Quick Answer
Using mesh barriers under solar panels can create a gap between the panel and the mesh, allowing debris and moisture to accumulate, potentially reducing panel efficiency and lifespan.
Ineffective Bird Deterrent
Mesh barriers are often used as bird deterrents under solar panels, but they may not be as effective as expected. The mesh may not be dense enough to prevent birds from landing on the surface, and birds may still find ways to roost on the panel. In fact, studies have shown that a mesh with openings as small as 1 inch (2.5 cm) can be easily bypassed by birds.
Reduced Panel Efficiency
The gaps created between the mesh and the solar panel can also allow debris, such as leaves and twigs, to accumulate. This debris can block sunlight from reaching the panel, reducing its efficiency and lifespan. According to a study by the National Renewable Energy Laboratory, a 10% reduction in panel efficiency can result in a 10% decrease in energy production over a 25-year period. To mitigate this, it’s essential to ensure that the mesh is properly secured and maintained to prevent debris accumulation.
Alternative Solutions
Instead of mesh barriers, solar panel owners can consider alternative bird deterrents, such as visual deterrents like shiny reflective tape or predator decoys. These methods can be more effective and require less maintenance than mesh barriers. Additionally, installing a roof overhang or a canopy can provide a physical barrier to prevent birds from landing on the solar panel. It’s essential to consult with a solar panel professional to determine the best bird deterrent solution for a specific installation.
