Black plastic-coated welding net: an efficient bird-proof scheme to protect the safety and efficiency of solar panels

the pain point of the industry: the threat of birds to solar power plants

With the popularization of photovoltaic power generation, the scale of solar power stations is expanding, but bird activities have become a difficult problem in operation and maintenance:

• Nesting hazard: Birds nest under solar panels or on supports, which blocks sunlight and reduces power generation efficiency (the efficiency loss of a single panel can reach 15%-30%).
• Fecal corrosion: Bird droppings contain acidic substances, which will corrode the surface coating of photovoltaic panels for a long time and shorten the service life.
• Line damage: Birds peck at cables or junction boxes, leading to short circuit and even fire risk.
• Traditional bird prevention measures (such as reflective tape and ultrasonic bird repeller) have limited effect, while black plastic-coated welded mesh has become the preferred scheme in the industry because of its durability and concealment.

the core advantages of black plastic-coated welded wire mesh

1. Efficient physical barrier and long-term bird prevention.

Tight mesh design: The mesh size is usually 2.5cm×2.5cm or 5cm×5cm, which not only prevents birds from getting in, but also avoids affecting ventilation and heat dissipation.
High-strength material: high-quality low-carbon steel wire welded, with tensile strength ≥500MPa, which can withstand strong wind and large bird impact.

2. Black plastic coating technology, double protection

Anti-corrosion: PVC or PE coating (thickness 0.2~0.5mm) on the surface is acid and alkali resistant, anti-ultraviolet and suitable for outdoor harsh environment (life is more than 10 years).
Concealment: The black coating and the color of the solar panel frame are combined to reduce visual pollution and keep the power station beautiful.

3. Convenient installation, economical and practical.

Modular design: it can be cut into sheets or rolls and fixed directly on the bracket or frame without complicated tools.
Cost advantage: the unit price is about 15 ~ 30/㎡, which is only 1/3 of the custom-made metal bird thorn prevention, and the maintenance cost is extremely low.

Typical application scenarios

• Large ground photovoltaic power station

Case: After the installation of plastic-coated welded wire mesh in 100MW power station, the bird activity decreased by 90% and the annual power generation loss decreased by 8%.

• Distributed roof photovoltaic

Solve the nesting problem of pigeons and sparrows on civil roofs and avoid frequent cleaning costs.

• Agro-optic complementary project

The WELD WIRE mesh allows sunlight to pass through without affecting the growth of crops below, achieving a win-win situation of "power generation+bird prevention".

Installation and maintenance guide

• Installation step

Measurement and cutting: 5cm margin is reserved according to the size of solar panel array.

• Fixed mode:

Bracket fixing: Tie the mesh to the bracket beam with stainless steel tie or bolt.
Frame fixing: connect with the plate frame through buckles or U-shaped nails (avoid direct contact with the plate surface).

• Precautions: keep the net surface flat to prevent sagging and dust accumulation.

Market Prospects and Policy Support

• Demand growth: The global installed capacity of photovoltaic is expected to reach 5TW in 2030, and the annual growth rate of the bird-proof network market exceeds 12% (data source: IEA).
• Policy promotion: China's Code for Operation and Maintenance of Photovoltaic Power Stations clearly requires "taking effective measures to prevent bird harm", and the plastic-coated welding net conforms to environmental protection standards.

Choose the key indicators of quality products

Material: Q195 or Q235 steel wire, galvanized layer ≥60g/㎡ (base material is rustproof).
Coating: PVC/PE raw materials need to pass environmental protection test, and there is no heavy metal precipitation.
Certification: ISO 9001 certification are available to ensure outdoor durability.

Black plastic-coated welding WIRE MESH has become an ideal choice for bird prevention in solar power stations because of its high cost performance, long-term protection and beautiful and practical characteristics. Photovoltaic owners and EPC manufacturers can further reduce the cost through large-scale procurement (such as customizing the batch size of 10km) and realize efficient operation and maintenance of the whole life cycle of the power station.
