Siemens Solar Traffic App 1: Solar-Powered Traffic Lights for Remote Roads
Siemens Solar introduces its Traffic Application 1, a pioneering solar-powered solution designed to energize traffic lights in remote and off-grid locations, ensuring safe and reliable traffic management where traditional power sources are unavailable. Utilizing our advanced photovoltaic (PV) modules such as the SR50 and SP36, this initiative provides a sustainable, fuel-free power source for traffic light systems critical to road safety in isolated areas. This article expands on the original Traffic App 1 page from our website, offering an in-depth guide to the technology, system design, installation process, benefits, and real-world applications, showcasing Siemens Solar’s expertise in enhancing traffic infrastructure with renewable energy.
The Need for Solar-Powered Traffic Lights
Traffic lights are essential for managing road safety, yet in remote regions, grid power is often absent, forcing reliance on diesel generators costing $500-$1,000 per kW annually and emitting 2-4 tons of CO2 per kW, according to industry estimates. Siemens Solar’s Traffic App 1 addresses this challenge with SR50 modules, delivering consistent power to traffic lights without the logistical burden of fuel delivery. With over 1 million off-grid infrastructure points globally by 2023, as noted by a1solar.co.uk, this solution enhances safety and sustainability.
Why Solar-Powered Traffic Lights?
- Reliability: Ensures continuous traffic light operation.
- Cost Savings: Saves $300-$600 yearly per kW versus diesel.
- Sustainability: Reduces emissions by 1-2 tons per kW annually.
- Remote Deployment: Powers lights beyond grid access.
Technology Overview
The system integrates SR50 (50W) or SP36 (36W) modules, PWM charge controllers, inverters, and battery storage, optimized for traffic light power demands.
System Components
| Component | Feature | Benefit |
|---|---|---|
| SR50/SP36 Modules | 14-15% efficiency | Reliable power output |
| Charge Controller | 10-20A PWM | Protects battery health |
| Battery Storage | 5-10 kWh | Ensures 24/7 light operation |
A 1 kW SR50 array generates 1,400-1,600 kWh annually, powering a traffic light system with a 5 kWh battery for round-the-clock functionality.
Installation Process
- Site Assessment: Evaluates sunlight and traffic light power needs.
- Design: Customizes array and battery placement.
- Setup: Installs in 1-2 days with sturdy mounts.
Case Studies
