Flamblocker CF7 – Fire Suppression Solution for Solar Panel and Rooftop PV Fires

Flamblocker CF7 is a high-performance, PFAS-free firefighting liquid designed to address the specific challenges associated with solar panel (photovoltaic) and rooftop fires. Operational field tests demonstrate that CF7 is highly effective in extinguishing fires located beneath and between solar panels and roof structures, including areas that are difficult or unsafe to access using conventional firefighting methods.

Test results confirm significantly reduced extinguishing times, enhanced cooling performance, and improved firefighter safety. During full-scale rooftop fire simulations, Flamblocker CF7 demonstrated such a strong cooling effect that solar panels were cooled to a safe touch temperature within seconds after flame knockdown, allowing contact with bare hands shortly after extinguishment.

Flamblocker CF7 is PFAS-free, fully biodegradable, non-toxic, and non-corrosive, and is fully aligned with current and emerging EU legislation governing firefighting foams and extinguishing liquids. It provides fire services and public authorities with a future-proof, environmentally compliant solution for solar panel fire incidents.

Flamblocker CF7 – Technical Description for Solar Panel Fire Applications.

Fire Risks Associated with Solar Panel Installations.

Solar panel (PV) systems introduce specific firefighting challenges, including:

• Limited accessibility beneath and between panels

• Heat accumulation in confined roof cavities

• Elevated re-ignition risk

• Electrical hazards and delayed cooling

• Structural fire spread beneath panel arrays

Traditional water application often struggles to penetrate these concealed spaces efficiently, leading to prolonged operations and increased risk.

Effectiveness in Concealed and Hard-to-Reach Fire Zones

Flamblocker CF7 has been operationally tested in real-life firefighting scenarios involving solar panel installations. Test results demonstrate that CF7:

• Penetrates effectively beneath and between solar panels

• Suppresses flames in concealed roof spaces

• Rapidly reduces thermal energy in the fire zone

• Shortens overall extinguishing and overhaul time

This enables effective control of fires that are otherwise difficult to reach without extensive panel removal or structural intervention.

Superior Cooling Performance

A critical performance characteristic of Flamblocker CF7 is its exceptional cooling capability. During full-scale rooftop fire simulations:

• Fire knockdown was achieved in reduced time

• Residual heat in solar panels was rapidly dissipated

• Panels cooled to a temperature safe for bare-hand contact within seconds after extinguishment

This rapid cooling significantly reduces:

• Re-ignition risk

• Thermal damage to roof structures

• Firefighter exposure to residual heat

Operational Safety and Tactical Advantages

The rapid cooling and penetration characteristics of Flamblocker CF7 support safer firefighting operations by:

• Reducing time spent in hazardous roof environments

• Limiting the need for mechanical panel removal

• Supporting faster transition from suppression to overhaul

• Improving post-fire scene control

Its non-toxic and non-corrosive formulation further reduces risks to personnel and equipment during prolonged operations.

Environmental and Health Profile

Flamblocker CF7 meets modern environmental and occupational safety expectations:

• 100% PFAS-free

• Fully biodegradable

• Non-toxic

• Non-corrosive

This eliminates long-term environmental contamination risks and supports compliance with environmental protection standards.

Regulatory Compliance (European Union)

Flamblocker CF7 is fully compliant with current European Union regulations governing firefighting foams and extinguishing liquids, including restrictions on PFAS-containing substances.

For public authorities and fire services, this ensures:

• Compliance with EU environmental and chemical legislation

• Simplified approval in public procurement procedures

• Reduced future liability related to restricted substances

• Long-term procurement sustainability

Typical Application Scenarios

Flamblocker CF7 is suitable for firefighting operations involving:

• Rooftop solar panel (PV) installations

• Residential, commercial, and industrial PV systems

• Concealed roof space fires beneath solar arrays

• Warehouses, logistics centers, and public buildings with PV installations

• Retrofit and large-scale rooftop solar projects
