Solar panels are an incredible investment – cutting electricity costs, boosting property value, and supporting a greener planet. But if pests like birds, squirrels, and rodents take up residence beneath your panels, they can cause severe damage to wiring, mounting structures, and even the panels themselves. Pest infestations don’t just threaten your system’s performance, they can also shorten its lifespan and lead to expensive repairs.
Pest exclusion is the proactive way to protect your solar setup before problems escalate. Instead of waiting for damage to occur, you can take preventive measures that keep unwanted critters out for good. In this blog, we’ll explore the most common solar panel pest threats, why exclusion matters, and the proven strategies that actually work.
When solar panels are installed, the space between the panel and the roof creates a shaded, warm, and sheltered gap, perfect for nesting. Here are the most frequent culprits:
1. Birds nesting under panels
Pigeons, sparrows, and other birds love the safe environment beneath panels. Unfortunately, their droppings are highly acidic and can stain panels or corrode metal parts and roofing. Their nesting materials can also block water drainage, leading to moisture buildup and mold growth on your roof.
2. Squirrels chewing on wiring
Squirrels often seek shelter under panels and use electrical wires for nesting materials. Their constant chewing can strip insulation from wires, increasing the risk of short circuits, power loss, or even electrical fires.
3. Rodents creating nests
Mice and rats are small enough to squeeze into tight spaces, and once inside, they can quickly multiply. Their droppings can cause sanitation issues, and like squirrels, they can damage wiring and insulation.
4. Insect infestations
While less common, wasps and bees sometimes build hives near or under panels. This not only poses a safety hazard for maintenance crews but can also block airflow around panels, affecting cooling and efficiency.
5. Reduced Energy Output
Pest activity can shade or physically damage the panels, directly impacting their ability to capture sunlight efficiently and lowering your overall energy savings.
Pest exclusion isn’t just about keeping your system clean, it’s about ensuring peak performance and avoiding costly problems down the road. By implementing a pest exclusion plan early, you’re making a long-term investment in your solar system’s efficiency and durability.
The best pest exclusion plans are proactive, durable, and tailored to your installation. Here’s what works:
1. Install protective mesh guards
A high-quality stainless steel or coated wire mesh barrier is the gold standard for keeping pests out. Installed around the perimeter of your solar array, it blocks entry points without restricting airflow. Mesh guards are corrosion-resistant and blend in with the panel frame for a discreet look.
2. Remove any pigeon signs
If pigeons frequently perch on your roof, it’s likely they’ve already marked your home with their scent, signalling your home as a safe space for them. It’s imperative that their scent is completely removed from your roof so they do not return.
3. Keep your roof and gutters clean
A clean environment is less attractive to pests. Regularly removing leaves, sticks, and debris from your roof and gutters eliminates potential nesting materials and hiding spots.
4. Seal roof entry points
Pests often find other ways into your attic or home, which can draw them toward your panels. Inspect and seal gaps in your roof, vents, and eaves to cut off these access routes.
5. Schedule professional inspections
Solar panel pest issues often go unnoticed until damage is severe. By scheduling annual inspections with a pest exclusion expert, you can catch early signs of activity and take action before it impacts your energy production.
While DIY exclusion kits are available, they often fall short in durability and long-term effectiveness. Professional exclusion services:
With a professional approach, you’re not just reacting to pest problems, you’re preventing them entirely.
Investing in pest exclusion delivers measurable returns over time. Benefits include:
Over the lifespan of your solar investment, the cost of exclusion is minimal compared to the potential savings from avoiding pest-related damage.
Your solar panels work hard every day to power your home but without pest exclusion, they’re vulnerable to hidden threats. Birds, squirrels, rodents, and insects can quietly cause thousands of dollars in damage and reduce your system’s efficiency. By taking proactive steps like installing mesh guards, keeping your roof clean, and working with experienced professionals, you can protect your panels, maximize energy production, and enjoy the full benefits of your investment for years to come.
