You made a smart decision getting solar. You’re saving money and supporting clean energy. Your solar array is a wonderful investment for your home. But there’s one sneaky threat most homeowners overlook. That danger comes from local wildlife living right in your own neighborhood.
Animals love the warm, sheltered space under your panels. Unfortunately, this prime real estate can spell disaster for your system. Did you know that animal interference is a leading cause of solar panel damage? One report found that up to 46% to 89% of efficiency loss in solar panels is due to bird droppings.
We often hear from frustrated homeowners who learned this lesson the hard way. They wonder if critter protection is truly necessary or just an upsell. It is essential. Critter guards are the proven way to keep your solar investment safe. If you already suspect you have a problem, you can learn about our effective methods right here: Solar Panel Critter Solutions.

Critters Are One of the Biggest Silent Threats to Your Solar System
Critters like pigeons, squirrels, and raccoons find their way under your solar panels easily. Panels are installed a few inches above your roof to allow for cooling airflow. This gap creates a perfect, secure, and warm space. Squirrels jump from nearby trees or run along the gutter. Pigeons simply walk or fly in. Raccoons, though larger, can climb the array supports to settle in for a long stay.
Over time, this quiet activity causes extensive hidden damage. You won’t see the problems from the ground. But they are still happening. Critters chew on essential wires. They build nests out of flammable materials. Their mess traps heat, which wears down the system faster than it should. This damage slowly reduces your energy production and can create dangerous safety risks for your home.

The specific types of damage caused by these pests often include:
- Chewed wires
- Panel hot spots
- Nest fire hazards
- Roof leaks
- Drop in power output
5 Top Myths About Solar Panel Critter Problems — Debunked
A lot of misinformation exists about protecting your solar panels from local wildlife. It’s easy to believe these myths and put your valuable system at unnecessary risk. Here, we set the record straight on the most common misunderstandings we hear. When you know the truth, then you can take the first step toward smart protection.
Myth #1: Critters Don’t Affect Solar Panels
This is the most dangerous myth of all. People often think the panels themselves are too durable for an animal to harm. While the glass surface is tough, the wiring underneath is completely exposed. Critters cause damage every day across the country. This leads to expensive failures.
- Squirrels use the wires to chew and sharpen their constantly growing teeth.
- Highly acidic pigeon droppings can corrode the aluminum frames.
- Nests trap heat, causing the panels to overheat and perform poorly.

Myth #2: Critter Guards Are Optional
Many homeowners see critter guards as a simple, unnecessary add-on. They think they can wait until a problem starts before installing protection. By the time you notice an issue, significant, costly damage has already been done. Critter guards are proactive protection for your investment.

- Waiting for visible signs means you are already dealing with expensive repair bills.
- The guards act as a physical fence, stopping the animals before they can enter the array.
- Prevention is truly worth the upfront investment in solar protection.
Myth #3: Noise or Debris Means Nothing Serious
Do you hear scratching, chirping, or thumping from your roof? That is a serious warning sign. Do you see sticks, leaves, or droppings around your panels? Then, you have an active problem. If you ignore these clear signs, it can be a huge mistake. It will cost you money later.
- A little noise is proof of an active infestation or nesting under the array.
- Debris is what birds use to build nests. These nests create a huge fire hazard.
- Every day you wait, the critter colony grows. Then, the system damage gets worse.
Myth #4: My Warranty Will Cover Critter Damage
This is a very costly misconception. The vast majority of homeowner insurance policies and solar manufacturer warranties specifically exclude damage caused by pests and vermin. Check your documents carefully. If a squirrel chews a wire and causes a short, the repair bill comes straight to you.
- Solar warranties cover manufacturing defects, not animal destruction.
- The costs for wire replacement and panel cleaning can quickly reach thousands of dollars.
- Many warranties are completely voided if they find animal nests or droppings that caused a failure.
Myth #5: Any Handyman Can Install Critter Guards
Installing critter guards correctly requires specialized experience and knowledge. It’s not just a matter of wrapping a simple fence around the array. Improper installation can damage your roof shingles or void the solar panel manufacturer’s warranty immediately.
- You must use non-penetrating clips to attach the mesh to the panel frame without drilling.
- A general handyman may not understand proper solar wiring or roof safety procedures.
- Professional installers ensure a snug, gap-free seal that truly keeps animals out.
What Happens If You Ignore Critter Problems?
When you leave your solar system unprotected, you are asking for trouble. The consequences are more severe than simply losing a little energy. You expose your home to several expensive and dangerous outcomes. It’s an unacceptable risk to take with such a significant home investment.
- Fire risk
- Warranty voiding
- Loss of power output
- Roof & insulation damage
- Health hazards from droppings

Critter solutions are much more than just a repair bill avoidance tactic. They are a necessary insurance policy for your entire solar investment.
