Preventing Crows from Nesting Under Solar Panels: An Animal-Friendly, Sustainable Solution with BirdBlocker

Did you know that crows are a protected species in most of Europe? This raises many questions for solar panel owners about what they can and cannot do to prevent crows from nesting under their solar panels.

In this article, we’ll cover what’s allowed by law, why these clever birds get drawn to solar installations, and how the high-quality bird proofing BirdBlocker provides an animal-safe and sustainable solution for protecting your solar investment.

| Why Are Crows Attracted to Solar Panels?

Crows are highly adaptable and intelligent birds. The main species include the carrion crow, magpie, and rook, with the carrion crow being the most common around residential areas.

Although generally social, crows tend to nest alone or in small family groups during nesting season. This unique trait explains why a lone crow under your solar panels can quickly become a recurring issue.

The underside of solar panels provides many seemingly positive opportunities for nesting birds, namely:

• Shelter to build below
• Warmth during colder months
• Safety from predators

Though as the temperatures rise this safe space can become lethal (see section: Can Crow Deterrents Be Animal-Friendly?)

However, nests beneath solar panels lead to several significant issues. Bird droppings from crows build up with each flight, creating a layer of grime that blocks sunlight and drastically reduces the efficiency of your panels.

Over time, this buildup cuts energy output, negates your environmental efforts, and accelerates panel aging. Crows are also known to tamper with wiring; their natural curiosity and strong beaks can damage cables, increasing the risk of costly repairs and even potential fire hazards​.

| Do Crow Nests Reduce Solar Panel Efficiency?

Absolutely. Nesting materials not only trap heat beneath the panels but also restrict airflow.

Studies show that reduced ventilation under solar panels can raise temperatures by up to 20%, lowering efficiency by 10% or more during peak months. This trapped heat accelerates wear on the panels, decreasing long-term energy output and costing you financially.

Additionally, crow nests are built with dry, flammable materials like twigs and straw, which can lead to fire risks when combined with the rising temperatures under your solar array​

| Can Crow Deterrents Be Animal-Friendly?

Keeping crows out from under solar panels is not only legal but actually beneficial for bird welfare.

During summer months, temperatures beneath solar panels can exceed 70°C, effectively “cooking” any eggs or fledglings. When adult crows abandon these nests to escape the heat, they often return the following season.

By deterring crows from nesting under panels, you’re encouraging them to seek out safer, cooler habitats and reducing the likelihood of repeated nesting failures. 

| How BirdBlocker Protects Your Solar Installation and Bird Welfare

BirdBlocker offers an innovative and proven solution to keep crows and other birds from nesting under solar panels without harming them. This deterrent, known as a “bird strip,” is made from robust plastic and designed specifically to withstand the strength and curiosity of crows.

The product features upright plastic “fingers” that securely attach to the edges of your solar panels, creating a barrier that crows cannot bypass or damage. BirdBlocker is UV- and frost-resistant and comes with a 10-year product warranty, ensuring long-lasting protection.

When installed correctly, BirdBlocker effectively prevents birds from accessing the area under your solar panels while maintaining optimal ventilation to maximize solar efficiency. The product’s high-quality materials are 100% recyclable, contributing to sustainability efforts.

As a solar panel owner, using BirdBlocker enhances your panels’ lifespan and energy yield while also making an eco-friendly choice that respects local wildlife.
