Bird Spikes vs Critter Guard

Two tools, two jobs. Learn which one your solar array actually needs.

Across New Mexico's high-desert climate, solar panels create the perfect sheltered microclimate for birds and rodents. The gap between the panel and your roof stays warm, dry and hidden from predators — exactly what a nesting pigeon is looking for.

The hidden cost

Left unchecked, nesting leads to acidic droppings that corrode roofing and wiring, debris that blocks drainage, and a measurable drop in energy production. Repairs and lost output routinely cost far more than prevention.

The professional fix

A properly installed stainless steel critter guard seals the entire perimeter of your array without drilling into your roof — keeping birds out permanently while preserving your manufacturer warranty. Paired with periodic cleaning, it keeps your system producing at peak efficiency for years.

At Solar Perimeter Defense, every assessment includes a free drone inspection so you can see exactly what's happening on your roof before any work begins.
