Pigeons under solar panels: signs, risks and what to do
The gap between your panels and the roof is a warm, dry, sheltered space, which is exactly what a pigeon looks for. Here is how to tell if birds have moved in, what they can damage, and the sensible next steps.
Why pigeons choose the space under solar panels
Panels are mounted on rails a few centimetres above the roof covering. That leaves a cosy gap with shade in summer, shelter from rain and wind, and protection from predators. Warmth from the roof and the panels themselves makes it even more attractive in colder months. Once one pair settles, others tend to follow, and birds often return to the same spot year after year.
Signs you have birds under your panels
- Cooing, scratching or fluttering noises from the roof, especially early morning and at dusk.
- Droppings, feathers or twigs on the roof tiles, in the gutters or on the ground below the array.
- Birds repeatedly flying in and out at the lower or side edge of the panels.
- Straw, twigs or debris poking out from under the panel edge.
- Streaking or staining on the panel glass below the frame.
- A drop in generation that cannot be explained by weather or shade.
A pair of binoculars from the ground, or a look at your inverter app for unexplained dips, is a safe way to check without going on the roof. Do not climb onto the roof yourself to look.
What damage can pigeons cause?
Cables and fittings
The wiring under an array is exposed to anything that can reach it. Birds can peck at or pull on cables and connectors, and nesting material can build up around them. Repairs are usually far more expensive than prevention.
Fire risk
Dry twigs and nesting material packed against electrical components are a concern. It is not a common event, but it is the reason many installers and insurers take nests under panels seriously.
Droppings and cleaning
Droppings are corrosive over time and can stain and mark roof coverings and panel frames. They also carry bacteria and parasites, so clearing a long-established nest is a job for someone with protective equipment. Ask a specialist about this rather than tackling it with a brush and hose.
Output and heat
Droppings on the glass shade the cells, and on some systems one shaded panel can pull down the output of the rest of the string. Nests can also restrict airflow under the panels. The effect on generation is usually modest, but it adds up across a year.
Noise and mess
Many homeowners first notice the problem because of noise, or because droppings land on windowsills, patios and cars below.
What to do if pigeons are already there
- Check for eggs or chicks if you can do so safely from the ground. In the UK, wild birds' active nests are generally protected, so nests with eggs or young should not be disturbed. The rules are more nuanced than that, so see our guidance on removal before acting.
- Do not block the entrance while birds may be inside. Trapping birds under panels is both cruel and potentially unlawful.
- Do not go on the roof. Falls from roofs are a serious cause of injury, and panels can be slippery and fragile.
- Get a specialist to assess it. They can clear the area when it is lawful to do so, clean up, and fit mesh so the birds cannot return.
Spikes and scare devices rarely solve it. Birds sitting on the ridge are a symptom. The real fix is to close off the gap under the panels, which is what bird proofing mesh does.
How to stop them coming back
The standard, long-lasting solution is a mesh skirt fitted around the edge of the array, held on with clips so birds cannot get underneath. Read our guide to bird proofing mesh to understand the materials and fixings, and our cost guide for typical prices, which usually run from about £300 to £800 for a standard home.
Frequently asked questions
How do I know if pigeons are nesting under my solar panels?
Cooing and scratching sounds from the roof, droppings and twigs around the array, and birds regularly flying in and out under the panel edge are the usual signs. Check from the ground rather than climbing onto the roof.
Do pigeons damage solar panels?
The panels themselves are fairly robust, but pigeons can damage cables and fittings underneath, and droppings can stain and mark surfaces. Nesting material near electrical components is also a fire concern. The sooner the gap is sealed, the lower the risk.
Is it safe to leave pigeons under my solar panels?
It is not recommended. Over time you risk damage to wiring, a build-up of droppings and debris, and higher cleaning and repair costs. A specialist can assess the situation and advise on the safest and lawful way to deal with it.
Can I just put spikes on my solar panels?
Spikes stop birds perching on ledges, but they do not seal the gap underneath the panels, which is where pigeons nest. A mesh skirt around the array is the usual solution.
How much does it cost to remove pigeons from solar panels?
A typical home often costs somewhere between £300 and £800 for professional proofing, though long-established nests, difficult access and larger arrays can push the price up. Treat this as a guide only and get a written quote.
