from solar panels. Therefore, it is expected that the study would be a useful guide for manufacturers, installers, and professionals to build upon and improve understanding of the causes, effects, and prevention of solar electric fire incidents in residential, industrial, and commercial applications.
