Photovoltaic sound barriers on highways are installed on both sides of traffic roads. They are combined with traditional sound barriers to generate electricity while reducing noise. Photovoltaic solar energy is a clean energy source. Using it can greatly reduce carbon emissions and has the effect of energy conservation and emission reduction. Photovoltaic sound barriers are very environmentally friendly and effective, and are more conducive to sustainable development. Features: 1. Large sound insulation (>30dB); 2. Good weather resistance; 3. High strength; 4. Combined noise reduction and power generation; Application: high-speed railways, urban rail transit, viaducts and other traffic road places;
