Why Birds Are Nesting Under Solar Panels This Spring – And How to Protect Both Your System and Local Wildlife
As spring unfolds across Germany, the skies are filled with birds returning, singing, and—most importantly—nesting. It’s a beautiful part of the natural cycle, but for solar panel owners, it can also present a major issue: birds nesting under solar panels. This may seem like a minor headache, but nesting can lead to serious problems for your solar panel's efficiency and longevity.
At the same time, it’s important to highlight: not all bird deterrent solutions are safe. Netting and mesh can trap birds, spikes can injure them, and brushes often block airflow or simply don’t last. That’s why we recommend BirdBlocker—a humane, effective, and long-lasting way to prevent nesting without harming our feathered friends.
The Breeding Season in Germany: A Busy Time for Birds—and Your Solar Panels
Between March and July, birds in Germany are in full breeding mode. Species like the House Sparrow, Common Starling, Jackdaw, and Feral Pigeon are all actively looking for warm, sheltered spaces to nest.
Unfortunately, solar panels offer exactly that:
- A dry, warm, and protected area
- Close to food sources (insects, seeds, human settlements)
- Often undisturbed, especially on rooftops
But while it may seem like a cozy nesting spot, this setup isn't safe for the birds. Trapped heat and excess temperatures as the season progresses pose a serious threat to them—and to your system. Spring and summer see the most sunlight hours, making it even more critical to protect your solar panels' efficiency from nesting birds.
Why Letting Birds Nest Under Panels Is Risky—and Can be Legally Complex
Once a nest is active—meaning eggs have been laid—removing it becomes legally restricted under German wildlife protection laws (Bundesnaturschutzgesetz). Interfering with an active nest could result in penalties and is, above all, unethical.
Beyond legal concerns, nesting birds can:
- Damage wiring, panels, and roof
- Cause overheating or reduced efficiency
- Lead to fire risks from nesting materials
- Create ongoing noise and mess, especially from droppings and debris
Blocking birds from nesting under your solar panel likewise encourages them to choose other spots like trees and shrubs. Prevention is key. And that’s where BirdBlocker comes in.
