Can wildlife damage pole-mounted solar installations in rural settings?

Wildlife Hazards to Pole-Mounted Solar Installations

Wildlife such as birds, squirrels, and deer can cause damage to pole-mounted solar installations, mainly due to their natural instinct to climb or perch on structures. For instance, birds may build nests on the solar panels, causing electrical short circuits and reducing energy output. According to the National Renewable Energy Laboratory (NREL), up to 20% of solar panel failures can be attributed to wildlife-related damage.

Prevention and Mitigation Techniques

To prevent wildlife damage, installers can use various techniques such as installing bird spikes or netting around the solar panels, or using wildlife-resistant mounting systems like those made from durable materials like steel or aluminum. For example, a study by the University of California, Berkeley found that installing bird spikes on solar panels reduced bird-related damage by up to 90%. Additionally, installers can also use squirrel-resistant connectors and wiring to prevent squirrels from accessing the electrical system.
