Mitigating bird droppings on solar panels involves several strategies. When panels do not get full sunlight, their energy production drops. Bird-proofing measures, such as mesh barriers, spikes, and solar skirts, start from £50 per panel, saving homeowners thousands of pounds in. Install physical bird deterrents like spikes, netting, or wire coils to create an inhospitable surface that prevents birds from landing or nesting under your solar panels. Utilize ultrasonic devices or visual deterrents such as reflective tape, predator decoys, or holographic strips to scare birds. These feathered friends leave behind droppings, guano, and feathers that can damage your panel's surface and reduce its efficiency.
