How do photovoltaic power plants drive birds away?
The power generation principle of photovoltaic power station is that sunlight irradiates photovoltaic modules to generate photovoltaic effect, and then generates electricity. However, the shading problem caused by dust and bird droppings on the surface of photovoltaic modules prevents sunlight from reaching the light intensity of photovoltaic cells to a certain extent. Therefore, the cleaning problem of the surface of photovoltaic modules directly affects the power generation efficiency of photovoltaic power plants.
The dust on the surface of the module is easy to clean, but the bird droppings are not so simple: because the bird droppings are viscous and difficult to clean, the complex composition can easily cause chemical corrosion to the glass of the module, and the opacity causes the module to block. In light of this, the power generation efficiency of the modules will be affected, while in the worst cases, hot spots will be formed or even cause the modules to catch fire, and frequent cleaning of bird droppings will scratch the surface glass of the modules, which will also greatly reduce the power generation of the power station. Therefore, it is necessary to find a tool to drive birds away in photovoltaic power plants.
Bird repelling method one
Add thin wire or fishing line
Add a device as shown in the figure below to the module array or bracket, and the height is about 5 cm from the module frame. When the bird flies directly above the module, make sure that the bird cannot stand on the module frame and the thin wire, and it is affected by the wind. Influence, the steel wire rope or fishing line will resonate due to the wind blowing, making a humming sound, which plays a role in assisting bird repelling.
Bird repelling method 2
Add wind bird repellent
The bird repeller uses wind as the power source, and adopts a unique bearing, and installs a lens on the wind wheel, so that the wind wheel uses the principle of optical reflection to form an astigmatism area in the bird repellent area during repeated motion, so that the birds They are afraid of light and dare not approach nesting and perching.
The bird repellent is completely made of insulating material, which is corrosion-resistant, has good toughness and is not easy to break, and can be started with a slight wind. 360 degree reflection angle, no driving blind spots. The reflector frame of this product is designed in a bowl shape to supplement the power and increase the power and speed of the bird repelling device's rotation; the rotating shaft is designed with a damping coefficient, which has the effect of resisting typhoons, will not rotate infinitely, and is safe and reliable. The product is easy to install, maintenance-free, and has a lifespan of up to 8 years. Passive wind energy, clean and environmentally friendly.
Three ways to drive birds
Adding lasers to component arrays
+ Directional Sonic Bird Repeller
The laser bird repelling system uses the physical characteristics of the laser to emit a green laser beam with a diameter of 20mm (can be customized according to the required size) and a wavelength of 532nm to scan the birds. This laser beam has obvious stimulation to the bird's vision. , like a green stick that is dialed back and forth, and the frightened bird will stay out of range.
Experiments have shown that birds will never have memory and adaptability to this driving method, thus ensuring that long-term use will not fail. Especially for nocturnal birds, traditional methods are often ineffective, but the use of laser bird repelling technology highlights the night bird repelling effect, filling the gap in the airport's night bird prevention work.
Laser light source, wavelength 532nm, power 1000mw, output by optical beam expansion technology equipment to achieve safe laser, laser level 2M. Optical lens group realizes parallel beam, beam angle: 0.05mr, 100% will not cause harm to personnel, laser bird repelling system, sealing grade IP55 with built-in temperature control system. Lightning protection, radiation protection, no interference to other electronic equipment.
The above three ways of repelling birds are the most used, and it is not ruled out that there are more ways to achieve the goal. In the case of not breaking the ecological balance, it is guaranteed that the photovoltaic power station can have a greater output power.
