Solar Add-Ons: Critter Guards, Panel Skirts, Extended Protection & More
Protect your solar investment with critter guards, panel skirts, and extended coverage. Learn which add-ons are worth it and when to bundle upgrades.
In this article
Solar panels are a long-term investment. They sit on your roof for decades, quietly converting sunlight into electricity while exposed to weather, wildlife, and time.
Add-ons do three jobs on a solar project: they keep wildlife out of the space under the array, they keep the installation looking the way you want it from the street, and they extend the service coverage on the system. Which ones are worth it depends on your roof, what is growing around it and how long you plan to own the house.
This guide covers each option, what it costs and the situations where it earns its place.
Why Protecting Your Solar System Matters
Solar panels are designed to produce power for 25 or more years with minimal maintenance. The panels handle weather well. What add-ons address is the environment around them, which varies a lot from one property to the next.
Solar panel maintenance guide.
The gap between panels and roof is warm, dry and sheltered, which makes it attractive to squirrels, birds and other animals looking for nesting spots. Nesting brings debris and moisture, and squirrels will chew wiring they can reach.
This is mostly a question of what is around your house. Mature trees, a wooded lot or a known squirrel population make critter guards worth doing at installation, when the crew is already on the roof and the cost is a few hundred dollars rather than a separate service call later.
Critter Guards: The Most Practical Solar Add-On
Critter guards are metal mesh barriers installed around the perimeter of a solar array. Their purpose is simple: block animals from nesting beneath your panels.
Why Critter Guards Matter
The space under solar panels is prime real estate for wildlife. It’s protected from rain, wind, and predators, ideal for nesting. But what’s comfortable for animals is damaging for your system:
- Squirrels chew wiring, causing shorts and production loss
- Birds build nests that trap moisture and debris
- Rodents leave droppings that corrode components
- Nesting materials create fire hazards near electrical equipment
Removing animals and repairing damage after the fact is expensive and disruptive. Critter guards prevent the problem entirely.
Cost Perspective
Critter guards typically cost a few hundred dollars when installed with your solar system. Squirrel damage repairs can run $1,000–$3,000 or more depending on severity. Prevention is almost always cheaper than repair.
Who Needs Critter Guards Most
Homes near trees, wooded areas, parks, or overhead utility lines are especially prone to wildlife issues. But even suburban neighborhoods without obvious wildlife corridors see squirrel and bird activity.
If you have trees within 50 feet of your roof, critter guards are strongly recommended.
Panel Skirts: Clean Lines and Curb Appeal
Panel skirts are trim pieces installed along the visible edges of a solar array. Unlike critter guards, skirts are primarily aesthetic, they hide exposed racking, rail ends, and the underside of panels.
When Panel Skirts Make Sense
For roofs visible from the street or backyard, skirts make a noticeable difference in appearance. They give the system a finished, integrated look rather than an “added on” appearance.
Skirts can also make edges less inviting to birds and debris accumulation, though they’re not a substitute for critter guards if wildlife protection is the goal.
When to Skip Skirts
If your panels aren’t visible from common angles, rear-facing roofs, steep pitches, or screened by trees, the aesthetic benefit may not justify the cost. Skirts are optional and driven primarily by personal preference.
Solar Insure and Extended Protection Plans
Solar equipment is built to last, but components do fail over decades of operation. Inverters are the most common replacement item, typically warranting service at the 10–15 year mark. Optimizers, wiring connections, and monitoring equipment can also require attention.
Manufacturer warranties cover specific equipment. Installer workmanship warranties cover installation-related issues for a defined period. What many homeowners want is additional protection for the long haul, after those initial warranties expire.
What Extended Protection Offers
Extended protection plans like Solar Insure provide:
- Long-term equipment coverage beyond manufacturer warranties
- Labor coverage for repairs and replacements
- Active monitoring that alerts you to production drops
- Predictable costs instead of unexpected repair bills
Monitoring is especially valuable. A system can underperform for weeks without obvious signs if no one is watching the data. Early detection prevents extended downtime and lost savings.
Who Benefits Most
Extended coverage appeals to homeowners who want predictable ownership costs and proactive oversight. It’s not required, but for long-term peace of mind, especially if you plan to stay in your home for 15+ years, it provides meaningful value.
Bundling Solar With Roof, Gutter, and Siding Upgrades
Solar installation is a natural time to evaluate related exterior work. Coordinating multiple projects under one timeline reduces disruption and often reduces total cost.
Roof Condition Comes First
Solar panels are designed to stay in place for 25+ years. Your roof should be able to match that lifespan.
Installing solar on a roof that needs replacement in 10 years almost always leads to additional cost later, panels must be removed and reinstalled, typically at $2,000–$5,000 or more.
Signs a roof should be replaced before solar:
- Shingles nearing end-of-life (15–20 years for asphalt)
- Repeated leaks or soft spots
- Curling, cracking, or granule loss
- Sagging or uneven rooflines
Replacing the roof first avoids future downtime and eliminates remove-and-reinstall costs. Coordinating both projects simplifies responsibility and scheduling.

Gutters and Water Management
Gutters play a quiet but important role in protecting roof edges and fascia. Poor drainage can cause water to pool near mounting points or create ice dams in winter.
Solar installation is a good time to assess gutter condition. Sagging sections, leaking seams, frequent clogs, or water spilling over during storms are signs an upgrade may be worthwhile.
Siding and Exterior Efficiency
Some homeowners choose to bundle siding work with solar, not because it’s required, but because exterior upgrades are already planned.
New siding can improve moisture control, reduce air leakage, and enhance insulation. When paired with solar, the result is a home that both uses less energy and produces more of its own.
Choosing the Right Add-Ons for Your Home
Not every home needs every add-on. We recommend options based on your roof, your surroundings and how long you plan to own the home.
High-value choices for most homes:
- Critter guards, essential for homes near trees or wildlife
- Roof assessment/replacement, critical if remaining roof life is limited
- Extended monitoring, valuable for long-term owners who want oversight
Situation-dependent:
- Panel skirts, worthwhile for highly visible installations
- Gutter upgrades, recommended if current gutters are failing
- Siding work, only if already planned or efficiency is a priority
A good solar plan accounts for how the system will perform and how it will look several years in, not just on installation day.

Frequently Asked Questions
Do critter guards affect solar panel performance?
No. Critter guards are designed to block animals from nesting beneath panels without affecting airflow, sunlight exposure, or panel efficiency.
Are solar panel skirts necessary?
Panel skirts are optional and primarily improve visual appearance. They’re recommended for highly visible roofs where aesthetics matter but aren’t required for system performance.
Is extended solar coverage like Solar Insure worth it?
Extended protection is optional but valuable for homeowners who want long-term monitoring, labor coverage, and predictable maintenance costs beyond manufacturer and installer warranty periods.
Should I replace my roof before installing solar?
If your roof has less than 10–15 years of remaining life, replacement before solar installation is usually the smarter financial decision. This avoids future panel removal and reinstallation costs of $2,000–$5,000 or more.
Can solar add-ons be installed later?
Some add-ons like critter guards can be retrofitted, but installation is typically easier and more cost-effective when done during the initial solar project.
How much do critter guards cost?
Critter guards typically cost a few hundred dollars when installed with your solar system. This is significantly less than the $1,000–$3,000+ cost of repairing squirrel damage to wiring and components.
