Birds nesting under solar panels is a widespread issue across the UK. While solar systems are designed for efficiency and longevity, unwanted guests such as pigeons can cause surprising levels of disruption. These birds are drawn to the sheltered space beneath the panels, where they build nests, leave droppings, and sometimes damage wires or insulation. Fortunately, there is a simple and effective solution: solar panel mesh.
This blog will explore the importance of protecting your panels, explain how solar panel mesh works, and guide you through choosing the right materials. Throughout the article, we’ll highlight options available at The Mesh Company, helping you find reliable, long-lasting bird-proofing solutions.
Solar panels provide ideal nesting conditions: warmth, shelter, and protection from predators. Pigeons, in particular, are known to settle in these spots, creating:
Noise disturbances
Nest debris buildup
Corrosive droppings on roofing
Blocked airflow beneath panels
Additionally, nesting materials can present a fire hazard or lead to panel overheating, reducing efficiency.
Solar panel mesh is a physical barrier that blocks access to the underside of the panels without affecting their functionality. By installing a durable mesh around the perimeter of your solar array, you can:
✔ Prevent pigeons and other birds from nesting underneath
✔ Maintain the system’s efficiency and airflow
✔ Avoid costly cleaning and repairs
✔ Protect roof tiles and insulation from damage
Not all mesh is created equal. For outdoor applications, you need a product that offers:
Corrosion resistance: Especially important in coastal or damp areas
Fine aperture: Small enough to keep birds out, but not so dense it restricts airflow
UV stability: To withstand constant sunlight exposure
Easy installation: Suitable for clipping to standard panel frames without damage
✅ Recommended Product: Stainless Steel Insect Mesh – 1.2mm Aperture, 0.23mm Wire – Durable, rust-resistant, and perfect for long-term solar protection.
Highly resistant to corrosion and weathering, stainless mesh is ideal for permanent installation.
Long lifespan (10+ years outdoors)
Maintains structure in extreme heat or cold
Aesthetically neutral
✅ Great for: Long-term bird-proofing with minimal maintenance
A cost-effective alternative for medium-term protection.
Zinc coating resists rust
Available in various gauges and apertures
Easier to cut and shape
✅ Great for: Shorter-term solutions or low-exposure roofs.
Offers a discreet look that blends in with black panel frames.
UV-protected plastic coating
Added resistance to corrosion and weathering
Flexible for awkward roof shapes
✅ Great for: Visual integration on modern or domestic solar installations.
Selecting the correct aperture size is key. Below is a quick comparison of common sizes:
| Aperture Size | Mesh Type | Use Case |
|---|---|---|
| 1.2 mm | Insect Mesh | Maximum bird prevention, minimal visibility |
| 6 mm | Welded Wire Mesh | Strong and effective for pigeons |
| 12 mm | Galvanised Chicken Wire | Budget option for large roof arrays |
Smaller apertures (1–2 mm) are recommended for total exclusion. These prevent not only birds but also nesting insects such as wasps or bees.
Here’s a quick guide to a typical installation:
Remove any existing nests, droppings, and debris using gloves and protective gear.
Using heavy-duty scissors or a mesh cutter, cut strips to the perimeter length of your panels.
Use solar mesh clips or J-hooks to secure the mesh to the frame. Avoid screwing into the panel.
Ensure corners are overlapped and tied with stainless steel wire to avoid gaps.
While stainless steel mesh is durable, it’s good practice to inspect yearly for any loosened sections.
A customer from Greater Manchester contacted The Mesh Company after birds began nesting under their 14-panel rooftop system. Using our 304 stainless steel insect mesh and a set of J-hooks, they created a seamless barrier within a day. A year later, the system remains bird-free with no damage or wear to the mesh.
| Feature | Stainless Steel | Galvanised Steel | PVC-Coated Steel |
| Corrosion Resistance | Excellent | Moderate | High |
| Appearance | Metallic | Silver | Black (discreet) |
| Cost | Higher | Lower | Moderate |
| Lifespan | 10+ years | 3–5 years | 7–10 years |
❌ Using plastic mesh, which is easily chewed or weather-damaged
❌ Leaving gaps at corners or under mounting rails
❌ Failing to clean droppings before installation (can corrode surfaces)
❌ Forgetting to check local wildlife regulations (especially for bats or protected birds)
✔ Keeps birds and pests from nesting
✔ Maintains panel airflow and energy efficiency
✔ Prevents fouling damage and roof staining
✔ Easy to install with no specialist tools
✔ Long-term protection without visual impact
For maximum longevity, choose stainless steel with a fine aperture.
Match the mesh colour to the panel trim (e.g., black PVC for black frames).
Always use non-invasive fixing methods to avoid voiding warranties.
✅ Suggested Product for Most Installations: 1.2mm Aperture Stainless Steel Mesh Roll – 30cm width – Ideal width for common residential solar panel clearance.
