Solar panels are one of the smartest investments for any home or business. They lower electricity bills, generate sustainable energy, and increase property value. But there’s a hidden problem that many overlook: birds nesting under solar panels.
The space between the panel and the roof is warm, dry, and safe from predators, making it the perfect spot for birds to build nests. The problem is that this not only affects the birds but can also cause serious damage to the system, loss of efficiency, and even fire hazards. That’s why bird protection is not a luxury but a necessity.
Why do birds nest under solar panels?
During spring, in the breeding season, the gap under the panels offers an ideal refuge. However, in summer, temperatures under the panels can exceed 70 °C (158 °F), becoming a deadly trap: eggs may “cook” and chicks rarely survive.
Even if the adults escape, nesting debris remains and attracts more birds in the following seasons, creating a cycle of dirt and problems year after year.
Main risks of bird nests under solar panels
Fire hazard and electrical damage
Twigs, leaves, and dry grass used in nests are highly flammable materials. If they come into contact with damaged or overheated cables, they can cause a short circuit and, in the worst case, a fire. In addition, bird droppings contain acids that corrode cable insulation and connectors, further increasing the risk.
Loss of efficiency
Nests block natural ventilation under the panels, raising temperatures and reducing energy output. This also accelerates the appearance of hotspots, which shorten the lifespan of the panels.
Dirt, odors, and noise
Droppings dirty the panels and block sunlight, reducing energy production by several percentage points. At the same time, birds cause constant noise, and nesting debris produces unpleasant odors, especially in summer.
Pests and hygiene problems
Nests are also a source of mites, fleas, or ticks that may enter homes or nearby buildings. This is a particularly serious risk in farms, hospitals, schools, or food industries.
Prevention is the best solution
Removing nests or repairing damage once it occurs can be expensive and complicated. In addition, solar panel warranties and many insurance policies do not cover bird-related damage, as they are considered external factors. That’s why the best strategy is prevention: stop birds from accessing the space under solar panels in the first place.
BirdBlocker: the effective and lasting solution
The BirdBlocker system is designed to seal the gap between panels and roof using HDPE strips with upright spikes. This way, birds cannot enter or nest, but natural ventilation of the panels remains intact.
- Available in two models: BB125 and BB200, depending on the installation height.
- Material: black HDPE, UV-resistant and 100% recyclable.
- Includes stainless steel clips for quick and secure installation.
- No screws or drilling: does not affect panel warranty.
- 10-year material warranty.
With BirdBlocker you protect your panels, avoid damage, and extend the lifespan of the installation—all with minimal visual impact and respect for the environment.
Conclusion
Protecting solar panels from birds is an essential step to guarantee their efficiency and safety. Damage from nests is completely preventable if proactive measures are taken from the start.
