Following a fire at Malton Hospital in North Yorkshire on 8 July 2026, which destroyed a building and required the evacuation of 15 patients, UK authorities and schools have intensified safety reviews. In Suffolk, officials deactivated solar panels at approximately 80 schools as a precaution following three similar fires in English primary schools over the past year.

While European data from Germany and the Netherlands suggests photovoltaic fires are extremely rare—affecting less than 0.01% of installations—new research from insurer QBE indicates that solar panel fires in the UK have increased by 133% since 2022. During this period, installations grew by 52%, reaching over 2 million by May 2026, while fire service call-outs rose from 91 in 2022 to 212 in 2025. Residential properties have experienced the highest number of incidents.

Technical analyses attribute most incidents to installation errors, poor wiring, or substandard components rather than inherent panel defects. QBE identified DC cabling and connectors as the leading cause of fires in 2025, followed by the panels, inverters, and battery banks. Experts have also warned of additional risks from lithium-ion battery storage due to potential thermal runaway. To mitigate these risks, authorities recommend using certified installers, employing UL-listed components, mounting inverters on non-combustible surfaces, and conducting regular maintenance inspections.

## Timeline

### 2026-08-10: UK solar panel fires rise 133% amid increasing installations

Solar panel fires in the UK have risen 133% since 2022, outpacing installation growth. Experts note that while sunlight drives generation, extreme heat can actually reduce panel efficiency.
