How Do Solar Panels Work?

Before we can understand the potential for solar panels to catch on fire, we must know how they work. Photovoltaic cells, the solar system’s building blocks, turn sunlight into electricity. The cells are connected by wires and housed in a protective panel. Electrons are jarred loose when sunlight strikes the cells, generating an electrical flow.

Factors That Can Cause Solar Panels to Catch on Fire

Although solar panel fires are rare, some factors can increase the risk of a fire. These include:
  • Faulty installation:
The fire risk can increase if the solar panels are not installed correctly. This can occur if the wiring is damaged during installation or if the panels are installed too close to other objects that can cause damage.
  • Damage to the panels:
Severe weather, such as hail or wind, can damage solar panels. In addition, vandalism can also cause damage to the panels. If the panels are damaged, it can increase the fire risk.
  • Electrical issues:
Solar panels generate electricity, and if there are any issues with the electrical components, it can increase the risk of a fire. This can occur if the wiring is damaged or the panels are not properly grounded.
  • Improper maintenance:
Regular maintenance is essential to keep solar panels working. If the panels are not maintained, it can lead to damage or electrical issues, increasing the fire risk.
  • Damage to the panel itself
Water and debris can enter the panel if a solar panel gets damaged and develops cracks or holes. This could result in a short circuit and a fire.
  • Electrical surges
 Too much electricity, called an electrical surge, can make the current jump and create sparks. These sparks can cause a fire in a solar system. 
  • Lightning strikes
Lightning can harm solar panels because they are often placed on high places, like roofs. Lightning can send too much electricity through the panels and start a fire.
 Solar panels can overheat if exposed to direct sunlight for prolonged periods, particularly in hot weather. Overheating can cause damage to the panels and other components of the system, leading to a fire.
Improper installation
If solar panels are not installed right, they can be dangerous and start fires. Poorly insulated wiring can create sparks and cause fires.
To stay safe, ensure solar panels are installed correctly, check them often, and look out for anything unsafe. Always follow safety rules.

How to Reduce Solar Panel Fires

To install solar panels, you must think carefully and plan to ensure the system is safe, performs well, and saves money.

How Are Common Solar Panel Fires?

Solar panel fires are not very common. In 2019, only 24 solar panel fires were reported in the United States, according to the National Fire Protection Association. This is minimal compared to the country’s total number of solar panel installations. 

What Happens When Solar Panels Catch on Fire?

Solar panels catching on fire can be dangerous because they can create flames and smoke that spread and damage buildings. The fire can also melt or collapse the panels and surrounding materials due to intense heat.
Suppose a solar panel system is connected to the electrical grid. In that case, a fire can cause electric shocks and power outages nearby. Additionally, when solar panels burn, they can release toxic gases that harm health.
Regular maintenance and inspection of solar panels are essential to prevent fires. Following safety guidelines and protocols can also reduce the risk of injury or property damage in the event of a fire.

Can Solar Panel System Fires Be Put Out?

Yes, solar panel fires can be put out. However, it is essential to note that they can be difficult to extinguish. Because the panels are often installed on the roof, it can be difficult for firefighters to access them. In addition, the presence of water can create an electrical hazard, so special procedures must be followed.

What Should You Do If Your Solar Panels Catch on Fire?

If your solar panels catch fire, call the fire department immediately. Do not attempt to put out the fire yourself, as this can be dangerous and increase the risk of injury or further damage.
Turn off the electricity to your home or business to reduce the risk of electrical shock. Evacuate the building immediately and stay a safe distance away until the fire department arrives. If you have a fire extinguisher and know how to use it, you can try to put out the fire from a safe distance, but only if it’s safe and you’re trained
