Quick Answer
Choose a critter guard size that is at least 3 inches wide and covers the entire length of the solar panel's array, taking into account the width of the panel and any obstructions like mounting hardware.
Measuring the Solar Panel
To determine the right size for critter guards, first measure the width of your solar panel array. For most residential solar panels, this is around 60 to 72 inches. Next, consider any obstructions like mounting hardware or edge sealants that may affect the guard’s fit. Add an extra 6-8 inches to account for any overhang or overlap.
Choosing the Correct Material
Critter guards can be made from various materials, including stainless steel, aluminum, and plastic. When choosing a material, consider factors such as durability, corrosion resistance, and UV stability. For example, stainless steel or 316-grade aluminum are good choices for coastal areas due to their high corrosion resistance. Plastic guards, on the other hand, are a cost-effective option for areas with low bird traffic.
Installation and Placement
When installing critter guards, ensure they are securely attached to the solar panel array to prevent wind-driven debris or birds from dislodging them. Consider using a 3M VHB tape or a similar product to attach the guard to the panel. Place the guard as close to the panel’s edge as possible to prevent birds from landing on the guard itself.
