How to Squirrel-Proof Solar Panels in NJ

New Jersey's lush landscapes and diverse wildlife make it a beautiful place to call home. However, the very elements that make the Garden State so appealing can also pose unique challenges for solar panel owners. Squirrels, in particular, are notorious for their persistence when it comes to infiltrating solar installations. Fortunately, there are steps you can take to squirrel-proof your solar panels and protect your investment in the heart of New Jersey.

1. Inspect Your Property

  • Begin by conducting a thorough inspection of your property. Identify nearby trees, branches, or structures that could provide easy access for squirrels to jump onto your solar panels.

2. Tree Trimming

  • Trim tree branches that overhang or come close to your solar panels. Squirrels often use these branches as launchpads to reach the panels.

3. Install Critter Guard

  • Consider installing Critter Guard, a highly effective solution designed to keep squirrels and other critters away from your solar panels. This protective barrier is specifically designed to fit around solar arrays, preventing access without harming the animals.

4. Secure Entry Points

  • Examine your roof and any potential entry points. Seal off openings and gaps where squirrels could gain access to the underside of your solar panels.

5. Scent Deterrents

  • Some homeowners find success using scent deterrents, such as predator urine or mothballs, near their solar panels to discourage squirrels from approaching.

6. Regular Maintenance

  • Stay vigilant with regular maintenance. Check for signs of squirrel activity, like chewed wires or nests, and take swift action to address any issues.

7. Professional Assistance

  • If squirrel activity becomes a persistent problem, consider seeking professional assistance from wildlife removal experts like "Conscious Critter Removal." They have the expertise to safely and humanely remove squirrels from your property.

By implementing these measures, you can greatly reduce the risk of squirrel-related damage to your solar panels in New Jersey.

Understanding Why Squirrels Go Under Solar Panels Before we delve into prevention methods, it's essential to understand why squirrels are drawn to the space beneath solar panels:

  • Shelter: Squirrels seek shelter under solar panels to escape harsh weather conditions, including extreme heat and cold.

  • Nesting: They often view the area as an ideal nesting site, where they can safely raise their young.

  • Protection: The underside of solar panels provides protection from predators, making it an attractive option for squirrels.

By implementing these measures, you can effectively keep squirrels from going under your solar panels and protect your solar investment. Let's explore effective ways to prevent squirrels from going under your solar panels:

1. Install Critter Guard: Consider installing Critter Guard. This specialized barrier is designed to fit seamlessly with solar panels, creating a physical barrier that prevents squirrels and other wildlife from accessing the area underneath

2. Regular Inspections: Conduct regular inspections to detect any squirrel activity or entry points beneath the panels. Inspect your solar panel installation for any openings or gaps that squirrels could exploit to gain entry beneath the panels. Seal these gaps with durable materials to deny access

3. Seal Entry Points: Seal any openings or gaps under the panels that squirrels could use for access.

4. Trim Overhanging Branches: Trim tree branches that may serve as a jumping point for squirrels onto your panels. If squirrels have already taken up residence beneath your solar panels, it may be necessary to trap and relocate them. Consult with wildlife removal professionals who can safely and humanely handle this process. Contact Conscious Critter Removal today for help trapping and removing animals from your solar panels.

5. Consider Scent Deterrents: Some homeowners use scent deterrents, like predator urine or mothballs, to deter squirrels from approaching the panels. Squirrels may be discouraged by strong-smelling fragrances like peppermint oil. Predator urine makes the squirrel think a predator is in the area, and that they should leave quickly.

By implementing these preventative measures, you can significantly reduce the risk of squirrels finding their way under your solar panels. Critter Guard, in particular, is a reliable solution to fortify your solar array against these determined intruders, ensuring that your clean energy investment remains secure and hassle-free.

Squirrels and Nests Under Solar Panels

Squirrels are not content with merely perching on top of your solar panels; they often take their invasion a step further by building nests beneath them. These nests can cause a range of problems, from damaging your solar system to creating safety hazards. Let's delve into the matter of squirrels and nests under solar panels.

Understanding Squirrel Nesting Behavior Squirrels are skilled nest builders and seek out secure and sheltered locations for their homes. Squirrels often view the space beneath solar panels as an ideal location to build their nests. The underside of solar panels provides several enticing qualities:
