Fireproofing Measures for Solar

How Important Are Fireproofing Measures for Solar Panels?

Renewable energy workers face constant safety and compliance criteria updates as technology revolutionizes and regulatory agencies keep up with novel research. Solar panels need fireproofing measures just as much as buildings, so the sector must prioritize making commercial and residential solar user-friendly and safe. What fireproofing tactics do installers need to know about panels, especially when practicing safety?

What Makes Solar Panels Fire-Resistant?

Solar panels are not inherently fireproof, but many ingredients are not typically flammable, like glass and silicon. The flammable parts include plastic and polymers, but coatings exist to blanket modules for increased resistance. Extenuating circumstances like lightning and leaking chemicals — such as phosphorus and cadmium telluride in thin-film panels — could cause the panel to ignite. These chances are slim but essential to defend against.

Fireproofing also includes mechanisms. For example, operators must be able to have fine control over inverters to cut power during emergencies. Parts like the junction box have special connector types designed to decrease fire risks and susceptibility to arcing.

Another problem is rooftop insulation interacts with wiring. If it is made from a combustible material, putting it around hot wires will cause fires. However, designing thick, temperate casings helps. Fireproofing solar panels is essential because it keeps anything they are connected to just as safe.

What Fire Risks Are Associated With Solar Work?

Energy and electrical workers know countless catalysts could urge a spark or fire. This ranges from manufacturing defects to user error and it is crucial to acknowledge fireproofing measures from each perspective. Industry professionals must educate clients on existing fireproofing measures, insurance options and maintenance for the system’s longevity.

Conveying this information based on what kind of solar PV system it is — grid-dependent, isolated battery storage or backup — is required for renewable energy’s reputation. These notable installation or production oversights could cause fires:

  • Poor thermal management in inverters, transformers and other components
  • Noncompliant installation and risk assessments
  • Defects catalyzing electric arcs

Solar panels are constantly exposed to stressful environmental conditions such as intense heat, force from severe weather and debris buildup. Their components must be sturdy against these influences by having proper sealants, robust wiring and high-quality raw materials. This includes the inverters, cables and isolators with equal gravity. Additionally, adequate inspection protocols incorporate checks for production and installation quality.

What Measures Should the Industry Look To?

The IREC Model Interconnection Procedures from the Interstate Renewable Energy Council and the Solar Training and Education for Professionals program from the Solar Energy Technologies Office are examples of frameworks and actions meant to boost fire safety. The STEP program has readied over 10,000 firefighters and officials with the tools to isolate flames and spread this education to 90,000 more participants.

All installers must conduct fire risk assessments and damage recovery if fire strikes to prevent further incidents. Ensuring strict adherence to frameworks and continued funding for training programs will be the foundations for success. Here are some of the other notable organizations and structures professionals should become familiar with to learn more about fireproofing and safety in solar:

  • North American Board of Certified Energy Practitioners for certification in solar tech
  • National Solar Licensing Database for licensing requirements for prospective installers
  • National Electrical Code for solar safety standards for fires and other hazards
  • Underwriters Laboratories for panel testing
  • International Building Codes for construction and design guidance
  • International Fire Codes for best practices

How Can Renewable Energy Installers Stay Safe?

If a fire begins, shutting down the PV system and contacting relevant authorities are the most important steps from a consumer and professional perspective. The controls should have clear labeling to distinguish them from other power generators in the home.

Production and installation experts and homeowners must keep access to solar systems unobstructed so responders may handle them quickly and efficiently. Only trained professionals should tackle the situation with adequate fire suppression.

Another way solar workers remain safe is by making sure they apply fireproofing and safety measures to connected power systems. Buildings may opt for battery backup infrastructure to store excess power and employ it in an emergency. These generators should maintain just as rigid fire safety precautions as the PV system.

The Perfect Amount of Heat

Solar panels are meant to get hot as they manipulate the sun’s light and warmth into clean power. However, installers, manufacturers and panel owners must participate in their respective fire safety roles. It is essential to recognize no technology is perfect, and improving fireproofing standards and practices in the solar sector will inspire other renewable industries.
