Quick Answer
Bird nesting under solar panels can cause damage to the panels, reduce their efficiency, and lead to costly repairs. The damage can result in increased energy consumption, overheating, or even a complete system failure.
Assessing the Damage
Birds often nest in the gaps or crevices under solar panels, particularly in areas with warm climates or near bodies of water. These nests can cause damage by puncturing the panels, blocking airflow, or introducing moisture. A single bird can cause up to $500 in damage per year, according to some estimates.
Prevention and Deterrents
To prevent birds from nesting under solar panels, install a physical barrier, such as a bird guard or screen mesh, around the panel’s edges. This can be installed during the initial installation or as a retrofit. A 1/4 inch (6 mm) diameter screen mesh is effective in keeping birds out while allowing air to circulate. Alternatively, use a solar panel mounting system with integrated bird-deterrent features, such as a roof-integrated bird guard or a panel with built-in bird screens.
Repair and Maintenance
If bird nesting has already caused damage to your solar panels, inspect the panels for any punctures or blockages. Clean the panels and remove any debris or nesting material. If the damage is extensive, consider replacing the affected panels or consulting a professional for repairs. Regular maintenance, such as cleaning and inspecting the panels, can help prevent future damage and ensure optimal system performance.
