Solar Panel Fires: Are Risks Rising in Europe?

Recent fires, including one that destroyed a hospital ward in North Yorkshire, England, on July 8, have led to scrutiny of solar panels. Although 15 patients were safely evacuated, the incident follows similar blazes at primary schools, prompting some schools in Suffolk to switch off their panels. Despite these events, solar photovoltaic (PV) technology is a dominant force in Europe's renewable energy landscape, making up 23.4% of the EU's renewable electricity consumption in 2024.

The overall risk of solar panel fires is considered extremely low, despite the increased media attention due to the technology's widespread adoption. Dutch research indicates that between 2015 and 2018, fewer than 0.014% of residential solar installations in the Netherlands were involved in fires. Similarly, German data from 1993-2013 suggests a fire incidence rate of 0.006%.

Studies across four European countries show fire incident rates of 5-22 per 100,000 installations, with Slovenia reporting higher numbers potentially due to varying data collection methods. The majority of solar-related fires (68%) remain contained within the PV equipment, with only a small percentage causing significant spread or destroying buildings entirely. The European Commission states that fires are rare and typically linked to installation errors or faulty components, not the solar technology itself.

To mitigate risks, stringent EU regulations ensure panels meet technical requirements, and installers must be certified. Homeowners are advised to use accredited installers, ensure proper mounting of inverters, and schedule regular professional inspections, especially after extreme weather events.
