In recent years, the spread of solar panels has led to a sharp increase in damage caused by birds entering through the gaps between roofs and solar panels. The "Bird Blocker" firmly blocks bird entry by installing a mesh fence in the gap between the solar panels and the roof. 【Features】 ■ Easy installation! Compatible with solar panels from various manufacturers! Certified as a recommended product for SHARP panels! With a dedicated bracket (patent pending), the fence can be easily installed! The fence has a moderate hardness, making it easy to cut or bend for on-site adjustments. ■ Made entirely of stainless steel for high durability! Both the brackets and the fence are made of all stainless steel (SUS304), ensuring reliable Japanese quality! ■ Compatible with all types of roofs! By using three types of brackets in combination, the fence can be securely installed on uneven roofs, such as tiled roofs. ■ Maintains the warranty of solar panels!

The spread of solar power generation is progressing, with solar panels being installed on the roofs of various buildings, from ordinary households to corporate buildings and factories. Amidst this, there is an increasing problem of pigeon damage to solar power systems. One particularly serious issue is when pigeons get between the solar panels and the roof and build nests. If pigeon feathers, droppings, and nesting materials enter the solar power system, they can cause malfunctions. There is also a high possibility of noise damage caused by the pigeons moving around. Furthermore, if pigeons settle in, the droppings can escalate, and if the solar panels become dirty with a large amount of droppings, the power generation efficiency will decrease. To ensure that the solar power generation we have carefully introduced is not ruined by bird damage from pigeons, we want to take thorough measures against pigeons. Our "Bird Blocker" firmly blocks bird intrusion by installing a mesh fence and a specially patented fixture in the gap between the solar panels and the roof. *For more details, please refer to the PDF materials or feel free to contact us.

In recent years, the spread of solar panels has led to a sharp increase in damage caused by birds entering through the gaps between roofs and solar panels. When birds invade, they may nest under the solar panels, leading to issues such as droppings, noise, panel malfunctions, and decreased power generation efficiency. The "Bird Blocker" effectively blocks bird entry by installing a stainless steel mesh fence in the gap between the solar panels and the roof. Thanks to a special bracket (patented), the fence can be easily installed. The fence has a moderate hardness, making it easy to cut, bend, and adjust on-site. It can be installed during the installation of solar panels or on existing solar panels.
