Photovoltaic Noise Barrier

Product Introduction

Photovoltaic Noise Barrier is an integrated solution that combines effective noise reduction with solar power generation. Designed for highways, railways, and urban infrastructure projects, it helps mitigate traffic noise while generating clean, renewable energy.

As part of a comprehensive noise control system, it can be combined with Metal Louver Noise Barrier, Metal Perforated Noise Barrier, Acrylic Noise Barrier, and Fully Enclosed Noise Barrier to meet different project requirements. LUOFU also provides Highway Guardrail Systems and Traffic Safety and Road Management Products, supporting integrated solutions for noise control, road safety, and transportation infrastructure.

Material & Structural Behaviour

This dual-function system replaces traditional passive panels with TOPCon or Monocrystalline Silicon high-efficiency solar cells protected by double-tempered glass.

  • Power Generation & Efficiency: Delivers a power output of 180–400Wp per module with conversion efficiencies between 18.4% – 21.9%. The surface is treated with a self-cleaning photocatalytic coating to maintain efficiency with minimal maintenance.
  • Acoustic Excellence: Achieves a superior Noise Reduction Coefficient (NRC 0.75 – 0.95) by combining the glass surface with an integrated sound-absorbing core, effectively mitigating mid-to-high frequency traffic noise.
  • Structural Resilience: Engineered to withstand extreme wind loads (±4.0 ~ ±5.5 kPa). The dual-glass assembly is highly impact-resistant, passing TUV/CE certifications to ensure safety in high-density traffic areas.

Double-Sided Photovoltaic Noise Barrier

The Photovoltaic Noise Barrier combines road noise reduction with solar power generation, providing an efficient solution for green infrastructure and sustainable energy applications.

By utilizing existing roadside space, the system performs the noise reduction function of a conventional acoustic barrier while converting solar energy into electricity, maximizing the value of available infrastructure space.

Featuring a double-sided photovoltaic design, the PV modules are integrated into the noise barrier structure. The generated electricity can be supplied to the grid or used for applications such as road and infrastructure lighting, depending on project requirements.

This dual-function design combines noise control with clean energy generation, helping improve the overall environmental and economic value of transportation infrastructure.

Characteristics of Double‑Sided Photovoltaic Noise Barriers

– Saves valuable land resources and contributes to local energy‑saving and emission‑reduction goals.
– Double‑sided light‑harvesting design delivers up to 30% higher power output compared with single‑sided solar modules.
– Boosts power‑generation efficiency, mitigates light pollution and achieves effective resource conservation.
– Safe and reliable photovoltaic power generation without compromising the sound absorption and noise‑reduction performance of noise barriers.

Performance

Hybrid Absorption Technology

The system features an integrated Foam Aluminum acoustic core （20 – 30mm thickness) which provides broadband absorption. This allows the barrier to function as both a reflective insulation wall and an absorptive noise reducer.

Durability & Weather Resistance

Designed for a 25-year service life, synchronized with the lifespan of the PV modules. The back plates utilize zinc-aluminum-magnesium steel for superior corrosion resistance, passing the 1500h salt spray test. It operates reliably in extreme temperatures ranging from -30oC to +85oC

Safety & Fire Protection

The entire assembly is rated Class A (Non-combustible). The tempered glass ensures that even under impact, no sharp shards are produced, maintaining structural integrity and electrical safety.
