How to Install Mesh Around Solar Panels: A Comprehensive Guide

The first step to ensuring productive solar panel usage is by protecting them from pest intrusions. The installation of a fine mesh around solar panels acts as a barrier to keep pests at bay without affecting the performance of the panels. Generally, the use of solar panel protection mesh prevents birds, rodents, and other pests from compromising the underside of the solar array, thereby reducing maintenance costs and extending the lifespan of the solar panels.

Always remember that solar panels are live and carry DC voltage. Ensure you understand the system and know how to prevent electric shock before starting work. When in doubt, consult a pest controller, solar panel installer, or electrician for professional assistance.

Preparing for Installation

Safety Measures

Bird droppings and nesting materials often contain harmful organisms that can transfer diseases to humans, such as Ornithosis, Chlamydia, E-coli, and Salmonella. Nests and feathers might also harbor biting insects like Red Mites, Ticks, and Fleas. Clean the work area thoroughly using products such as Guanaway or PX Ornikill, following manufacturer instructions and local wildlife protection regulations. Always use appropriate personal protective equipment (PPE).

Working at Height

Working at height poses risks. Use proper access equipment like roof ladders, scaffolding, or mobile elevated work platforms to ensure safe access to the work area. Wear fall arrest equipment and avoid working in hazardous weather conditions.

Tools and Materials Required

• Solar panel mesh (made of coated steel to prevent rusting)
• Solar panel mesh clips (e.g., Bird B Gone Solar Clips)
• Avian disinfectant (e.g., PX Ornikill or Guanaway)
• Wire cutters
• Protective gloves
• Timber for straight edge

Step-by-Step Installation Guide

Step 1: Cleaning

Thoroughly clean the solar panels to remove all traces of bird droppings and nesting debris. Use an avian disinfectant and follow manufacturer's instructions. Wear necessary protective gear during the cleaning process.

Step 2: Cutting the Mesh

Cut the welded mesh roll into manageable sections, typically around 2 meters long. This makes it easier to handle the mesh at height. Always wear protective gloves as the mesh edges can be sharp.

Step 3: Preparing the Mesh

Using a piece of timber as a straight edge, fold the mesh about one-third of the way from the outside edge at a 30-degree angle. This helps in locking the mesh into position when applying the retaining clips.

Step 4: Installing Mesh Clips

Slide the mesh clips into position on the underside lip of the solar panel. Typically, use 2 clips on the panel’s short edge and 3 clips on the long edge, increasing as necessary where mesh panels overlap.

Step 5: Attaching the Mesh

Line up the mesh holes with the clips installed earlier and slide the mesh over the serrated shaft of the clip, securing it with the locking disc. Ensure the alignment is correct before pushing the locking disc all the way to secure the mesh against the panel and roof.

Step 6: Corner Installation

Start from an outer corner and work towards the middle of the panel array. Cut the mesh at a 45-degree angle at the bent section for neat corners and overlap adjoining panels by 8-10 squares, securing them with clips.

Step 7: Handling Obstructions

Carefully cut around any obstructions such as mounting brackets and wiring, ensuring no gaps larger than 50mm are left to prevent pigeons from gaining access.

Step 8: Finishing Touches

Trim excess mesh with wire cutters, ensuring it is flush with the top edge of the solar panel frame. Trim any leftover tails from the mesh clips to give a neat finish.

Bird Control Options

Post-Installation Considerations

Even after mesh installation, birds may linger due to pheromones in droppings. It's recommended to install bird control products like bird spikes to prevent birds from perching near the panels.

Reducing Bird Populations

Trapping programs can effectively reduce bird populations around the installation area. Use humane traps with shade, food, and water to attract and safely release birds away from the property.
