Common Problems Caused by Pigeons Nesting Under Solar Panels

When pigeons make a home under your solar panels, they can cause a variety of issues, some of which may affect the efficiency and longevity of your solar system. Here are the most common problems:

1. Reduced Solar Panel Efficiency

One of the biggest issues with pigeons nesting under solar panels is the buildup of droppings and debris, which can block sunlight from reaching the panels. When pigeons nest, they create messes with their droppings and nesting materials such as twigs, leaves, and feathers. This accumulation can obstruct the panels, limiting the amount of sunlight they absorb and significantly reducing their energy output. Even a small amount of shading from debris can lead to a noticeable drop in the system's overall performance.

2. Damage to Solar Panels and Wiring

Pigeons nesting under solar panels may also damage the system itself. Their constant movement, pecking, and nesting activities can loosen or break delicate wiring. Pigeon droppings are highly acidic, and over time, they can corrode metal parts and even the surface of the panels. If left untreated, this damage could lead to costly repairs or replacements, diminishing the lifespan of your solar installation.

3. Noise Disturbance

Pigeons are not quiet guests. The constant cooing, scratching, and flapping can become a major nuisance, especially if the solar panels are installed close to living spaces like bedrooms or home offices. The noise can be particularly disruptive in the early morning or late evening when the birds are most active, creating an unpleasant environment for homeowners.

4. Fire Hazard

Pigeons use flammable materials like twigs, grass, and dried leaves to build their nests. If these nests accumulate near the electrical components of your solar panel system, there is a potential fire risk. Combined with the heat generated by the solar panels, these flammable materials can pose a serious safety hazard. Regular inspections and pigeon-proofing measures can help reduce this risk.

5. Aesthetic and Property Damage

Apart from the technical issues, pigeon droppings and nests can be unsightly, detracting from the appearance of your home. Pigeon mess can accumulate quickly, leaving stains on the roof, walls, and around the solar panels. In some cases, the weight of multiple nests and droppings can damage roof tiles or other parts of your roofing structure, leading to further costly repairs.

Effective Pigeon Deterrents for Solar Panels

If you’re dealing with pigeons nesting under your solar panels, implementing the right deterrents can help protect your system and keep these unwanted guests at bay. Here are some of the most effective pigeon deterrents for solar panels:

1. Pigeon Mesh or Netting

One of the most reliable ways to keep pigeons from nesting under your solar panels is by installing pigeon netting for solar panels. This mesh creates a physical barrier around the perimeter of the panels, preventing pigeons from accessing the space underneath. The mesh is typically made from durable materials like stainless steel or heavy-duty plastic, ensuring it can withstand various weather conditions.

By covering the gaps between the panels and the roof, pigeon netting effectively blocks entry points without interfering with the performance of your system. Professional installation ensures that the mesh fits securely and remains in place for the long term.

2. Bird Spikes

Another highly effective pigeon deterrent for solar panels is bird spikes. These spikes are mounted along the edges of the panels or on nearby surfaces where pigeons like to perch. Made of plastic or metal, bird spikes are a humane solution, as they simply make landing uncomfortable for pigeons without causing harm.

Bird spikes are relatively easy to install and are often used in conjunction with other pigeon protection methods to create a comprehensive deterrent system.

3. Solar Panel Skirts

Solar panel skirts, also known as solar skirts, are a discreet and aesthetic solution for preventing pigeons from getting under the panels. These skirts attach along the edge of the solar array, sealing the gap between the panels and the roof, making it impossible for birds to access the area underneath. Solar skirts not only provide excellent pigeon protection for solar panels, but they also enhance the overall appearance of your roof by giving it a more streamlined finish.

4. Decoy Predators

Introducing visual deterrents like decoy owls or hawks can discourage pigeons from settling near your solar panels. These decoys mimic natural predators, and when placed strategically around your roof, they help create an environment that pigeons perceive as unsafe. While decoys may not be a standalone solution, they work well in conjunction with other methods, such as bird spikes or netting, to enhance their effectiveness.

5. Ultrasonic Repellent Devices

Ultrasonic devices emit high-frequency sounds that are uncomfortable for pigeons and other birds but inaudible to humans. These devices can be placed near your solar panels to keep pigeons away without causing any harm. Ultrasonic repellents are a low-maintenance option that can be effective for deterring birds over large areas.

6. Reflective Deterrents

Pigeons are often disoriented by reflective surfaces. Hanging reflective tape, old CDs, or aluminium foil around your solar panels can create flashes of light that scare pigeons away. While reflective deterrents may not be as long-lasting as other methods, they are an affordable and easy-to-install option, especially if you need a temporary solution.

Cleaning Solar Panels of Pigeon Droppings and Mess

Pigeon droppings and nesting debris can significantly impact the performance of your solar panels. If left unchecked, the mess caused by pigeons not only reduces the efficiency of your solar system but can also lead to permanent damage. Regular cleaning is essential to maintain the output of your solar panels and ensure they last for many years. Here’s how to clean your solar panels safely and effectively.

Why is it Important to Clean Pigeon Droppings?

Pigeon droppings are more than just an aesthetic problem. They contain acidic compounds that can gradually wear down the surface of your solar panels, corrode wiring, and reduce their efficiency by blocking sunlight from reaching the cells. In addition, the debris from nests and feathers can accumulate under the panels, obstructing airflow and potentially causing overheating.

Addressing these issues promptly will help maintain your panels' functionality and prevent costly repairs.

Safety First: Precautions Before Cleaning

Before you start cleaning, it's crucial to follow some safety guidelines:

• Turn off your solar system: Always shut down your solar panels before cleaning to avoid the risk of electric shock.
• Use safety equipment: If you need to climb onto the roof, make sure you're using the appropriate safety gear, such as a harness or non-slip shoes, and work with someone to avoid accidents.
• Check local regulations: If you live in a multi-story building, you may need professional assistance to clean solar panels safely and legally.

Tools and Supplies for Cleaning

To effectively clean pigeon droppings and mess off your solar panels, you will need the following supplies:

• Soft-bristle brush or squeegee: Avoid hard brushes or abrasive sponges, which can scratch the surface of the panels.
• Non-abrasive soap or cleaner: Choose a mild detergent to remove grime without damaging the panel’s coating.
• Water: Using distilled water is ideal as it won’t leave mineral residue or streaks. A garden hose with a spray nozzle can work well to rinse off the dirt.
• Soft cloth or microfiber towel: For wiping and drying the panels to ensure a streak-free finish.

How to Clean Pigeon Droppings from Solar Panels

Now that you have your supplies ready, follow these steps to clean your solar panels of pigeon droppings and mess:

Step 1: Rinse the Panels

Start by rinsing the panels with water to remove any loose dirt or droppings. Use a garden hose with a gentle spray to avoid applying too much pressure, which could crack the glass or disturb the panel’s mounting.

Step 2: Apply Soap

Mix a small amount of non-abrasive soap in water. Apply the soapy solution to the affected areas with a soft-bristle brush or cloth, scrubbing lightly to loosen any tough droppings. Be gentle to avoid scratching the glass.

Step 3: Rinse and Wipe

Once you’ve removed the droppings, rinse the panels thoroughly with clean water to wash away the soap and remaining dirt. Use a squeegee or soft cloth to remove excess water and prevent streaks from forming.

Step 4: Dry and Inspect

Let the panels air dry or use a microfiber cloth for a spotless finish. After drying, inspect the panels to ensure all droppings and dirt are removed, especially from the corners and edges where buildup tends to accumulate.
