The solar industry welcomes clarity on how to minimise fire risk from solar PV systems, which in absolute terms is extremely low. “The core way to mitigate any risk is to ensure the highest possible quality in the design, installation, operation, and maintenance of solar systems.
Choices regarding the grounding of the generator and its protection devices are fundamental for a design that evaluates fire risk. The subject of the article is the analysis of the relation between electrical phenomena in PV systems and the fire risk related to ensuring appropriate fault detection by the electrical protection system.
To prevent photovoltaic fires, establish a safety inspection system and use systematic management. Regularly check the temperature at the connector if a string inverter is used.
Therefore, the reliability of PV systems is very high, resulting in a low frequency of documented fires. However, when the numbers of existing and planned PV systems are considered, even with a very high reliability and low failure rate, the potential for PV fires remains significant.
