Wildlife Threats to Solar Systems
Your solar panels create the perfect environment for wildlife. They provide shade, warmth, and protected spaces—making them attractive nesting spots. But when animals make themselves at home under your panels, they can cause serious damage that compromises your system’s performance and safety.
Common Wildlife Culprits in Western North Carolina
The Carolina climate and landscape create unique wildlife challenges for solar panel owners. The most common visitors to solar installations in our region include:
Birds: Birds see the protected space beneath panels as ideal nesting areas. Their nesting materials can block airflow, causing panels to overheat and reduce efficiency. Bird droppings also accumulate on panel surfaces, creating “hot spots” that diminish energy production and potentially lead to premature panel degradation.
Squirrels: Perhaps the most destructive visitors to solar installations, squirrels are drawn to the warm, sheltered environment under panels. Their tendency to chew on wires can lead to dangerous electrical problems, system failures, and fire hazards. A single squirrel can cause thousands of dollars in damage by chewing through the protective insulation on DC power cables.
Raccoons: With their dexterous paws, raccoons can manipulate and damage system components. They often create entryways for smaller animals by pushing aside poorly secured protective barriers.
Mice and Rats: These small rodents can squeeze through tiny openings and, like squirrels, have a tendency to gnaw on wiring. Their nests can also trap moisture against your roof, potentially causing structural damage beneath your solar installation.
Specific Damage Caused by Wildlife
The impact of wildlife on your solar investment goes beyond just the immediate damage:
Electrical System Damage: Chewed wiring isn’t just an inconvenience—it’s a safety hazard that can lead to system failures or even electrical fires. This type of damage typically isn’t covered under standard warranties and requires specialized repair.
Reduced Energy Production: When animals nest under panels, they block crucial airflow that helps maintain optimal operating temperatures. Solar panels become less efficient as temperatures rise, so nests can significantly reduce your energy production and financial returns.
Accelerated Wear and Tear: Wildlife activity can cause micro-movements in mounting hardware, potentially creating water entry points or structural stress that shortens system lifespan.
Roof Damage: When animals create homes under your solar panels, they can damage your roofing materials, potentially leading to leaks and requiring costly repairs that involve temporarily removing your solar installation.
Professional Critter Guard Solutions
Based on Sundance Power Systems’ three decades of experience in the Carolinas, we’ve developed and refined wildlife protection approaches specifically suited to our regional challenges.
Types of Protective Systems
Effective wildlife protection for solar panels must strike a balance between security and aesthetics while maintaining proper system ventilation and accessibility for maintenance.
Mesh Barrier Systems: These protective screens create a physical barrier that prevents animals from accessing the space beneath your panels while allowing for proper airflow. Quality mesh systems use galvanized steel or marine-grade stainless materials that withstand our Carolina weather conditions without rusting or degrading.
Integrated Panel Skirts: These specialized barriers follow the contour of your panels, creating a seamless look that maintains your system’s visual appeal. They’re particularly effective for installations visible from ground level or neighboring properties.
Custom Edge Protection: For unique installation configurations or homes with specific wildlife challenges, we design custom solutions that address particular entry points while maintaining system performance.
Material Considerations
The harsh UV exposure and varied weather conditions in Western North Carolina demand specific materials for lasting protection:
UV-Resistant Components: All protective elements must withstand years of sun exposure without degrading or becoming brittle.
Corrosion-Resistant Fasteners: The attachment methods are just as important as the barriers themselves. We use only stainless steel or specially coated fasteners that won’t corrode over time.
Non-Conductive Materials: Where components might contact electrical elements, we ensure all materials are non-conductive to maintain system safety.
Installation Process
Proper installation is critical to both the effectiveness and longevity of wildlife protection systems:
Assessment: Our NABCEP-certified technicians evaluate your specific system configuration, roof type, and local wildlife patterns to determine the most appropriate protection strategy.
Custom Fitting: Unlike one-size-fits-all approaches, we custom-fit barriers to your exact panel dimensions and mounting system, ensuring no vulnerable gaps remain.
Non-Invasive Attachment: Our installation methods preserve both your panel warranty and roof integrity while securely anchoring all protective elements.
System Inspection: After installation, we thoroughly inspect your entire solar array to verify all potential entry points are secured and system performance is unaffected.
DIY vs. Professional Installation
While the DIY approach might seem appealing from a cost perspective, wildlife protection for solar panels involves specific technical considerations that often require professional expertise.
The DIY Approach: Considerations and Limitations
Some homeowners consider installing critter guards themselves, but several factors should influence this decision:
Safety Concerns: Working on rooftops with electrical systems presents real safety hazards. Without proper training and equipment, there’s significant risk of personal injury or system damage.
