Effective Bird Proofing Solutions

Without proper measures, birds can cause significant damage to your solar panels. Let's explore why bird proofing matters and how it benefits solar panel owners.

1. Bird Mesh Wire

Mesh barriers block birds from accessing certain areas. They are handy for protecting large open spaces like gardens, rooftops, and solar panels. The mesh is usually made from durable materials like polyethylene or stainless steel, ensuring long-lasting protection.

Specialised mesh or barriers designed for solar installations can prevent bird access without compromising panel efficiency.

Pros:

  • Highly effective at preventing birds from entering protected areas.
  • Durable and weather-resistant.
  • It can be customised to fit various spaces.

Cons:

  • It can be expensive to install over large areas.
  • It may require regular maintenance to ensure there are no gaps or damage.

2. Bird Spikes

Bird spikes are strips of spikes that can be attached to ledges, rooftops, and other surfaces where birds like to perch. The spikes make it uncomfortable for birds to land, thus deterring them from the area.

Durability and Effectiveness: Bird spikes are highly durable, often made from stainless steel or UV-resistant plastic. They are effective against larger birds like pigeons and seagulls but may be less effective against smaller birds like sparrows.

3. Reflective Tape and Decoy Predators

Reflective tapes and decoy predators (like fake owls or hawks) create visual disturbances that scare birds away. These solutions are easy to install and inexpensive. However, birds can become accustomed to these deterrents, reducing their effectiveness.

4. Ultrasonic Devices

Ultrasonic devices emit high-frequency sounds that are supposed to deter birds. However, studies have shown that birds do not perceive ultrasound, making these devices largely ineffective for bird control.

5. Laser bird deterrent systems

Laser bird deterrent systems use green laser beams to create a visual threat that birds perceive as a physical danger. This makes them fly away and avoid the area. These systems can be manual or automatic, with the latter being programmable for different times and locations.

Recent studies demonstrate laser systems' remarkable efficacy. Research conducted at Wageningen University revealed a 98.2% reduction in wild bird visits to protected areas. 

The AVIX Autonomic Mark II laser system, in particular, showed impressive results. While initial costs for laser systems may exceed traditional methods, their long-term effectiveness and low maintenance requirements often result in cost savings over time.

Benefits:

  • Silent Operation: Lasers are quiet, unlike auditory deterrents, making them suitable for noise-sensitive areas.
  • Long-lasting Effectiveness: Birds are unused to the laser beams, ensuring continued effectiveness.
  • Environmentally Friendly: Lasers do not harm birds or the environment, making them a humane and eco-friendly solution.

6. Solar Skirt

A solar skirt is a specialised barrier that fits around the perimeter of solar panels. It prevents pigeons from nesting while allowing for proper ventilation. Solar skirts are often custom-made to fit specific panel sizes and shapes, ensuring a snug and practical fit.

7. Bird Blockers

Bird blockers are barriers that prevent pigeons from nesting under solar panels. These blockers are typically made from durable materials like stainless steel or plastic. They are designed to be installed around the edges of the panels, creating a physical barrier that pigeons cannot penetrate.
