Solar panels are a common sight across Massachusetts, but so are the critters that try to nest beneath them. As homeowners become more aware of the damage animals can cause, one question comes up again and again:
How many types of solar panel critter guards are actually used in Massachusetts, and which ones work best here?
The answer is not one-size-fits-all. Different guard types exist because Massachusetts homes face a mix of squirrels, pigeons, harsh winters, and strict wildlife protection rules that prioritize prevention over removal.
This blog breaks down the main types of solar panel critter guards used in Massachusetts, what problems each one solves, and what homeowners should know before choosing.
Type 1: Wire Mesh Critter Guards
Wire mesh guards are the most commonly used option across Massachusetts.
They are typically made from:
- galvanized steel
- PVC-coated steel
- heavy-duty metal mesh
These guards wrap around the perimeter of the solar panels, sealing the gap between the panel and the roof.
Why they’re popular in Massachusetts
- effective against squirrels and birds
- withstand snow and ice buildup
- allow airflow and drainage
- comply with Massachusetts wildlife rules by preventing access without harming animals
Homeowners often learn how this type works through resources like How Do Critter Guards Protect Your Solar Panels?
Type 2: Expanded Metal Panel Guards
Expanded metal guards use solid sheets of perforated metal rather than flexible mesh.
They are commonly used when:
- homes experience repeated squirrel pressure
- larger birds nest aggressively
- additional rigidity is needed
Massachusetts Specific Advantage
Expanded metal holds its shape well during freeze-thaw cycles, making it useful in areas with heavy winter weather.
However, installation quality matters. Improper spacing can leave gaps, which is why professional installation is often recommended.
Type 3: Bird Mesh Systems
Bird mesh is designed specifically to block birds, especially pigeons, from nesting under solar panels.
These systems are lighter than expanded metal and work well in:
- urban areas
- coastal towns
- Neighborhoods with heavy pigeon activity
While bird mesh is effective against birds, it is not always strong enough for squirrels. Many homeowners discover this after reviewing signs discussed in Top Signs You Need a Critter Guard for Your Solar Panels.
This is why bird mesh alone is sometimes paired with stronger materials.
Type 4: Custom-Fitted Hybrid Guards
Hybrid systems combine different materials, such as:
- wire mesh with reinforced edges
- mesh plus solid corner panels
- bird deterrent features with perimeter sealing
These setups are often used on:
- complex roof designs
- older Massachusetts homes
- large or irregular solar arrays
Hybrid systems are popular because Massachusetts homes vary widely in architecture, and critters quickly exploit weak points.
Type 5: Temporary or DIY Guard Solutions
Some homeowners attempt temporary solutions using:
- lightweight mesh
- plastic barriers
- zip-tied fencing
While legal, these options often fail within a season due to:
- snow load
- animal chewing
- wind movement
This leads many homeowners to later explore professionally installed critter guard solar panels in Massachusetts after repeat issues. The long-term difference is outlined in What’s the Difference Between Professional and DIY Critter Guard Installation?
Are All Guard Types Legal in Massachusetts?
Massachusetts laws do not restrict the type of critter guard material used. The key requirement is humane prevention.
This means:
- guards must block access, not trap animals
- active nests must be handled carefully
- prevention is preferred over removal
All the guard types discussed above are legal when installed correctly and used as exclusion barriers.
Which Type Is Most Common in Massachusetts?
Across Massachusetts, the most widely used systems are:
- wire mesh critter guards
- expanded metal guards for high-pressure areas
- hybrid systems for complex rooftops
These options provide reliable protection against the animals most likely to damage solar systems in the state.
