Why Do Birds & Squirrels Nest Under Solar Panels?

Before moving ahead with all the solutions on how to bird-proof & squirrel-proof your solar panels, let’s first understand why these creatures creep in or around the solar panels.

Protection – Small birds & squirrels often face difficulty in facing predators or bigger creatures than them. Solar panels provide them a safe haven and a feeling of safety from such unwanted lookers.

Easy Access – The gaps between the roof and panels or, ground and panels is ideal for small birds or animals to slip in without much effort and build a comfy home!!

Of course it’s a noble thought, but your solar panels might not be solution to their problems.

Best Ways to Keep Birds & Squirrels Away from Solar Panels

Install Solar Panel Critter Guards or Wire Mesh

A critter guard is a wired mesh kind of thing which can help unwanted creatures off of your solar panels and will also prevent tree leaves and flowers from rolling under your solar panels.

  • How It Works – Critter guards create a strong physical barrier, preventing birds and squirrels from entering the space beneath your panels.
  • Best material for Critter Guards – Stainless Steel or coated wire mesh is the best option in critter guards. It is strong, durable and works in all seasons.
  • Cost – Professional installation can cost anywhere between $50-$100 depending upon the material and the size of panels. Although it’s not much a task, so you can get a DIY kit for almost half the price.
  • DIY Tip – If you like DIY, one option is to buy a simple net/ cloth from a local hardware shop and zip-tie it firmly around the panels.

Use Anti-Bird Spikes to Keep Birds & Squirrels Away from Solar Panels

Anti-Bird spikes might look a bit dangerous from a bird’s point of view but it might also be the best solution out there against them. Also the spikes need not be very pointy so that a bird might not get hurt due to them. The birds do not come anywhere near if they notice the spikes. This will prevent a lot of time & energy of the owner.

  • How It Works – Spikes make it uneasy for birds to land and sit at one place.
  • Installation – Generally spikes come with a sticky base. So you just have to peel off the sticker from beneath and stick it firmly around the edges of your panels. Those spikes which do not come with a sticky base, you can zip tie them instead of sticking.
  • Cost – $3-$20 per meter.
  • Pro Tip – Apply spikes on nearby fences, pipes, or edges where birds gather before moving to your roof.

Ultrasonic Repellents (Sound-Based Deterrents)

If you did not like the first two solutions and prefer a hassle free methodology, this one’s for you.

  • Ultrasonic insect & birds repellent devices emit high-frequency sound waves that can irritate the birds and the birds and many other pests might not wander near your house. The best part of such repellents is that they are completely inaudible to the humans. So you don’t have to worry about the sound it emits.
  • Installation – Just place it anywhere on your roof or in garden or near your panels.
  • Pros – Birds and many other insects and creatures might stay away from your home.
  • Cons – A bit costly, needs electricity or battery, cannot survive much in open (since its electronic it might get damaged due to heat, dust or water)
  • WARNING – Some animals may adapt to the sound over time, so mix this method with others.

Reflective & Scare Tactics (DIY Solutions!)

This is my favorite option… DIY!!
Try these simple tricks before going for above mentioned methods

  • CDs & Aluminum Foil – Hang old or unwanted CDs (Compact Discs) or Aluminium foil strips near or around the solar panels. The light reflected from these scares the birds a lot and they do not dare to come anywhere near these objects.
  • Fake Snakes & Owls – You can also try placing dummy snakes or owls near the panels. Birds notice these predators from far off and might not come near your panels.
  • Anything that makes noise or reflects sunlight will also work. It’s DIY so you have to try few permutations & combinations.
  • Quick Tip: Change the position of decoys every few days so birds don’t get used to them.

Apply Non-Toxic Bird Repellent Gel

If your panels are not disturbed by birds frequently and also no other small animal comes near your panels then you might not want to take the hassle for installing the mesh or the spikes or the repellent device. Then this option might work for you…

Apply a bird repellent gel. Such gels are thick and sticky yet transparent.

Most of the birds dislike the sticky sensation and odor of the repellent and will avoid coming near the panels. This is very safe for birds, easy for you and cost effective. But the cost part mostly depends on number of panels you have.

  • Approximate Cost – $5-$30 per tube.

Trim Nearby Trees & Seal Entry Points

Birds and other animals like the squirrels often use trees to access your roof. Trimming overhanging branches can help. Also find and seal any small gaps or holes on your roof where animals might sneak in.

  • Tip: Check your attic for signs of squirrels before they become a bigger problem.

Professional Bird & Pest Control Services

If you have a serious infestation problem due to birds or any other animal, it’s best to take help from a pest control expert. They can safely remove nests and apply long-term solutions. Look for experts who specialize in solar panel protection so they don’t damage your system.
