Roof-mounted solar panels
Reliable fire detection for photovoltaic systems
Organisations around the world are investing in their own freely available sustainable energy source by covering their roofs with solar panels. But while many perceive these photovoltaic (PV) systems as a low fire risk due to their relatively simple, non-flammable construction, that is in fact not the case: electrical wirings and connections present an added risk of fire, while the panels themselves alter fire development and hinder firefighting action. Prompt detection is therefore essential to avoid serious business interruptions and damage to the structure beneath.

Fire detection and suppression systems installed inside most buildings are not designed to detect and contain fires from outside the building. A purpose-designed system to detect incidents around the rooftop panels is essential, and SecuriHeat d-LIST is ideal: this line-type heat detection system offers a robust, reliable and quick-acting fire detection system well suited for all types of exterior environments.
Causes of fires around solar panels
- Failure of DC isolators, inverters
- Overheated cables due to poor electrical wiring and connectors
- Other equipment stored on roof (eg by contractors)
- Panels aid the growth and spread of fire beneath them and prevent water from fire hoses reaching burning materials
Challenges for fire detection on rooftops
- Isolated, unmanned location
- Open air means smoke detection unfeasible
- Varying ambient temperature, exposed to rain and humidity
- Need for early warning to prevent major damage and business interruption
Key benefits of SecuriHeat d-LIST for PV systems
- High sensitivity multi-level warning for a rapid, staged response
- Multiple sensors ensure proximity to risk points and help filter out ambient heat rises
- Sealed cable withstands all weather
- Wide operating temperature range for all latitudes and environments
- Control units being mounted in easily accessible areas inside the building
- Low maintenance requirements, low maintenance frequency and long service life
