Novel Insight |
Risk Factors |
| 1 |
Understand the basics of solar panel systems |
A photovoltaic (PV) system converts sunlight into direct current (DC) electricity, which is then converted into alternating current (AC) electricity by an inverter for use in homes and businesses. |
Lack of understanding of the basic components of a solar panel system can lead to improper installation and maintenance, increasing the risk of arc flash hazards. |
| 2 |
Identify potential arc flash hazards |
An arc flash is a dangerous electrical explosion that can occur when an electric current passes through the air between two conductors. Arc flash hazards can occur during installation, maintenance, and repair of solar panel systems. |
Failure to identify potential arc flash hazards can lead to serious injury or death. |
| 3 |
Implement safety measures |
Ground fault protection, overcurrent protection, and short circuit protection are essential safety measures that must be implemented to prevent arc flash hazards. Personal protective equipment (PPE) such as arc-rated clothing, gloves, and face shields should also be worn. Lockout/tagout procedures should be followed to ensure that the system is de-energized before any work is performed. |
Failure to implement safety measures can result in serious injury or death. |
| 4 |
Conduct a flash hazard analysis |
A flash hazard analysis is a comprehensive study of the electrical system to determine the potential for arc flash hazards. This analysis should be conducted by a qualified professional and should include an assessment of the system’s electrical components, the likelihood of an arc flash occurring, and the potential severity of the hazard. |
Failure to conduct a flash hazard analysis can result in serious injury or death. |

Common Mistakes And Misconceptions
| Mistake/Misconception |
Correct Viewpoint |
| Solar panels do not catch fire. |
While solar panels themselves may not catch fire, they can still pose a risk of fire if installed or maintained improperly. Faulty wiring, improper installation, and debris accumulation on the panels can all increase the risk of a panel catching fire. |
| Only old or damaged solar panels are at risk for fires. |
Even new and properly installed solar panels can pose a fire risk if there is an issue with the electrical system or other components in the system. Regular maintenance and inspections are important to ensure that any potential issues are caught early before they become a hazard. |
| There is no need to worry about fires from solar panels because they don’t produce as much heat as traditional power sources like fossil fuels. |
While it’s true that solar energy doesn’t produce as much heat during normal operation compared to fossil fuels, it’s important to remember that any electrical system has the potential for overheating and sparking a fire if something goes wrong. Proper safety measures should always be taken regardless of the type of energy source being used. |
| Firefighters cannot safely extinguish fires involving solar panels. |
Firefighters have been trained on how to handle situations involving rooftop solar systems and have specialized equipment designed specifically for these types of incidents such as insulated gloves, rubber soled boots etc., which allows them to safely work around live wires while putting out flames. |
| Solar panel manufacturers provide enough information regarding safety precautions when installing their products. |
Although most manufacturers provide some basic guidelines for safe installation practices along with their product manuals but it’s also recommended that you consult with licensed professionals who specialize in designing & installing photovoltaic (PV) systems since every home/building has unique requirements based on its location & structure. |
