One of the biggest risks posed by pigeons is damage to wiring. Birds often peck or chew near electrical cables, which can result in faults, short circuits, or even fire hazards. Repairs are not only costly but can also void warranties if unauthorised work is carried out.
Pigeon activity under your panels also reduces system efficiency. Droppings and nesting materials block airflow, creating hotspots that reduce output and overheat components. Even a small build-up of debris can lead to noticeable performance losses. In addition, droppings can fall across panel surfaces and cut down the amount of sunlight your system can absorb.
The problem doesn’t stop with efficiency. Bird droppings are highly acidic, and over time they corrode surfaces, leading to premature wear and staining. They also carry bacteria and parasites that can pose health risks, especially if they accumulate on walkways, patios, or outdoor furniture beneath the panels. And of course, pigeons bring noise, feathers, and mess, all of which can be a major nuisance for homeowners.
The most reliable way to keep pigeons away is to install a physical barrier around your panels. Professional installers use a specially designed steel mesh that clips securely to the edges of the panels without drilling or damaging them. This mesh blocks pigeons from accessing the underside while still allowing air to circulate freely, so your system remains well ventilated. Unlike cheaper alternatives such as chicken wire, coated steel mesh is durable, rust-resistant, and designed to last for many years.
Protection doesn’t stop once the mesh or spikes are installed. At Rooftop Renewables, we offer ongoing maintenance and support to keep your panels in top condition. Our team carries out regular check-ups and cleaning, ensuring that the barriers remain secure, the system continues to operate efficiently, and pigeons are kept out for good. With professional maintenance, you can be confident that your solar panels will stay safe, clean, and fully functional year after year.
Some homeowners also choose to install bird spikes along roof ridges, chimneys, or other popular perching spots. While spikes won’t stop pigeons from trying to nest under panels, they can reduce the number of birds roosting nearby and make the roof a less attractive environment overall. Visual deterrents such as reflective tape or decoy owls are occasionally used too, but these tend to have limited long-term effectiveness as pigeons quickly adapt to them. They are best used as supplementary measures rather than primary protection.
At Rooftop Renewables, we take a comprehensive and humane approach to pigeon proofing. Our mesh systems are designed specifically for solar arrays, using non-corrosive, long-lasting materials that won’t damage your roof or panels. We ensure every edge is securely sealed, preventing pigeons from squeezing through even the smallest gap. Importantly, our solutions are discreet, meaning your panels remain visually appealing while being fully protected.
We also recommend carrying out a clean before installation. This removes any nesting debris or droppings that might otherwise attract birds back to the area. Once proofed, your system should remain free of pigeons, though we do suggest occasional inspections to make sure everything stays intact over the years.
The benefits of pigeon proofing go beyond avoiding repair costs. By keeping your panels clear of droppings and debris, you protect their efficiency and lifespan. A well-installed bird-proofing solution can add 10+ years to your system’s lifespan. Panels that remain unobstructed and well-ventilated generate more electricity, ensuring you get the best return on your investment. It also keeps your roof quieter, cleaner, and more hygienic, which is better for both property value and day-to-day enjoyment of your home.
Pigeons may seem like a minor inconvenience, but for solar panel owners they can cause real and lasting harm. From chewed wiring to reduced efficiency and unsightly mess, the problems only grow if left unchecked. Installing pigeon proofing early is the smartest way to safeguard your system, maintain peak performance, and avoid unexpected repair bills.
