Pigeon Deterrent for Solar Panels in San Francisco
Pigeons love to nest under rooftop solar arrays. We install metal mesh around the array to keep birds out. The mesh is secured to the panel frames with slide-clamp washers — no drilling into your panels, and once it’s on, it’s not going anywhere. We also offer other deterrent options.
