Experts in fire protection

The danger is hidden in the roof!

An underestimated danger is present in many roofs when installing photovoltaic systems: flammable insulation materials. If they catch fire, it can spread very quickly along the entire roof structure. The result can be serious damage to the infrastructure and high costs due to operational downtime, repairs and replacements.

PVProtect therefore uses a holistic protection concept to shield lives and property from fire damage caused by PV systems: a close-meshed network of sensors monitors the roof area below the photovoltaic system for unusual temperature increases. This allows for fires to be detected early and located with pinpoint accuracy. In the event of a fire, PVProtect automatically initiates the suppression to prevent uncontrolled spreading. Simultaneously the system alerts the emergency services and informs them of the blaze‘s exact location. People on site are also warned to enable safe evacuation of affected areas.

Four building blocks - one system

Early fire detection

  • Targeted monitoring of the roof surface below the PV systems for unusual temperature rises

  • Reliable detection of the fire outdoors using special measurement technology

  • Early detection forms the basis for fast and effective firefighting and safe evacuation of affected buildings

Pinpoint localization

  • PVProtect provides precise localization of the fire’s source through the targeted arrangement of heat differential detectors in the area of the photovoltaic modules

  • Alerts people in buildings affected by fire

  • Informs the emergency services of the exact location of the fire

Effective fire suppression

  • Fires are automatically extinguished before they can spread far and wide

  • Specially developed extinguishing nozzles enable water to be distributed over the entire area even at low operating pressures

  • Precise positioning and alignment of the extinguishing nozzles ensure effective firefighting

Reliable technology

  • PVProtect has been tested and approved for its effectiveness by VdS Schadenverhütung
  • PVProtect includes safety reserves in the system design to ensure effective firefighting at all times
  • A high level of operational safety is achieved through the use of proven technologies

Fire spread with PVProtect

  • Sensors in the heat detector cable identify the incipient fire
  • Automatic firefighting is initiated immediately
  • Extinguishing water is distributed precisely and comprehensively
  • The fire is suppressed before it can ignite the insulation material and spread over a large area

Fire spread without PVProtect

  • The incipient fire remains undetected and can spread across the roof surface
  • The fire can covertly travel along the trapezoidal sheet metal and resurface in unexpected locations
  • This may result in large-scale and devastating fire damage

Many advantages - one system

Holistic protection concept

  • Detect fires at an early stage and locate them precisely
  • Alert emergency services and people on site immediately
  • Automatically start the extinguishing water supply and fire suppression
  • Support emergency services by localizing and suppressing fires and assisting in evacuation

Comprehensive protection

  • Offers protection against devastating consequential damages from a fire
  • Helpst to minimize costs from business interruptions
  • Helps to prevent fire from spreading to the interior of the building

Sustainable system design

  • Does not require any constructional adaptations to the roof structure
  • Enables quick and easy integration during ongoing operations
  • Allows cost-effective expansion of existing extinguishing systems

Recommended by insurances

  • Tested for effectiveness and approved by VdS Schadenverhütung
  • Forms the basis for the comprehensive insurability of buildings with photovoltaic systems
  • Offers a high level of operational safety thanks to proven technologies and safety reserves in the design

Minimax makes the difference

  • First VdS-approved firefighting solution for roof surfaces with photovoltaic systems
  • Detects and suppresses incipient fires automatically
  • Localizes fires with pinpoint accuracy
  • Cost-effective expansion option for existing extinguishing systems
