Solar panels are growing in popularity, but the curiosity about how they function and their safety is too—from the impact on the structural integrity of your roof to the electromagnetic fields generated. We will explore the biggest safety considerations and concerns associated with installing solar panels to ensure adding rooftop solar to your home brings only benefits.

Solar Panels and Roof Protection

As you’re considering making the switch to solar, you may wonder, “Is it safe to have solar panels on my roof?” The answer here is almost always yes; however, the following safety considerations should be reviewed to determine the condition of your roof before moving forward.

1. Do your research before hiring a solar installation company.

Proper rooftop solar installation by certified photovoltaic (PV) specialists is critical to mitigating risks associated with structural issues and electrical hazards.

Improper installation of solar panels can lead to roof leaks, moisture and heat damage, and sometimes weight damage. Here at Blue Raven Solar, we follow all industry best practices and safety guidelines. Our focus is ensuring our installations are carried out with proper design, planning, and care to minimize potential risks.

2. Use high-quality equipment and technology.

Check with your solar panel installation partner to see what equipment they intend on installing, ensuring it meets the mandated safety requirements and is covered by warranties and guarantees. Look for certification from organizations such as the International Electrotechnical Commission (IEC) or Underwriters Laboratories. 

At Blue Raven Solar, our customers receive the best technology—from the solar panels on your roof to home storage solutions. We use tier-1, monocrystalline, black PV panels and reliable microinverters, all backed by a 25-year manufacturer warranty, a service warranty, and a two-year production guarantee.

3. Condition and Age of Your Roof.

Before installation of a solar panel system, it is essential to assess the structural integrity of your roof. Does it show significant wear and tear, such as leaks, cracks, or missing tiles? 

It is also important to check the load-carrying capacity of your roof, framing, and decking. Doing so will determine whether your roof can support the additional weight of a solar panel system, which weighs 2-4 pounds per square foot. Occasionally, a roof may require replacement or additional reinforcement to ensure solar panels are installed safely and securely.

What are the Health Risks of Going Solar?

When installed properly, following all safety measures, and adhering to industry standards, there are no health risks associated with installing or maintaining solar panels on your roof. 

The materials used in solar panels, such as silicon, cadmium, and copper, are not inherently harmful when the panels are in use. While solar panels generate low levels of electromagnetic fields during their operation, there is no conclusive evidence they cause harm to humans.

Are Solar Panels Safe During Severe Weather?

Solar panels are designed with various elements helping protect them against environmental factors like moisture and UV radiation to withstand extreme weather events, such as hailstorms, wind and flying debris, and heavy snow loads.

Each PV panel has a layer of tempered glass to protect it against extreme weather. Most monocrystalline panels are also completely encased in a steel or aluminum frame, providing structural support and an additional layer of protection.

Can Solar Panels Cause Fires?

Solar panels generate and transmit electrical energy, making electrical safety a top priority and concern. The installation process includes intricate electrical work, such as connecting panels to inverters and linking them to the utility grid. Certified professionals with expertise in electrical systems must assist and approve the installation.

As with anything relating to an electrical system, there is a fire risk if installed, managed, and maintained improperly. When solar panels are installed correctly, there should be no significant risk to your home. Fires from solar panels are rare, but the National Electrical Code established safety standards to help address and mitigate the concern. One requirement is all solar panel systems have a rapid shutdown feature. This is used as a quick way to de-energize your solar panels and allow first responders to act quickly in the event of a fire.  

To further support first responders in an emergency, your home should have clear labeling indicating which power lines are connected to your solar panel system. Your solar installer should also factor in fire access pathways, or fire setbacks, in the design of your system, as solar panels cannot be placed on any area of the roof below an emergency escape or rescue opening. The specific requirements vary by your location, so it’s important to ensure you choose a solar installation company knowledgeable of the requirements in your specific area.

Extend the Life of Your Roof

Solar panels can offer a small layer of protection to your roof, extending its life. By shielding it from sunlight, weather, and debris that otherwise would come in contact with it, your roof is protected from everyday wear and tear. 

Solar panels also offer a slight cooling effect for your home by directly absorbing sunlight. The gap between the underside of a solar panel and your roof also allows for airflow and circulation, which keeps the roof cooler by as much as 5 degrees.

It’s recommended to schedule regular maintenance of your solar panels at least once every two years to ensure optimal performance of your roof and solar panels. Inspections and maintenance can happen sooner or more frequently if you’ve experienced severe weather in your area, such as heavy snows or hailstorms, strong windstorms, earthquakes, or fires.
