In the UK over one million properties feature rooftop solar panels. It is crucial to protect these systems from pigeons and other birds that may nest beneath them. The gap under solar panels offers shelter from weather and predators, making it an attractive spot for birds to roost and nest, which can cause several issues:
Problems Caused by Birds Nesting Under Solar Panels
- Damage to Solar Panels
Birds nesting under solar panels can damage the panels and their fixings, potentially voiding the manufacturer’s warranty. Nesting materials and the weight of birds can pull out cabling, causing long-term maintenance problems. - Reduced Efficiency
Feathers, droppings, and nests can accumulate on top of the panels, blocking sunlight and creating hotspots that lower the power output of the solar panel system. - Health Risks
Bird droppings contain harmful pathogens and bacteria, which can cause serious illnesses if inhaled or ingested once the droppings dry and become airborne. - Corrosion
Pigeon droppings are acidic and can corrode and erode brickwork, metalwork, and stonework, leading to damage over time. - Pest Infestations
Birds’ nests often harbour mites, ticks, fleas, and beetles, which can enter buildings and cause further infestations. - Blocked Gutters
Nesting materials, feathers, and droppings can block gutters and drains, causing drainage issues that lead to water damage and costly repairs. - Aggressive Birds
Gulls, in particular, can become aggressive toward people during their breeding season, posing a safety risk to residents and workers.
Why Solar Panel Bird Proofing is the Most Effective Solution
Bird proofing solar panels is a preventative solution that stops birds from nesting beneath panels and eliminates the need for repeated clean-up or culling. Without proper proofing, birds will continually return, as they find the space under solar panels ideal for roosting. Over time, this behaviour is passed on to their offspring, making it a recurring issue for solar panel owners.
It’s important to note that while most birds and their nests are protected by law, pigeons are classified as a pest species, allowing for year-round removal of their nests.
How to Protect Solar Panels from Birds
- Repellent Gel
Repellent gel is a humane method of deterring birds. The gel creates a shimmering effect like fire, while also emitting a pungent odour that repels birds. It remains effective for up to two years and is suitable for a variety of bird species, including pigeons and gulls. - Mesh and Clip System
Professionally installed mesh is one of the most effective ways to prevent birds from accessing the space beneath solar panels. The mesh is secured around the edges of the panels using specially designed clips, ensuring that the panels’ ventilation is not compromised. This method prevents nesting without affecting the manufacturer’s warranty. - Solar-Guard Spikes
If mesh installation isn’t possible, particularly with older solar panels or leased systems, Solar-Guard Spikes are a reliable alternative. These adjustable metal spikes are attached to the sides of the solar panels with strong adhesive, preventing birds from accessing the space underneath. - Anti-Perch Spikes
Anti-perch spikes can be installed on any part of the roof or building where birds might land or perch, including chimneys, lights, guttering, and TV aerials.
For properties in Newcastle, Sunderland, and Durham, protecting solar panels from bird activity is essential for maintaining energy efficiency, avoiding costly repairs, and preserving the integrity of the panels.
