Do Solar Panels Attract Birds? And why it happens

Unlike trees that move around in the wind and get exposed to weather, the area underneath solar panels stays relatively protected all year round.

From our experience working on bird proofing jobs across Brisbane, we’ve repeatedly seen pigeons choosing solar systems because the nesting area remains sheltered and consistent. Unlike a tree branch that can move, break or become exposed during storms, the gap under the panels stays much the same year after year.

This is one reason many Brisbane homeowners eventually install solar panel bird proofing once pigeons become established underneath the panels.

Why Pigeons Keep Coming Back

One of the biggest reasons pigeon problems grow over time is because pigeons are extremely location-oriented.

Once they successfully nest somewhere, they usually remember that location and return during future nesting cycles.

We’ve seen many situations where:

• Pigeons nested under the panels once

• Temporarily disappeared

• Homeowners thought the problem was solved

• The same pigeons returned months later

• More pigeons arrived with them

Over time, the nesting area becomes:

• Larger

• Dirtier

• More established

• Harder to clean

Many homeowners describe it as if the problem suddenly exploded, but in reality, the birds have usually been returning repeatedly over time.

This behaviour is explained further in How Long Do Pigeons Stay Under Solar Panels?

Do Solar Panels Attract Certain Types Of Birds?

While pigeons are by far the most common birds we see nesting under solar panels, they are not the only ones.

Every now and then we also encounter:

• Small native birds

• Mynas

• Sparrows

• Possums seeking shelter

However, pigeons are by far the biggest issue because they:

• Nest in groups

• Return repeatedly

• Produce large amounts of droppings

• Expand nests over time

This is why most bird proofing work is specifically focused on preventing pigeons from accessing the space underneath the panels.

Do Certain Homes Attract More Birds?

From what we’ve seen throughout Brisbane, pigeons don’t seem to care much about:

• Roof material

• Tile roofs versus Colorbond roofs

• Solar panel brands

• Roof colour

As long as there is a gap underneath the panels, they are usually happy.

One interesting observation we’ve noticed is that double-storey homes often seem more attractive than lower homes nearby.

For example, if there is a street with mostly single-storey homes and one taller home in the middle, pigeons often appear to favour the higher roofline.

It’s not a rule, and we still bird proof plenty of single-storey homes, but higher roofs do seem to attract more activity in many situations.

Sometimes The Birds Come From Nearby Homes

A lot of homeowners are surprised when they suddenly develop a pigeon problem despite never seeing one before.

What often happens is:

• A neighbour installs bird proofing

• The pigeons lose access to that roof

• The birds start looking for a new nesting location

• They move to nearby homes with open access underneath the panels

We’ve seen this happen many times.

One property gets professionally bird proofed, and within months another nearby property starts seeing increased pigeon activity.

That’s one reason prevention is usually easier than waiting for a nesting problem to develop.

Many homeowners choose bird proofing before a major nesting problem starts.

How Can You Tell If Birds Are Nesting Under Your Solar Panels?

A lot of people assume pigeons sitting on the roof is normal.

And sometimes it is.

But the important thing is recognising patterns.

If you notice:

• Pigeons on the roof every day

• Birds constantly flying in and out

• Early morning cooing and scratching

• Droppings around the panels

• Nesting material in gutters

• Large clumps visible underneath the panels

Then there’s a good chance birds are already nesting there.

One simple trick for double-storey homes is to walk further down the street and look back towards the roof. Often you can see the gap underneath the panels. If light is blocked by large clumps of nesting material, that’s often a clear sign of a nest.

We explain this process in more detail in How To Tell If Birds Are Nesting Under Your Solar Panels.

What Problems Can Birds Cause Under Solar Panels?

At first, the issue often seems like a minor annoyance.

A few birds.

A bit of noise.

Some droppings.

But over time, nesting underneath solar panels can create much bigger problems.

We’ve personally seen:

Blocked Gutters And Downpipes

Nesting material and droppings wash into gutters and create blockages.

Roof Damage

On metal roofs, bird droppings and constant activity can contribute to paint deterioration, scratches and corrosion.

Loose Electrical Cables

We’ve seen situations where years of nesting activity caused cables underneath the panels to become displaced or loose.

Fire Hazards

Large amounts of dry nesting material can build up underneath the panels where heat and electrical components are present.

Bird Lice

Some homeowners report bird lice entering roof spaces and living areas after long-term nesting problems.

Reduced Solar Performance

Dirty panels and restricted airflow can contribute to lower system performance over time.

Why DIY Bird Deterrents Usually Fail

Before calling a professional, many homeowners try DIY deterrents.

We’ve seen people use:

• Fake snakes

• Plastic owls

• Reflective tape

• CDs hanging from roofs

• Noise machines

• Vinegar sprays

• Plastic mesh

Sometimes these methods work briefly.

But once pigeons have already nested underneath the panels, they usually become very determined to stay.

Eventually they realise:

• The owl never moves

• The snake isn’t real

• The sound isn’t dangerous

• The smell disappears after rain

And they simply continue nesting.

We discuss these methods further in How To Stop Pigeons On Solar Panels: Best Solutions That Actually Work.

So, Do Solar Panels Attract Birds?

Technically, no.

Solar panels do not attract birds by themselves.

What attracts birds is the protected nesting space underneath them.

To pigeons, that gap offers:

• Shelter

• Warmth

• Protection

• Stability

• A familiar nesting environment

And once they move in, they often keep returning until access is properly blocked.

Prevention Is Better Than Waiting

One thing we always tell homeowners is that prevention is almost always easier and cheaper than waiting.

Most nesting problems begin with:

• One or two birds

• A small nest

• Light roof activity

But over time, those small problems can turn into:

• Multiple nests

• Significant contamination

• Gutter blockages

• Roof damage

• Expensive clean-up work

If you suspect birds may already be using the space underneath your solar panels, it’s worth investigating early before the problem becomes established.
