Wide-Spacing Roadway Retrofit: ST2-60 Solar Street Light Deployment

Project Overview

This case study highlights a successful municipal infrastructure upgrade on a busy suburban connector road. The primary objective was to implement a highly cost-effective and sustainable lighting network while matching the existing infrastructure footprint without extra civil works.

Project Challenges & Requirements

The local municipality required a robust solar roadway lighting solution capable of maintaining a wide 30-meter pole spacing. This strict constraint was critical to leverage existing pole locations and completely eliminate disruptive civil works, cable trenching, and grid connection gridlocks along the established suburban connector road.

Technical Solution: RoadSmart ST2-60 Integrated Solar Light

To deliver optimal road-class illumination across extended spans without compromising safety, RoadSmart deployed the ST2-60 integrated solar street light series, featuring high-efficiency components engineered for autonomy and uniformity:

• Luminous Flux: 10,000 lm (High-brightness LEDs)
• Solar Panel: 80W / 18V Monocrystalline (Fast charging even on cloudy days)
• Battery Capacity: 384Wh Grade-A LiFePO4 (Supports 3-5 rainy days autonomy)
• Installation Height: 7 m
• Design Pole Spacing: 30 m (Optimized light distribution)

Proven Verification & Achievements

By utilizing specialized bat-wing professional optics, the ST2-60 delivered excellent road-class uniformity, completely eliminating dangerous dark zones between the extended 30m intervals. The project successfully achieved a 25% reduction in overall fixture count compared to standard alternatives, drastically lowering upfront capital expenditure. By avoiding traditional grid trenching, the system eliminated municipal installation delays, while 100% solar energy ensures near-zero ongoing operating costs.
