Photovoltaic technology is exposed to various hazards, such as fires, mechanical damage and contamination. Signaline linear heat detection minimizes these hazards by detecting thermal anomalies at an early stage. It monitors the temperature along the sensor cable, allowing for quick location of the source of the problem and preventive action. It provides continuous 24/7 monitoring and integration with fire protection systems, increasing the safety of photovoltaic installations and contributing to the development of renewable energy sources.

Threats to photovoltaic installations
Photovoltaic installations , despite their numerous ecological and economic benefits, pose certain risks that must be taken into account. One of the most serious is the risk of fire in a solar installation. It may result from short circuits, overvoltages or overheating of installation elements. Incorrect execution of electrical connections, improper selection of the photovoltaic cable , as well as mechanical damage to inverters and cables leading to short circuits, significantly increase this risk.
Another significant threat to photovoltaic panels is the possibility of electric shock. Even with low sunlight, solar installations generate high voltages, posing a danger to installers, service teams and firefighters. That is why it is so important to follow safety rules and use appropriate personal protective equipment when working on this type of installation.
External factors such as hail, strong wind or mechanical loads can lead to mechanical damage to photovoltaic modules and electrical circuits. This results in a decrease in the efficiency of the installation and, in extreme cases, may lead to short circuits and failure of the entire system.
Proper grounding, careful connection and selection of appropriate components are essential for stable and safe operation of photovoltaic installations. Irregularities in these areas can destabilize the system and lead to its failure, creating additional hazards.
Regular technical inspections, compliance with standards and guidelines for photovoltaic installations and the use of appropriate safeguards allow us to minimize the risk of the above threats. Ensuring the safety of the installation is crucial for the further development of this technology and its wide use in the energy transformation.

Signaline Linear Heat Detection System
Ensuring the safety and reliability of photovoltaic installations requires the implementation of advanced monitoring systems. One of the leading solutions in this area are heat detectors for PV installations . This innovative technology allows for continuous monitoring of the temperature along the entire length of the sensor cable, enabling early detection of thermal anomalies in the photovoltaic system and rapid localization of the source of the problem.
The key element of the Signaline LHD system is the FT-EN linear heat detection cable. Certified to EN54 Part 28, it is available in 78°C and 88°C variants. It is low smoke, halogen free (LSZH) and resistant to UV radiation and chemicals. These features make it ideal for monitoring PV installations exposed to harsh environmental conditions.
The heart of the system is the LocatorPlus locator, which detects temperature increases and emits an alarm signal. Its key function is the precise location of the alarm with an accuracy of 3% of the line length. This allows for quick identification of the source of the problem and taking appropriate corrective action.
The integrity of the detection system is ensured by the FT-EOL-EN end-of-line module, which works with the LocatorPlus-EN controller and the end unit. Optionally, the system can be equipped with UCB junction boxes, facilitating safe cable connection.
Signaline linear heat detection can be integrated with fire protection, alarm and other monitoring systems, creating a comprehensive solution for protecting renewable energy infrastructure. Early detection of thermal hazards, such as overheating or fires, allows for preventive action and minimizing potential damage.
Thanks to its advanced technology and wide range of functionalities, the LHD Signaline system is a key tool in ensuring the safety and reliability of photovoltaic installations, contributing to the further development of renewable energy sources.
Why choose the Signaline heat detection system?
Photovoltaic installations, a key element of the energy transition, require reliable monitoring and protection systems. One of the leading solutions in this area is the Signaline linear heat detection system, which offers a number of benefits that ensure the safety and efficiency of solar panels.
A key advantage of the Signaline system is its ability to detect thermal hazards early. By reacting immediately to a temperature rise above a pre-determined threshold (78°C or 88°C) at any point on the monitored cable, potential problems such as overheating or fires can be identified at an early stage. This allows for appropriate preventative measures to be taken and the risk of more serious damage to occur to be minimised.
Precise location of the source of the problem is another significant advantage of the system. LocatorPlus allows to identify the place where the alarm occurred with an accuracy of 3% of the line length. Thanks to this, service teams can quickly reach a specific area of the installation and take the necessary repair actions, increasing the reliability of the entire system.
Signaline also offers an impressive monitoring range. A single heat detection cable can monitor areas up to 1000 m long, and in some configurations even up to 3000 m. This allows for comprehensive protection of extensive photovoltaic installations, minimizing the costs associated with installing and maintaining multiple independent systems.
Resistance to external factors is another advantage of the Signaline system. FT-EN cables are resistant to UV radiation, chemicals and corrosion, which ensures reliable operation in difficult environmental conditions, often occurring in photovoltaic installation locations. Additionally, low operating costs resulting from the lack of the need for regular maintenance make the Signaline system an attractive solution for owners and operators of solar farms.
