The Importance of Solar Critter Guards for Home Solar Systems


When homeowners decide to install a solar energy system, they often overlook a crucial aspect of the installation process – protecting their investment from critters and environmental debris. Critter guards, also known as solar screens or strips of metal screening, play a vital role in safeguarding solar panels from potential damage caused by birds, squirrels, roof rats, and storm debris. In this article, we will delve into the benefits of installing solar critter guards and why they are essential for the longevity and performance of home solar systems.

Protecting Against Critters and Debris

Solar panels installed on rooftops are exposed to various threats, including hail, lightning strikes, fallen tree branches, wind-blown debris, and even wildlife. Critters like squirrels and roof rats can wreak havoc on solar systems by chewing on wires, nesting under panels, and causing malfunctions. Birds, such as pigeons and doves, may also nest on and under solar panels, leading to excessive dirt, debris, and droppings accumulation, which can significantly reduce panel efficiency. Additionally, storm debris, such as tree branches and leaves, can build up under panels, posing a fire hazard near electrical wiring.

Understanding Critter Guards

Critter guards act as a physical barrier between solar panels and potential intruders. These strips of metal screening, similar to high-quality chicken wire, are installed along the sides of rooftop or ground-level solar panels. They effectively block birds, squirrels, roof rats, and other critters from accessing the space beneath and between the panels. Critter guards also prevent twigs and debris from accumulating, reducing the risk of fire hazards.

The Benefits of Solar Critter Guards

1. Protection Against Wildlife Damage

One of the primary benefits of installing solar critter guards is the prevention of damage caused by wildlife. Birds, in search of shade, often nest under solar panels, which can lead to panel soiling and reduced efficiency. Squirrels and roof rats are notorious for chewing on wires, potentially causing electrical malfunctions and system downtime. Critter guards act as a deterrent, keeping these animals at bay and protecting the integrity of the solar system.

2. Minimized Fire Hazards

Critter guards not only protect against wildlife damage but also minimize fire hazards. Debris, such as tree branches and leaves, can accumulate under solar panels and pose a significant risk if in contact with electrical wiring. By preventing debris buildup, critter guards reduce the chances of a fire starting near the panels, providing homeowners with peace of mind.

3. Enhanced Panel Efficiency

When birds nest under solar panels, their droppings can accumulate and block sunlight from reaching the panels’ surface. This buildup reduces the system’s overall efficiency and energy production. By installing critter guards, homeowners can prevent excessive dirt, debris, and droppings accumulation, ensuring optimal panel performance and maximum energy generation.

4. Extended Lifespan of Solar Panels

Solar panels are a long-term investment, often lasting 25 years or more. Protecting them with critter guards can significantly extend their lifespan by shielding them from potential damage. By minimizing the risk of chewed wires, nesting animals, and debris buildup, critter guards help maintain the structural integrity of the panels, ensuring they continue to operate efficiently for many years.

5. Cost Savings on Repairs and Maintenance

Solar critter guards can save homeowners money in the long run by reducing the need for repairs and maintenance. Damaged wires, chewed by critters, can lead to electrical malfunctions, requiring costly repairs. Additionally, excessive debris buildup may require professional cleaning services to restore panel efficiency. By investing in critter guards, homeowners can avoid these additional expenses, making their solar system more cost-effective in the long term.

Proper Installation of Critter Guards

To reap the full benefits of solar critter guards, it is crucial to ensure their proper installation. Hiring experienced solar professionals, such as Seed Solar, can guarantee a secure and effective installation process. By attaching the critter guards correctly, the integrity of the roof and solar panels can be maintained without compromising the system’s performance. Seed Solar’s experts take pride in their meticulous installation methods, offering homeowners peace of mind and confidence in their solar investment.


Solar critter guards are a crucial component of every home solar system.
