Fires linked to solar panels surge as installations increase

In the UK, fire brigades reported a significant increase in fires associated with solar panels, with 212 incidents recorded last year. This figure represents a dramatic rise from 91 fires in 2022, 131 in 2023, and 155 in the year prior. The data, obtained by business insurer QBE through the Freedom of Information Act, highlights that the majority of these fires occurred in residential properties, with 102 incidents specifically in homes equipped with solar panels. This alarming trend raises concerns regarding the safety of solar panel installations, especially as the UK government pushes for all new builds to incorporate renewable energy sources.

The analysis conducted by QBE identified the primary causes of these fires, with cabling and connectors being responsible for 49 incidents, followed by the panels themselves at 36, and battery banks at 23. The increase in fire incidents is occurring at a rate that outpaces the growth of solar panel installations, which saw 1.9 million units built last year, a 52% increase from 1.2 million in 2022. This discrepancy suggests that while the adoption of solar energy is accelerating, the quality of installation and fire safety measures may not be keeping up with this rapid expansion.

Adrian Simmonds, Risk Manager at QBE Insurance, emphasized the importance of ensuring safe installation and maintenance practices to mitigate the risk of fires. He noted that the rise in incidents is concerning, particularly as fires can spread to the wider building, posing a significant risk to homeowners. Despite these concerns, a spokesperson for the Department for Energy Security and Net Zero reassured the public that the risk of fire from solar panels is relatively low compared to other household appliances, such as cookers. They also highlighted the financial benefits of solar panels, stating that families could save around £500 annually on energy bills if properly installed.

The growing number of fires linked to solar panels raises critical questions about the balance between promoting renewable energy and ensuring public safety. As the UK government continues to advocate for on-site renewable electricity generation in new builds, it is essential to address the underlying issues related to installation quality and fire safety. The findings from QBE's research serve as a wake-up call for both policymakers and the solar industry to prioritize safety measures alongside the expansion of renewable energy initiatives.
