What should I do about birds nesting beneath solar panels?

What you will see

• Birds repeatedly entering the same gap beneath the array.
• Nesting material visible from a safe position.
• Heavy, recurring soiling on part of the panel surface.
• Debris accumulating near equipment or a roof drainage route.
• These signs do not establish that a cable has been damaged or that nesting is the sole cause of reduced output.

Why it happens

Shading and contamination of a module’s light-receiving surface can affect production. The significance depends on the actual affected area and system arrangement; bird activity alone does not establish a particular energy loss.

The inspection should also include accessible cable routes and supports. PV maintenance guidance treats animal access and cable condition as matters to address together where damage is found.

Any proposed exclusion system should be reviewed with the installer. Ask how it will preserve drainage, equipment clearances and future access, and how it will be attached without damaging modules or roofing. A competent bird-control provider should advise on the appropriate handling of an occupied nest and any applicable local requirements.

What nesting can affect

Panel surface

Droppings shade cells and cut output.

Cables and supports

Access and chewing need checking.

Roof drainage

Debris can block water routes.

Any exclusion system must keep drainage, clearances and future access.

What you can check yourself

• Note the entry location from ground level or another safe position.
• Record when activity started and whether it is recurring.
• Save photographs that do not require approaching the nest.
• Mention nearby blocked drains or substantial visible debris.
• Provide production records if performance has also changed.
• Access beneath an array should be planned by the attending team, particularly where the roof is difficult to reach.

What not to do

• Do not spray nests or wiring, use fire or smoke, or push tools under panels. Do not fasten improvised mesh through a module or block vents and drainage routes. Avoid walking on panels to reach a nesting area.

When to call us

• Arrange an inspection when nesting is persistent, cable damage is suspected or debris is affecting access and drainage. Visible electrical damage requires prompt attention.
