🧠What Are Solar Roads?

Solar roads are road surfaces embedded with photovoltaic (PV) panels that generate electricity while supporting traffic.

Key Features:

• Solar cells beneath durable transparent surfaces
• Embedded LEDs for dynamic markings
• Heating systems to prevent snow and ice

These roads convert sunlight into electricity, enabling:

• Smart lighting
• Traffic management systems
• Potential EV charging infrastructure

👉 Essentially, they transform roads into energy-producing smart infrastructure.

⚙️ How Solar Roads Work

1. Sunlight passes through a transparent surface layer
2. PV cells convert light into electricity
3. Energy is stored or sent to the grid
4. Sensors and LEDs enable smart road functionality

Advanced panels also include:

• Microprocessors for real-time monitoring
• Heating elements for safety
• Modular designs for easier maintenance
