Pigeons love nesting under solar panels, and that can be a real nightmare for homeowners in Australia. They scratch up your panels, clog up airflow, and leave droppings that mess with efficiency. Over time, their nests can even lead to electrical damage and costly repairs.
On top of that, they bring noise, bacteria, and parasites—definitely not something you want hanging around your home.
Stopping pigeons before they take over is the best way to keep your solar system running smoothly.
Once they settle in, they’re stubborn and tough to remove. The right pigeon-proofing methods can keep them out for good, saving you from constant clean-ups and potential damage.
So, what’s the price of keeping them away? Costs depend on things like roof type, solar panel size, and the method used to block them. Some fixes are budget-friendly DIY jobs, while others need professional installation for long-term protection.
Here’s a look at what to expect when it comes to pricing, the best solutions, and what works best for Aussie homes.
Why Do Pigeons Nest Under Solar Panels?
Pigeons nest under solar panels because they offer everything a bird could want—warmth, shelter, and protection from predators.
Roof spaces with solar panels mimic the natural crevices pigeons use for nesting in cliffs and buildings. The moment one pigeon finds a spot, others follow, turning a few nests into a full-blown infestation.
Solar panels create the perfect microclimate. The space underneath stays dry during rain, shaded from the sun, and insulated against cold nights.
This makes it an ideal nesting site year-round. Pigeons don’t migrate, so once they find a good nesting location, they settle in permanently, raising multiple broods each year.
Another reason pigeons target solar panels is safety from predators. Birds of prey like hawks and eagles can’t easily reach them, and domestic pets don’t pose a threat up on the roof. With no natural deterrents, pigeons can breed undisturbed, leading to rapid population growth.
Roofs are also high-traffic areas for pigeons in urban environments. They naturally prefer ledges, beams, and roof gaps for roosting. If a home has a history of pigeon activity, solar panels become the next best option, providing better cover than traditional roof spaces.
Once a pigeon colony establishes itself under solar panels, they return year after year. Even if the birds are removed, the nesting materials and scent they leave behind attract new flocks looking for a home.
Common Problems Caused by Pigeons on Solar Panels
1. Droppings Reduce Panel Efficiency
Pigeon droppings are a real problem for solar panel performance. The acidity in their waste can corrode metal components, stain surfaces, and create a thick layer that blocks sunlight.
Less sunlight reaching the panels means reduced energy production, which leads to higher electricity costs.
Rain won’t always wash the mess away. Droppings harden over time, forming a crust that needs to be physically cleaned. The more often pigeons roost, the more buildup there is, and without regular maintenance, solar panels can lose a noticeable percentage of their efficiency.
2. Chewed Wiring and Fire Hazards
Pigeons aren’t just nesting under solar panels—they’re also pecking at wires and pulling them apart.
Loose or exposed wires aren’t something to ignore. Damaged cables can short-circuit, reduce the system’s output, or in the worst cases, spark a fire.
Solar panels rely on clean, intact wiring to function properly. When pigeons nest under them, they bring twigs, leaves, and other flammable debris. This combination of nesting material and electrical damage increases fire risks, especially during hot Australian summers.
Fixing chewed wiring isn’t cheap. A simple repair might cost a few hundred dollars, but if the damage is extensive, it could mean replacing multiple parts of the system. That’s an expensive problem that could have been avoided with proper pigeon-proofing.
3. Blocked Airflow Causes Overheating
Solar panels need proper airflow to stay cool and work efficiently. When pigeons build nests underneath, they block ventilation gaps, trapping heat.
Over time, this overheating can reduce the lifespan of the panels and lead to performance issues.
Heat buildup also makes the inverter work harder. The harder it works, the sooner it wears out, leading to premature repairs or replacements.
Homeowners dealing with pigeon infestations often notice sudden drops in efficiency, and blocked airflow is one of the biggest culprits.
4. Noise, Mess, and Health Risks
Pigeons are noisy. When they take over a roof, the constant cooing, scratching, and flapping can get frustrating, especially early in the morning. They don’t just stay quiet and nest—they’re always moving, always making noise, and always leaving behind a mess.
Their presence also brings health concerns. Pigeons carry bacteria, mites, and parasites that can spread through their droppings. Over time, dry droppings can turn to dust, which gets blown into the air and inhaled. This is a concern for people with asthma or respiratory issues.
If a house collects rainwater, pigeon droppings can contaminate it. That means bacteria and disease in the water supply, which can lead to serious health risks for households using it for drinking, cooking, or washing.
The longer pigeons stay, the worse the problems become. The nests grow bigger, the damage adds up, and the mess spreads. Getting rid of them early is the best way to avoid expensive clean-ups and repairs.
How Does Pigeon Proofing Solar Panels Help?
Pigeon-proofing solar panels keeps birds out for good, preventing damage, mess, and ongoing maintenance headaches.
A proper barrier stops pigeons from nesting under the panels, protecting the wiring, airflow, and surface from droppings and debris.
Without pigeons roosting, solar panels stay cleaner, which means better efficiency and more power generation. Droppings won’t build up and block sunlight, so there’s no need for frequent cleaning. Wiring stays intact, reducing the risk of electrical faults or fire hazards.
Airflow also improves. With no nests blocking ventilation gaps, panels stay cool, preventing overheating that can shorten their lifespan. Plus, no more noise, feathers, or bad smells around the roof.
Beyond protecting the system, pigeon-proofing makes the home healthier by reducing bacteria, mites, and parasites that pigeons bring. It’s a long-term fix that saves money on repairs, cleaning, and lost energy, making it well worth the investment.
How Much Does It Cost to Pigeon-Proof Solar Panels in Australia?
Average Price Range
Pigeon-proofing solar panels in Australia can cost anywhere from (AUD) $300 to $2,000, depending on the method used and whether it’s a DIY job or a professional installation.
- Basic solutions: $300 – $600 (AUD)
- Professional installation with high-quality materials: $800 – $2,000 (AUD)
DIY kits are usually cheaper, but they require time, effort, and the right tools. Professionally installed solutions last longer and come with warranties, making them a more reliable option for homeowners who want a long-term fix.
Pricing Based on Property Type
The cost also depends on the size and accessibility of the roof. Single-storey homes are easier to work on, so they tend to be on the lower end of the pricing scale.
Double-storey homes require more labour and safety equipment, increasing the cost.
- Single-storey home: $300 – $1,200 (AUD)
- Double-storey home: $600 – $2,000 (AUD)
DIY vs. Professional Pigeon-Proofing
DIY solutions can be tempting for homeowners looking to save money. Mesh kits, spikes, and netting are all available online or at hardware stores, usually costing between $100 and $500.
The problem is that DIY solutions don’t always last. If the materials aren’t installed properly, pigeons can still find their way in.
Professional services cost more but provide higher-quality materials, expert installation, and warranties. Professionals also clean out any existing nests and ensure that pigeons won’t return.
For homeowners who want a hassle-free solution that lasts, professional pigeon-proofing is the better investment.
Ongoing Maintenance Costs
Once solar panels are pigeon-proofed, maintenance costs are minimal. Most professional installations last 10+ years without needing replacement.
However, in areas with heavy bird activity, occasional inspections might be needed to check for damage or wear. If cleaning is required, it can cost between $150 and $300, depending on the size of the system.
For homeowners dealing with pigeons year after year, pigeon-proofing is a cost-effective solution that prevents ongoing cleaning and repair expenses.
Factors That Affect the Cost of Pigeon-Proofing Solar Panels
1. Size of Solar Panel System
The bigger the solar panel system, the more materials and labour are needed to protect it. A small system might only need a few metres of mesh, while a larger setup requires more coverage, increasing the cost.
Installers also charge based on time and effort, so if there are multiple rows of panels, it takes longer to secure everything properly.
For homes with large rooftop solar arrays, costs can easily go over $1,500, especially if extra barriers are needed to keep birds from moving to different sections of the roof. Larger systems also mean more cleaning if pigeons have already nested.
2. Roof Type & Accessibility
The type of roof plays a big role in the cost of pigeon-proofing. Tile roofs need extra care because they’re more fragile, and installers have to work carefully to avoid cracking tiles. This slows down the process and may increase labour costs.
Steep or complex roof designs also add to the price. If installers need special equipment, like harnesses or scaffolding, costs go up.
Homes with multiple levels, awkward angles, or difficult access points take longer to work on, which means higher labour fees.
A simple, flat roof is much easier and cheaper to pigeon-proof compared to a steep or multi-sectioned one.
3. Level of Infestation
The more pigeons there are, the more work it takes to get rid of them. A few birds can be shooed away easily, but a full-blown infestation means nests, droppings, and built-up debris that all need to be cleared before installing any barriers.
Cleaning dried droppings and nesting materials adds to labour costs, especially if the mess has been there for a while.
Heavily infested areas may also need stronger deterrents, like reinforced mesh or additional sealing, which increases the price. In severe cases, professional bird removal might be needed before pigeon-proofing can even begin.
4. Type of Pigeon-Proofing Method Chosen
The method used to keep pigeons away affects the cost. Mesh barriers are the most effective and widely used option, costing between $300 and $1,500 depending on the system size. They block birds completely while allowing airflow, making them a long-term solution.
Bird spikes are cheaper, usually costing $100 to $500, but they don’t always work for solar panels since pigeons can still nest underneath. Netting can cover larger areas for around $200 to $1,000, but it needs maintenance.
Repellent gels are the cheapest, $50 to $300, but pigeons often get used to them, making them unreliable over time.
5. Professional vs. DIY Installation
DIY pigeon-proofing is cheaper upfront, but it comes with risks. Mesh kits, spikes, and netting are available for $100 to $500, and installing them yourself saves on labour costs.
However, without the right tools or experience, there’s a higher chance of gaps or weak spots where pigeons can sneak back in. Climbing onto a roof is also dangerous, especially on steep surfaces.
Hiring a professional costs more, usually between $800 and $2,000, but the job is done properly. Licensed installers use high-quality materials, ensure complete coverage, and often provide warranties. For a long-term solution, professional installation is the safer investment.
Best Pigeon-Proofing Solutions for Solar Panels in Australia
1. Solar Panel Mesh (Most Popular)
Solar panel mesh is one of the best ways to keep pigeons out. It’s a metal barrier that surrounds the panels, blocking birds from getting underneath while still allowing proper airflow. This method works well because it completely seals off nesting spots without damaging the panels.
Costs range from $300 to $1,500, depending on the size of the system and installation fees. Professionally installed mesh lasts for years and requires little maintenance. While DIY kits exist, they don’t always provide a secure fit. For the best results, it’s worth getting a professional to install it properly.
2. Bird Spikes
Bird spikes are a simple way to discourage pigeons from landing near solar panels. They are attached along the edges of the panels, making it uncomfortable for birds to perch or roost. Since pigeons prefer stable surfaces, spikes push them to find another resting spot.
This is one of the more affordable options, costing $100 to $500, depending on the length and material. They’re easy to install and work well as a deterrent for mild bird activity.
However, spikes don’t stop pigeons from nesting underneath panels, making them less effective for homes with a serious infestation.
3. Bird Netting
Bird netting is a practical way to block pigeons from accessing the roof and solar panels. It creates a physical barrier that prevents birds from landing or nesting in unwanted areas. This method is often used when multiple sections of the roof need protection.
Costs range from $200 to $1,000, making it a budget-friendly solution for larger areas. Netting is effective, but it needs to be checked regularly for damage.
Strong winds, debris, or persistent birds can weaken it over time. For long-term success, proper installation and occasional maintenance are necessary.
4. Ultrasonic Bird Repellers
Ultrasonic bird repellers use high-frequency sound waves that pigeons find irritating, encouraging them to leave the area. Since the sound is outside the human hearing range, it won’t be a disturbance to people.
Prices range from $100 to $400, making this one of the more affordable pigeon deterrents. There’s no need for physical barriers or installation, which makes setup easy.
However, effectiveness varies. Some pigeons get used to the noise, especially if they’ve already been nesting in the area.
For homes with a serious infestation, ultrasonic devices may work better when combined with other deterrents like mesh or spikes.
Key Takeaway
Pigeons and solar panels don’t mix. They leave a mess, damage wiring, and reduce efficiency, which ends up costing homeowners more in cleaning and repairs. Blocking them out early makes a huge difference, saving money and keeping the system running at its best.
There’s a fix for every budget. Mesh barriers are the most effective, while bird spikes, netting, and ultrasonic repellers offer cheaper alternatives.
Professional installation costs more upfront, but it lasts longer and comes with fewer headaches. DIY solutions can work, but gaps or weak spots often mean pigeons find their way back.
