Solar pigeon proofing is not a cheap installation, so it is important to ensure the work is carried out correctly the first time. Poorly installed mesh systems can fail, allow pigeons and pests back under the panels, damage your roof or solar system, and in some cases even affect the manufacturer’s warranty. A professionally installed system should provide long-term protection while maintaining the appearance and performance of your solar panels.

One of the most important things to understand is that solar pigeon proofing should never involve drilling or screwing directly into the solar panels or frames. This can damage the system and may invalidate the manufacturer’s warranty. Professional installers should always use proper solar panel clips designed specifically for solar pigeon proofing. These clips should be UV-stabilised or stainless steel and designed to securely attach to the panel frame without causing any damage.

The type of mesh used is also extremely important. Proper solar pigeon proofing mesh should be either plastic-coated galvanised steel, hot-dipped galvanised steel, or stainless steel. In our experience, plastic-coated mesh is often the most durable and visually discreet option, although all professional-grade solar mesh systems can perform well when installed correctly. The gauge of the wire also matters. A 19-gauge mesh may be suitable for pigeon-only protection, however for squirrels and rodents a stronger 16-gauge mesh is generally considered the industry standard as it cannot easily be bent or damaged.

The aperture size of the mesh should also be carefully selected. For pigeon proofing, a 12.5 mm x 25 mm mesh is commonly used as it still allows excellent airflow beneath the solar panels. Where squirrels or smaller rodents are present, a smaller aperture may be required to prevent pests from squeezing through gaps.

The environment around the property should also be considered when choosing materials. Hot-dipped galvanised steel is a cost-effective and commonly used option with good durability. PVC-coated galvanised mesh provides additional rust protection along with a discreet matte black finish. Stainless steel offers the highest corrosion resistance and is particularly recommended for coastal or high-salt environments where rust protection is especially important.

Correct installation is just as important as the materials themselves. Solar clips should generally be installed at approximately 450 mm intervals around the solar array to prevent birds or rodents from forcing their way behind the mesh. The bottom edge of the mesh should also be bent outward at roughly a 30 to 45-degree angle to create what is commonly known as a “kick-out.” This allows the mesh to sit tightly against the roof tiles and helps prevent pigeons from gaining access underneath the system. On some roof tile profiles, the mesh may also require trimming carefully to follow the shape of the tiles and remove any potential gaps.

Another very important consideration is ensuring the mesh does not protrude above the edge of the solar panels. If the mesh sits too high, it can create shading on the panels which may lead to hot spots or “shade burn.” Over time this can reduce efficiency and potentially damage the solar cells. A properly installed system should sit neatly below the edge of the panels while maintaining a clean and discreet appearance.

Achieving a professional finish also requires care during installation. Working one side at a time helps avoid kinks or bends in the mesh and results in a tighter, cleaner fit. Corners where two lengths meet should be trimmed neatly and securely folded together to lock the sections in place. Additional ties may sometimes be used for extra reinforcement where required. Most importantly, there should never be gaps or openings where pigeons or pests can enter.

Solar pigeon proofing is far more than simply attaching mesh around solar panels. A proper installation requires the correct materials, proper fitting methods, knowledge of solar systems, and attention to airflow, shading, and pest-proof detailing. We always recommend using an experienced installer who specialises in solar pigeon proofing and provides a genuine workmanship warranty.

At Solar Pigeon Proofing Service, we provide professional solar pigeon proofing installations using high-quality materials and non-invasive fixing methods designed to protect both your roof and your solar panels. All of our installations come with a 5-year warranty on materials and workmanship for complete peace of mind.
