Solar panels are a smart way to cut energy bills and lower your carbon footprint, but they’re not a set-it-and-forget-it type of solution. They need constant maintenance and observation to identify potential issues before they become huge problems.
One such issue that many homeowners do not expect is pests. The sleek panels provide a cozy hideout for birds, squirrels, rats, and even insects, offering the ideal space for hiding or nesting. Besides being a nuisance, these uninvited guests can damage wiring, block airflow, and leave droppings that reduce the panels’ efficiency. In some cases, pest activity can even pose fire risks or cause costly repairs.
In today’s guide, we’ll have a look at why pests are drawn to solar panels, the steps you can take on your own, and when it’s worth calling in the experts. Stay tuned!
Why Do Solar Panels Attract Pests?
Small animals and insects find shelter, warmth, and shade under your solar panels, so you should expect to find pigeons (and other small birds), rodents (squirrels and rats in particular), and insect nests (bees, wasps, or aquatic insects) under or on them.
If your panels are mounted on the roof, pay close attention to the gap between the panels and the roof. That’s the perfect narrow place that small animals seek when they want comfort and safety.
While you may think, “Hey, these guys are small, how much damage can they do?” the reality is quite bleak. Bird and insect nests can obstruct airflow, causing the panels to overheat and lose efficiency. Also, the acidic droppings of birds can corrode the equipment. Rodents do what they do best, which is chewing on wiring and pieces of equipment.
Meanwhile, aquatic insects, which are attracted to the polarized light reflected by the panels, can lay eggs on the surface.
Should I Call the Professionals?
While you can (and should) remove any inactive nests, debris, or droppings, pest removal is not that easy. Considering the delicate surface of solar panels, the situation becomes even more challenging.
So, if you’re facing a situation you can’t control, it’s best to call in the professionals. But which ones? Pest control or solar panel maintenance?
This depends on the situation. If your panels are being invaded by birds, rodents, or insects, start with pest control. You want to put a stop to the invaders that are actively damaging the panels.
A team of licensed pest removers, like the professionals at Anticimex Carolinas, will have the right tools and knowledge to manage infestations humanely while protecting your panels from further damage.
Once the main threat to the integrity of your solar panels has been removed, it’s time to call in a maintenance team. They will inspect the system, identify any problematic areas, and recommend repairs.
Both teams can recommend actions that help prevent this situation from happening again, such as:
- Barriers such as mesh or critter guards should be placed around the edges of panels to prevent birds, rodents, and squirrels from nesting underneath.
- Install deterrents, like reflective tape, bird spikes, and ultrasonic devices, to discourage pests from settling near your roof. Even simple solutions like pinwheels or motion-activated sprinklers can add extra protection.
- Regular maintenance: Keep panels clean, trim nearby trees or shrubs, and check for droppings or nests. Catching early signs of pest activity can save you from bigger repairs later.
In Summary
Pest-proofing is just as vital as cleaning for solar owners. By treating prevention as routine care, you ensure your panels stay efficient, safe, and ready to power your home for years ahead.
