Main Road Solar Street Light Project: NH100 35m Pole Distance Deployment
Engineering Case Study & Infrastructure Optimization
Project Background
Regional arterials and major roadways often face severe safety hazards due to inadequate night-time illumination. In this infrastructure upgrade project, the municipality required a reliable, energy-efficient, and sustainable highway lighting solution. Because the project spanned a remote regional arterial, extending the traditional electric grid would involve high-cost trenching, cable laying, and lengthy administrative approvals, making an off-grid smart solar street light project the ideal choice.
The Challenges
The primary challenge of this main road illumination project was balancing cost efficiency with strict highway lighting safety standards. The engineering firm specified an extended pole spacing of 35 meters with a 6-meter installation height to minimize the total infrastructure budget. Standard solar lights often leave dangerous "dark zones" between poles at this distance. The solution demanded specialized optics to achieve uniform lux distribution across the primary roadway without increasing the LED power consumption.
Technical Solution & Engineering Specifications
Roadsmart deployed the NH100 integrated solar street light, a high-efficiency 20W solar lighting system engineered precisely for regional arterials. Based on professional DIALux lighting simulations, the NH100 was configured with premium components to ensure 100% reliable off-grid operation even during consecutive rainy days.
| Application Field | Primary Roadway / Regional Arterial |
| Light Source Power | High-efficacy 20W LED Engine (120 lm/W) |
| Installation Setup | 6m Height | 35m Pole-to-Pole Spacing |
| Core Components | Monocrystalline Silicon Panel & Bat-wing Lens |
Key Achievements & ROI Benefits
The NH100 deployment delivered outstanding economic and technical performance, proving the feasibility of low-power, wide-spacing solar lighting:
- Excellent Lighting Uniformity: The advanced bat-wing optics effectively stretched the light pattern, eliminating dark spots and ensuring uniform coverage across the entire main road.
- 30% Reduction in Infrastructure Budget: By successfully achieving a 35m pole distance (compared to the standard 25m spacing), the project required fewer poles and fixtures, drastically cutting initial procurement and installation costs.
- Zero Electricity Bills & Low Maintenance: The 100% off-grid system requires no trenching or external electricity. Equipped with intelligent power management, the fixtures ensure continuous autonomous operation with virtually zero maintenance demand, maximizing long-term ROI for the client.
