The Aviation Invasion: Why You Should Bird Proof Your Solar Panels

In previous blogs, we have mentioned the endless benefits of solar panels and their ability to reduce your energy bills and help the planet. However, there is another group feeling the benefits of the rising use of solar panels. From pigeons and seagulls to doves and sparrows, our feathered friends are quickly turning into foe as they live under and around our solar panels rent-free. They are the worst possible tenants you could be so unfortunate to have. 

But why do birds find solar panels so appealing? 

The elevated position of the panels gives birds an excellent birds-eye-view to keep an eye on their surroundings for any potential predators and food. The cosy and protected sheltered space under the panels is also the perfect, warm nesting area for birds. All of these elements combined make solar panels a prime real estate opportunity for birds.

How Birds Can Damage Your Solar Panels

While birds may enjoy this new habitat, your solar panels certainly will not. While bird droppings may provide luck for some, if it accumulates on the panel surfaces, your solar system won’t be so lucky. Excessive bird droppings leads to reduced energy efficiency and permanent discoloration and damage.

But the problems don't stop there. Nesting materials, such as twigs and leaves can disrupt airflow and block sunlight from reaching the panels, greatly reducing their power output. As well as this, birds’ incessant pecking and scratching can damage the wiring and electrical components of your panels, potentially leading to short circuits and other malfunctions.

All of these issues together lead to sky-rocketing maintenance costs for yourself as you will need your panels cleaned and checked over more frequently. Therefore, the long-term cost savings provided by solar panels may not seem so appealing after all.

The Case for Bird Proofing

After seeing the multitude of ways birds can risk the performance and longevity of your solar panels, bird proofing them seems like a no-brainer.

Increase Energy Efficiency

By preventing birds from nesting or leaving their droppings on the panel surfaces, you can maintain maximum exposure to sunlight.

Cost Savings 

The essential factor of well-functioning solar panels? Regular maintenance and cleaning. However, this can feel like a losing battle (as well as an expensive one!) when you are having to compete with bird droppings and nesting materials. With efficient deterrents, you can relax and enjoy the benefits of your solar panels, without the need for extensive maintenance.

Protecting Birds and the Environment

Not only is this new habitat a risk to your solar panels, it can also be deadly for birds. They can become trapped, injured or even killed if they come into contact with the electrical components or if they become entangled in the panels. Maintain the eco-friendly nature of your solar panels by protecting birds from the dangers of them. 

Longer Lifespan of Your Solar Panels

The corrosive nature of bird droppings and the physical damage caused by nesting materials can significantly shorten the lifespan of your solar panels. Inject your solar panels with a new burst of life by bird proofing them.

What Does Bird Proofing Look Like 

When it comes to protecting your solar panels, there are several proven strategies and products available. 

Solar Panel Mesh

Solar panel mesh provides a physical barrier between birds and solar panels and is carefully fitted around the edges of your solar panels, so no birds can access your panels. 

Bird Spikes

Alongside the solar panel mesh, bird spikes make it uncomfortable for birds to land or nest on the solar system, meaning they will have to look elsewhere to find their perfect home.

Cleaning and Maintenance

The most common way to protect your solar panels is through regular cleaning and maintenance. By evicting the birds through removing their nest and droppings, you will discourage them from returning.
