Netting vs. Bird Spikes: Cost-Effective Bird Control for Solar Arrays

If you’ve invested in solar panels, you already know the value of clean, renewable energy. But what many homeowners and facility managers don’t realize is that birds nesting beneath solar arrays can quickly turn that investment into a maintenance headache. When it comes to bird control, two of the most common options are bird netting and bird spikes. Which one offers better long-term protection for your panels?

• The Problem: Birds and Solar Panels Don’t Mix
  Birds are drawn to the warm, sheltered space beneath solar panels. Nesting materials and droppings can damage wiring, clog drainage, and even become a fire hazard. Over time, this leads to reduced panel efficiency, higher cleaning costs, and potential warranty issues.
• What Are Bird Spikes?
  Bird spikes are rows of thin rods attached to ledges and rooflines to deter birds from landing. They’re a visual and physical deterrent, commonly made from stainless steel or plastic. While effective on flat surfaces, spikes are not ideal for the gaps beneath solar panels.
• What Is Bird Netting?
  Bird netting is a mesh barrier system installed around the perimeter of solar panels or building features. It physically blocks birds from accessing the underside of the panels or other nesting-prone areas. Netting can be made from UV-stabilized polyethylene or galvanized metal, and comes in various mesh sizes depending on bird species.
• Comparing Bird Netting vs. Bird Spike
  Bird spikes are ideal for small, narrow areas like ledges and ridges, but they offer only partial coverage and birds often adapt to them. Bird netting, by contrast, provides full perimeter protection under solar panels, completely blocking access. Netting is more discreet, typically lower maintenance, and lasts significantly longer—especially when UV-resistant materials are used. While spikes may be visible and require more frequent replacement, netting blends in and provides durable, long-term effectiveness.
• Cost-Effectiveness Over Time
  Bird spikes may seem like a cheaper option upfront, but because they don’t fully block access beneath solar panels, birds often find ways around them. Bird netting, while slightly more expensive, offers more comprehensive and longer-lasting protection, often reducing cleaning and repair costs over time.
• Ideal Use Cases
  Bird Spikes: Ledges, parapets, gutters, signage
  Bird Netting: Under solar panels, eaves, warehouse beams, HVAC units
• Our Recommendation
  For solar panel protection, bird netting is the clear winner. It fully prevents access and minimizes ongoing maintenance, making it the preferred choice for both residential and commercial installations.
