Solar panels sit a few inches above the roof, and when that gap is unprotected, it creates the perfect shelter for feral pigeons to nest. We fit solar panel bird netting and mesh across the UK to seal the gap before it becomes an established nesting site, as part of our professional pest bird control service.
Why pigeons nest under solar panels
A solar panel raised a few inches off the roof creates a sheltered space. The panel holds heat and the roof radiates it back, so the gap stays warm. Rain runs off the panel above rather than into the space underneath, and cats, foxes, and other ground predators cannot reach it.
Feral pigeons take to the underside of solar panels most readily, and they are the species we deal with under arrays far more than any other, though gulls, starlings, and sparrows will use the space too if the gap suits them. Pigeons are loyal to a roost, so a pair that nests under your panels one spring will return the next, bringing their offspring with them. Nesting materials build up underneath, droppings accumulate, and within a couple of seasons of birds nesting under panels the array is heavily fouled.
The damage birds do to a solar panel system
Birds under a solar array do more than make a mess. Left alone, a nesting colony costs you generation and damages the roof structure underneath.
Droppings, shading, and lost efficiency
Bird droppings are acidic, and a buildup of guano on and around the panels etches into the surface over time. Droppings that land on the cells themselves are an obstruction, blocking sunlight from reaching the solar cell beneath, and even partial shading across a panel can drag down the output of the whole string it sits in. A solar PV system fouled this way simply generates less, and the reduced efficiency carries on until the panels are cleaned and protected.
Blocked ventilation, gutters, and nesting materials
Solar panels are designed to run with air moving freely across their underside, because trapped heat lowers their output. A nest packed into the gap becomes an obstruction to that ventilation and holds heat against the panels. Nesting materials, feathers, and debris also wash down into the gutters, where they cause blockages, overflowing rainwater, and damp on the wall below.
Damage to wiring and health risks
Pigeons peck at whatever is within reach, and the electrical wiring clipped beneath a solar panel installation is an easy target. Pecked cable is physical damage to a live electrical system, and a fire and shock hazard. The droppings carry a health risk of their own. Dried guano harbours bacteria and can spread disease, including psittacosis, and old nests are a habitat for mites and other parasites.
How solar panel bird netting and mesh works
Solar panel bird-proofing, sometimes called pigeon-proofing, closes the gap around the edge of the array, preventing birds from getting underneath it. Closing the gap is the only reliable way to stop bird nesting under a solar array. The mesh physically excludes birds rather than scaring them off, and visual and audible scarers stop working once birds learn they are harmless, but a sealed gap gives them nothing to get used to, so solar panel exclusion holds for as long as the mesh stays sound. The system has two parts, the mesh and the clips that hold it.
Galvanised, PVC-coated steel mesh
The mesh is a galvanised steel wire mesh with a black PVC coating. The galvanising protects the steel from rust, and the PVC coating adds a second layer of weather protection while keeping the mesh discreet against the dark frame of the panels. It is rigid enough to hold its shape and fine enough to stop a pigeon pushing through. Uncoated wire mesh corrodes and sags within a season or two of outdoor use. The galvanising and PVC coating on this mesh prevent that, so a PVC-coated solar panel mesh stays sound for years and is long lasting.
Non-penetrative solar panel clips
The mesh is held in place with solar panel clips that grip the lip of the panel frame. Nothing is drilled, screwed, or glued, and neither the roof nor the panels are penetrated, so the work does not affect your solar panel installation warranty. The clips space the mesh slightly off the panel edge, which keeps airflow and ventilation under the array intact. Together, the mesh and clips make a secure installation, with no gaps left along the edges for a bird to push through.
Do you need solar panel bird-proofing?
Not every solar array attracts birds, and we will tell you straight if yours does not need protecting. Panels mounted tight to a low-pitch roof, with little gap underneath and no real bird pressure on the site, may be fine left alone. Solar panel bird mesh is not something every solar panel owner has to buy.
Mesh is worth fitting when there is a reachable gap under the panels and pigeons in the area, and plenty of UK rooftops meet both. If you have already heard birds on the roof, or seen droppings or nesting material at the panel edge, the array needs proofing before the next breeding season, while the potential damage is still limited. At that point, mesh is a highly effective way to protect your solar panels, and it costs less than cleaning guano, clearing gutters, and replacing pecked cable year after year. When you are not sure, a free survey will tell you either way.
Professional installation or a DIY solar panel bird proofing kit?
DIY solar panel bird proofing kits are sold widely, and on paper they look like a simple job. In practice, the result depends almost entirely on the fit. A mesh fixed with cable ties rather than proper clips is the most common shortcut, and cable ties left in sunlight grow brittle and snap, usually within a year, leaving the mesh hanging and the gap open again.
The bigger issue is the work itself. Fitting mesh around solar panels means working at height, on a pitched roof, leaning around panels and live cabling. Our installers are trained and certified for working at height and carry the right access equipment for the job. We measure the array, cut the mesh to fit each run, and seal the perimeter properly so no corner is left for a bird to slip past. A kit fitted in a hurry from a ladder rarely seals every corner, and one open gap is enough for a pigeon to get back under the panels.
How we install solar panel mesh
- Free survey. We visit the property, check the array and the gap beneath it, identify which birds are using it, and confirm whether mesh is the right answer. You get a written, fixed-price quote with no obligation.
- Cleaning and decontamination. If there are existing bird droppings and nesting material under the panels, we remove and disinfect them first. Sealing mesh over old guano traps the mess and the scent inside, so the area is always cleaned before proofing.
- Mesh installation. We measure each side of the array, cut the PVC-coated protection mesh to length, and fix it around the perimeter with non-penetrative clips. Every run is checked for gaps as we go.
- Final inspection. Once the panels are protected, we walk the whole perimeter to confirm the mesh is secure and the array is fully sealed against birds. All work is carried out safely at height with the correct access equipment.

Solar panel bird netting: your questions answered
How much does it cost to install bird netting on solar panels?
The cost depends on the size of the array, how many panels need surrounding, the height and pitch of the roof, and the access equipment required. A standard domestic array is a straightforward job, while a large or hard-to-reach roof takes longer and the labour costs reflect that. We give every customer a fixed written quote after the survey, so the price is clear before any work starts. Set against repeated guano cleaning, gutter clearing, and cable repairs, mesh is the more cost-effective route over the life of the panels.
What is the best bird-proofing for solar panels?
For the gap under a solar array, mesh fixed with panel clips is the standard, because it seals the whole perimeter and needs no drilling. Bird spikes and wire suit open ledges and parapets rather than the panel gap, and a deterrent gel does not exclude anything. On a roof with a wider bird problem, mesh on the array can be combined with spikes or wire on the ridge. The survey works out the right mix for your roof.
Will the mesh damage my solar panels or void the warranty?
No. The clips grip the edge of the panel frame, and nothing is drilled, screwed, or glued, so there is no physical damage to the panels or the roof and no effect on your warranty. The mesh sits slightly off the panel edge, so airflow under the array carries on as the manufacturer intended.
How durable is the mesh in bad weather?
Galvanised, PVC-coated steel mesh is a durable material built for permanent outdoor use. The galvanising and the PVC coating together resist rust and weather, and the mesh holds its shape through wind, rain, frost, and snow. Fitted with proper clips rather than cable ties, a solar panel mesh installation lasts for many years with no real maintenance.
Can you fit mesh to panels that are already installed?
Yes. Most of the solar panels we proof have been up for a few years already, often fitted long before birds found them. The mesh and clips work on installed solar panels of almost any age or make, and we can survey and fit around an existing array without the original solar panel installer being involved.
Is solar panel bird mesh humane?
Yes. The mesh works by closing off the space, not by trapping or hurting anything, which makes it a sound choice for wildlife protection. Birds arrive, find they cannot get under the panels, and move on to nest elsewhere. Deterring birds this way keeps them out without harming the pest birds or local wildlife. Loose or badly fitted mesh is the only thing that poses a risk to birds. Professional installation prevents that.
How do you clean bird droppings off solar panels?
Bird droppings on the panels should be removed by someone equipped to work safely at height, using methods that will not scratch the cells. Dried guano is also a health risk and needs careful handling. We clean and decontaminate the array as part of the proofing job, so the panels are clear before the mesh goes on. Bird fouling removal is also available as a standalone service.
Where can solar panel bird guards be installed?
Solar panel bird guards and mesh can be fitted to almost any roof-mounted array, on houses, flats, schools, farm buildings, warehouses, and commercial premises. Pitched or flat roof, a few panels or a few hundred, the mesh and clip system scales to the job. For wider bird control for roofs, the same survey can cover ridges, gutters, and chimney stacks at the same time.
Arrange your free solar panel bird-proofing survey
If pigeons are already nesting under your solar panels, the problem grows with every breeding season the gap stays open. Fitting the mesh is a one-off job, and it protects your solar panels from birds for years, along with the roof underneath. Once the array is sealed, no birds are harmed and none can get back in.
Call 0800 027 2555 (freephone, 24/7) or request your free survey online. We will inspect the array, give you honest advice on whether proofing is needed, and quote a fixed price before any work begins.
