Quick Answer
The direct answer is good, but could briefly mention the immediate damage from droppings (corrosion, shading) and nesting materials (fire hazard) to underscore *why* it's important to address the issue, not just *that* it's an issue.
Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Start on the ground. Use binoculars to visually inspect the edges of your solar array for visible nests, droppings, and bird activity. Do this at dawn or dusk.
Step 2
Just listen. Stand quietly near the area of the roof with the panels and listen for cooing, scratching, or chirping. It's a dead giveaway.
Step 3
If you are completely comfortable and can do so safely, perform a quick visual inspection from a ladder or on the roof. Look for nesting material and the extent of the droppings. Do not stick your hand under the panels.
DIY vs Professional Costs
| Repair Type | DIY Cost | Professional Cost | Time Required |
|---|---|---|---|
Critter Guard Kit Installation | $100 - $300 | $500 - $1,500 | 4-8 hours |
Heavy Cleaning & Critter Guard Installation | $120 - $350 | $700 - $2,500+ | 6-10 hours |
When to Call a Professional Solar
- If you are not comfortable with heights or your roof is steep, slippery (tile/metal), or more than one story high.
- If you see any signs of chewed or damaged wiring under the panels. This is a fire and shock hazard that needs a qualified technician.
- If the infestation is severe, with a large number of nests and a heavy accumulation of droppings that requires a biohazard-level cleanup.
- If you just want the job done quickly, correctly, with a warranty, and without spending your entire weekend on your roof.
Prevention Tips
- The absolute best prevention is to install a professional-grade PVC-coated wire mesh critter guard around the entire perimeter of your solar array.
- If you are installing a new solar system, insist that the installers add a critter guard as part of the initial installation. It's much cheaper and easier then.
- Don't waste money on gimmicks like plastic owls, reflective tape, or ultrasonic noise makers; birds get used to them quickly and they are not a long-term solution.
