Quick Answer
Yes, consider fire regulations when installing solar panels, especially for ground-mounted systems, due to potential risks from electrical arcs and hot components.
Understanding Fire Regulations for Solar Panel Installations
When installing solar panels, it’s essential to consider fire regulations to ensure a safe and compliant setup. In the United States, the National Electric Code (NEC) Article 690 governs solar panel installations, and Section 690.11 requires that all electrical components be installed to prevent electrical arcs and overheating.
Assessing Fire Risks with Ground-Mounted Solar Panels
Ground-mounted solar panel systems can be more susceptible to fire risks due to their exposed and elevated installation. This is particularly true for systems with multiple arrays or those installed near vegetation. To mitigate these risks, installers should use fire-resistant materials for the racking system, and ensure that the array is installed at least 3 feet away from any combustible materials. Additionally, consider using a fire-resistant coating or treatment for the racking system, such as a UL 723 certified material.
Practical Steps for Compliant Installations
To ensure a compliant solar panel installation, conduct a thorough risk assessment before commencing work. Identify potential fire hazards, such as nearby vegetation, electrical wiring, or combustible materials. Use UL-listed components for electrical connections, and ensure that the array is designed and installed to prevent electrical arcs and overheating. Finally, consult with local authorities and follow relevant fire safety regulations to ensure a safe and compliant solar panel installation.
