For the most part, solar panels are very safe, and it’s quite rare for them to catch fire. However, it’s not completely impossible. So, what are the potential causes of solar panels catching fire?
Solar panels that have not been installed properly
One of the biggest risks comes from improper installation. Many people try to save money by going with a cheaper installer, but this can backfire. Inexperienced or careless installers might set up a faulty wiring system, which could lead to overheating. When too much heat is generated, it can eventually ignite the materials around the panels, creating a fire hazard. Choosing a reputable company with a solid track record is key to avoiding this.
Corrosion
While solar panels are designed to handle harsh weather, water can sometimes sneak into the electrical components, especially if the installation wasn’t done perfectly. Water intrusion can cause corrosion, which could lead to overheating and, in rare cases, a fire. If you live in an area with heavy rainfall, it’s a smart idea to have your solar panels inspected regularly to check for any signs of water damage.
Cheap or defective components
Even the highest-quality solar panels can sometimes malfunction, but the risk is much higher if your system uses cheap or defective components. Many budget installers keep their costs low by using subpar parts, which increases the likelihood of future issues. While it might seem like you’re saving money upfront, cheap materials can lead to expensive problems down the road. This is why regular annual checkups are recommended to catch potential issues early on and ensure everything is working safely and efficiently.
To avoid your solar panels catching on fire, make sure you do the following:
1. Choose a reputable solar installer
One of the most important decisions you’ll make is selecting the right installer for your solar panels. Do thorough research on any company you’re considering. Look them up online, read customer reviews, and see what others are saying about their services. If an installer is significantly cheaper than their competitors, that’s often a red flag. Cheaper pricing might indicate they’re cutting corners on labour, materials, or experience—any of which could lead to a faulty system. It’s worth investing in a reputable company with a solid track record for safety and reliability, rather than risking future problems.
2. Use high-quality products
The quality of the components used in your solar panel system plays a role in preventing potential hazards. Make sure that your panels, inverters, and other related equipment come from established manufacturers with a strong history of producing safe and reliable products. Cheaper or lower-grade parts are more likely to fail, and in the worst cases, malfunctioning components can lead to overheating or even fire. Spending a little more upfront for high-quality products will give you peace of mind and help avoid costly issues down the road.
3. Perform regular maintenance checks
While keeping your solar panels clean is important, regular professional maintenance is just as critical to ensure your system is operating safely. Dirt and debris can affect efficiency, but unseen electrical issues can pose far greater risks. At least once a year, hire a qualified professional to thoroughly inspect your solar panels and the entire system. They can check for any signs of wear, corrosion, or faulty wiring, and catch small issues before they turn into bigger problems. Proper maintenance helps extend the life of your system and ensures it continues to perform safely and efficiently.
