Do solar arrays without gaps have a lower chance of bird nesting?

Reducing Bird Roosting on Solar Panels

Birds commonly target solar panels with gaps or open areas, as these spaces provide an ideal location for nesting and roosting. Solar arrays without gaps can significantly reduce the likelihood of bird nesting by eliminating these potential roosting sites. A study found that solar panels with gaps as small as 1 inch in width can attract birds and other wildlife, which can lead to damage and reduced energy production.

Designing Gap-Free Solar Arrays

To prevent bird nesting on solar panels, designers and installers can employ several strategies. One approach is to use solid black or dark-colored panels, which can be less attractive to birds than traditional silver or white panels. Another technique is to use a grid pattern with smaller gaps, as this can make it more difficult for birds to land and nest on the panels. For example, a grid pattern with 0.5 inch gaps may be more effective than a grid pattern with 1 inch gaps.

Bird Deterrent Methods for Existing Arrays

For existing solar arrays with gaps, there are several bird deterrent methods that can be implemented. One option is to install a bird-friendly mesh or screen around the solar panels, which can allow sunlight to pass through while preventing birds from landing. Another approach is to use visual deterrents, such as reflective tape or streamers, which can scare birds away from the solar panels. By implementing these methods, solar array owners can reduce the risk of bird nesting and maintain the efficiency of their solar panels.
