Solar panel bird proofing

What's typically involved

• Cleaning out nests and debris under the panels
• Cleaning the panels
• Installing mesh guards around the edges, attached without drilling at many companies

Good to know

Ask how the guard attaches, whether it affects your installer's warranty, and how long it's expected to last.

Methods, products and prices vary by company. Ask each one how they clean, what they use and what's included.

Signs pigeons are nesting under your panels

• Cooing or scratching sounds from the roof
• Droppings on the panels, roof and walkways below
• Twigs and debris sticking out from under the array
• Birds flying in and out at the panel edges

What a bird-proofing job usually includes

1. Removing nests, debris and droppings from under the panels
2. Cleaning the panels and roof area
3. Attaching mesh around the array's edges, often with clips designed for solar frames
4. Photos of the finished job at many companies

Questions to ask

• How does the mesh attach, and does it involve drilling?
• Will it affect my installer's warranty?
• How long is the mesh expected to last in SoCal sun?
• Is there a guarantee if birds get back in?

Why pigeons choose solar panels

The gap under a rooftop array is shaded, sheltered from wind and close to food sources, which makes it ideal for pigeons, especially in urban and suburban SoCal. Once a pair nests, more tend to follow. Droppings can build up on panels and roofs, and nesting material can collect along wiring and drains. Blocking access around the array's edges is the usual long-term fix; cleaning alone tends to be temporary.
