Fires in photovoltaic panels are relatively rare compared to other sources of domestic or industrial fires. PV panels themselves are designed to be safe and fire-resistant.

However, electrical problems, system failure, improper installation, inadequate maintenance, or environmental factors can contribute to the risk of fire.

According to statistics, it is estimated that by 2025 there will be 64 fires in photovoltaic panels in California alone, with estimated costs of more than 18 million (US $).

As the installation of structures with several hectares of panels multiplies in Portugal, and companies allocate part of their investment in the installation of photovoltaic panels, it is appropriate to alert to the possibility of fire occurrence in these systems.

A fire detection and extinguishing system for photovoltaic panels is essential to ensure the safety and protection of these solar energy systems.

There are different components that can be included in a fire detection and extinguishing system for photovoltaic panels.

Here are some of the most commonly used elements:

1. Fire detection system: this may include heat, smoke or flame sensors, installed on the PV panels or in nearby areas. These sensors are designed to identify any sign of early-stage fire.

2. Alarm system: when the detection system identifies a potential fire, it activates an audible or visual alarm to alert area occupants and initiate the response process – fire suppression.

3. Fire suppression: there are different fire suppression methods that can be applied. Given the specificity of the equipment and the fire, we advise the use of alternative extinguishing agents other than water.

These systems can be activated automatically by the detection system or manually by means of a control panel. These systems release an extinguishing agent to suppress the fire.

4. Power disconnection: to ensure the safety of rescue teams and reduce the risk of electric shock, it is important that the fire detection system includes devices that automatically disconnect the power to the photovoltaic panels in the event of a fire.

It is important to note that the implementation of a fire detection and extinguishing system on photovoltaic panels should follow local standards and regulations, as well as the guidelines of the manufacturers of the components used. In addition, it is recommended that a qualified professional be consulted to properly design and install the system, taking into account the specific characteristics of the site and the photovoltaic panels.

It is recommended to follow best practices for installation, maintenance, and compliance with standards and regulations to minimize risk and ensure the safety of photovoltaic systems.

Our system is an example of a fire suppression system designed specifically for photovoltaic panels. This system is an automated fire suppression solution developed to detect and extinguish fires that may occur in photovoltaic systems.

It consists of a series of heat and smoke sensors strategically placed on the solar panels. These sensors constantly monitor the thermal conditions and the presence of smoke in the vicinity of the panels.

When a fire is detected, the system is activated and starts the fire suppression process. It uses an extinguishing agent specific to solar panel fires, which is released directly on the affected panels.

The extinguishing agent used draws on the fire network. These agents are designed to quickly cool the panels and suppress the fire, minimizing damage to the panels and reducing the risk of re-ignition.

Our system can also be integrated with a remote monitoring and control system, allowing the proper authorities to be notified of the fire and to respond promptly.
