🐿️ Critter Control: Keeping Pigeons and Squirrels Out of Your Array

The gap between the solar panels and the roof is a perfect shelter for pests, leading to noise, nesting, and dangerous wire damage.

1. The Pest Problem

The main culprits are squirrels, birds (especially pigeons), and occasionally raccoons.

• ✅ **Squirrels/Rats:** Their chewing can destroy valuable wiring (DC cables, optimizer/micro-inverter connections), posing a fire risk.
• ✅ **Birds/Pigeons:** Droppings accumulate, blocking light and reducing panel efficiency significantly. Nesting debris can also block airflow and cause overheating.

2. The Solution: Solar Critter Guard

The most effective and common method is a protective mesh barrier.

• **Metal Mesh:** A durable, PVC-coated metal mesh is fastened around the entire perimeter of the panel array, physically blocking access to the gap.
• **Installation:** It must be securely installed without penetrating the roof or panel frames to maintain warranties.
• **Gutter Clips:** The mesh is usually held in place by specialized clips that attach to the panel frames.

Airflow and Warranty

A properly installed critter guard maintains essential airflow beneath the panels (needed for cooling and efficiency) while still providing total protection from pests. Ask your installer if this is included in your package. 💡
