How to deal with wasps or birds nesting near solar panels?

Identifying and Addressing the Issue

When wasps or birds take up residence near solar panels, it can lead to reduced energy efficiency and potentially even system damage. Before taking action, inspect the panels and surrounding area to determine the extent of the infestation. If the nesting site is accessible, consider hiring a professional to humanely relocate the pests. If the nest is too high or in a hard-to-reach location, consider installing a bird-repellent net or wasp screen around the affected panels.

Installing a Physical Barrier

Bird-repellent nets can be installed over individual panels or entire arrays to prevent birds and other pests from landing and nesting. These nets come in various mesh sizes and are typically made of durable, weather-resistant materials. When selecting a net, consider the local bird species and their preferences for nesting materials. For example, birds may prefer a mesh size of 1 inch or larger to accommodate their nesting materials. Install the net at least 3 feet away from the panels to ensure proper airflow and prevent heat buildup.

Cleaning and Maintenance

After relocating the pests or installing a physical barrier, it’s essential to thoroughly clean the solar panels to remove any debris, nests, or droppings. Use a soft-bristled brush and a mild soap solution to gently scrub the panels, taking care not to scratch the surface. Rinse the panels with a hose and allow them to dry completely before reassembling any netting or screens. Regular maintenance, including cleaning and inspecting the panels, can help prevent future infestations and ensure optimal energy production.
