Solar panels have revolutionized how we harness energy. They offer a sustainable and eco-friendly alternative to traditional power sources. However, like any other investment, they require care and protection. At Solar Me, we've noticed that one of the growing concerns among NJ homeowners is the damage caused by pests and other rodents to their solar installations. This article aims to shed light on this issue and provide solutions to ensure that your solar panels are both long-lasting and efficient.
Common Pests that Damage Solar Panels
Solar panels, with their warmth and sheltered spaces, can inadvertently become a haven for various pests. Understanding these pests is the first step in preventing potential damage.
Birds, especially pigeons, are drawn to the warmth of solar panels. They often build nests beneath the panels or on the clay tile roofs which can lead to potential damage and debris accumulation. For NJ homeowners, this can be particularly frustrating during migration seasons when bird activity is at its peak.
Rodents such as squirrels and rats aren't just a nuisance; they can pose a significant threat to the wiring of solar installations. Their instinct to gnaw can lead to exposed wires that can compromise both the safety and the functionality of the system.
While not as common, larger mammals like raccoons can also be problematic. Their weight and activity can potentially damage the solar arrays. Plus, their tendency to scratch or burrow can lead to structural issues, especially on rooftops.
Primary Damages Caused by Pests
Pests can cause a range of damages, some of which can have immediate and long-term implications for your solar system.
Unfortunately, the insulation around solar panel wiring is a prime target for rodents. Exposed wires not only pose a risk of system malfunction but can also be a fire hazard, especially if the wires come into contact with flammable materials.
When animals nest under solar panels, they often bring organic materials. These materials can combine with moisture and lead to roof rot. This compromises the structural integrity of NJ homes.
Consistent airflow is crucial for the efficiency of solar panels. Any obstruction, like nests, can lead to uneven temperatures across the panel and create "hot spots." These spots can reduce the panel's efficiency and increase the risk of overheating.
Secondary Damages and Risks
While primary damages from pests can be immediately noticeable, secondary damages often lurk beneath the surface and manifest over time. This can potentially lead to more severe consequences. For example, these damages can affect the efficiency and lifespan of your solar installations and pose risks to the safety and well-being of NJ homeowners.
Water Damage and Mold
Water damage is a silent destroyer. When squirrels, raccoons, and other rodents compromise the roofing or the structure around solar panels, it can lead to water seepage in the affected area. Over time, this moisture can weaken the structural integrity of homes which is expensive to repair. Additionally, trapped moisture can create the perfect breeding grounds for mold growth. Mold damages structures and can also pose serious health risks such as respiratory issues and allergic reactions.
While solar panels themselves are designed to be safe, pest activity can cause compromised wiring and pose a fire risk. Chewed or exposed wires can create electrical shorts, especially when they come into contact with flammable materials like dry nests. For NJ homeowners, this is a significant concern, especially during the dry seasons when the risk of fires is higher.
Electrocution is a severe risk associated with damaged solar installations. Exposed wires, especially during wet conditions, can become live hazards. This is particularly concerning in areas with frequent rainfall or for homeowners who might be accessing solar installations for maintenance or checks.
Structural Damage to Solar Arrays
Pests, especially larger mammals, can cause structural damage to the mounting systems of solar panels. Over time, this can result in the panels becoming loose or even detaching, especially during strong winds or storms.
Decreased Property Value
Damaged solar installations can lead to a decrease in property value. Prospective buyers might be hesitant about homes with compromised solar systems which can lead to challenges during the sales process.
Increased Maintenance Costs
Secondary damages often lead to increased maintenance costs. All of the regular checks, repairs, and replacements can add up and make the solar system more expensive to maintain in the long run.
Preventative Measures and Solutions for Solar Installations
Ensuring the longevity and efficiency of solar installations goes beyond the initial setup. NJ homeowners can take proactive measures and solutions to protect their investments against potential pest damage. By understanding the various preventative measures available, you'll be able to make informed decisions that protect your solar panels and enhance their overall efficiency.
Physical Protective Barriers
Physical barriers serve as the first line of defense against pests. These types of solar panel protection are incredibly effective but require significant investment and greatly increase solar array installation costs.
- Mesh Guards: These are designed to prevent pests, especially birds and rodents, from accessing the underside of solar panels. They're made from durable materials and are resistant to weather conditions. They can last for years without needing replacement.
- Critter Guard: These products are specialized barriers that deter larger mammals like raccoons. They're designed to withstand the weight and activity of these animals.
- Protective Skirts: These are installed around the perimeter of solar installations to prevent pests from climbing onto the panels from the ground or roof edges.
Routine inspections play a crucial role in early detection and intervention.
- Professional Checks & Diagnostics: Engaging professionals to conduct checks ensures that any signs of pest activity or damage are detected early. Our experts at Solar Me are trained to identify even minor issues that might escalate over time.
- Self-inspections: Homeowners can also conduct monthly visual checks to look for signs like droppings, nests, or chewed wires. Being proactive can help in early detection and intervention.
Companies specializing in solar panel protection offer tailored solutions to address specific pest-related concerns. These solutions can help offer maximum protection at a high cost, a price you might not be willing or able to pay. For more on-budget solutions, we encourage you to try using repellents that can be found in many home improvement stores like Home Depot.
