Faulty Installations Fuel Fires: Solar Panel Safety Concerns Rise in France

A series of fires linked to rooftop solar panels across France has sparked public anxiety, prompting questions about the safety of the increasingly popular technology. Incidents ranging from a partial house fire in Normandy to a warehouse blaze in Gard and a school roof fire in Gers have fueled concerns. However, experts emphasize that the solar panels themselves are rarely the direct cause of the fires.

Industry professionals point to installation and operational errors as the primary culprits. A common issue arises when panels are partially shaded by chimneys or trees. This shading can cause the system to shift from generating electricity to absorbing heat, leading to overheating and the creation of "hot spots" that can ignite. Faulty electrical connections, substandard cables, and incorrect assembly also contribute significantly. The high-current direct-voltage systems used in solar installations mean that even minor loose connections or damage can lead to overheating and fires.

Compounding these issues, some homeowners opt for cheaper, less experienced installers to save costs, especially as government subsidies for solar power in France decrease. Some even attempt DIY installations using online guides, a practice experts deem extremely dangerous. Professionals stress the importance of choosing reputable, certified companies with proven experience over those offering the lowest prices. Regular maintenance, including cleaning panels at least annually, is also crucial to prevent localized overheating from dirt accumulation.

Regarding insurance, most policies cover fire damage from solar panels, provided homeowners have an appropriate fire insurance plan. However, it is essential to notify insurers before installation and retain all maintenance records, installation documents, and evidence in case of an incident. If the fault lies with the installer, they may be held liable for compensation. Despite the recent fires, experts maintain that solar technology remains safe when installed correctly and maintained diligently.
