1. Project Background and Needs Analysis
1.1 Project Overview
Project Location: A major urban area in Nigeria, covering commercial streets, residential neighborhoods, parking lots, tree-lined avenues, under-bridge zones, and other functional urban areas.
Project Background:
With the acceleration of Nigeria’s urbanization, this region faces severe challenges including an unstable power supply and insufficient nighttime lighting. Frequent grid outages hinder nighttime activities, jeopardize public safety, and constrain economic development. This project aims to deploy an independent, energy-efficient solar lighting system to enhance the city’s image, improve residents’ quality of life, and boost the nighttime economy.
Core Challenge:
How to deliver a differentiated, full-coverage lighting solution across a city with diverse urban scenarios—ensuring high-brightness in commercial zones, comfort in residential areas, security in public spaces, and illumination of previously neglected blind spots.
1.2 Precision Lighting Requirements in Diverse Scenarios
Commercial and Transportation Hubs
-
Scene Characteristics: Busy roads, heavy vehicle and pedestrian traffic, and a dynamic nighttime economy.
-
Lighting Requirements: High-brightness, high-reliability lighting to support safe transit, commercial activity, and a vibrant urban environment.
Public and Open Spaces
-
Scene Characteristics: Parking areas, walking paths, and other zones with lower foot traffic that can pose safety risks at night.
-
Lighting Requirements: Adequate illumination to ensure safety while incorporating smart energy-saving functions to reduce unnecessary power use.
Residential Areas
-
Scene Characteristics: Quiet community streets where residents prioritize safety and visual comfort.
-
Lighting Requirements: Gentle, glare-free lighting that ensures nighttime safety without disturbing sleep or residential tranquility.
Special Infrastructure Zones
-
Scene Characteristics: Structured but often-overlooked areas like underpasses and bridges that can become urban “blind spots.”
-
Lighting Requirements: Eliminate dark areas to ensure functional visibility and public safety.
2. Technical Solution Design

-
In residential or secondary streets, 6,000 LM and 4,000 LM models offer balanced brightness for comfort and functionality.
-
Core Technology 1: ALS2.4™ Patented Technology – 24/7 Reliability
-
Feature: Intelligent energy management system enables normal operation even after 5 consecutive days of rain.
-
Relevance: During Nigeria’s extended rainy season, ALS2.4 ensures consistent lighting regardless of weather or grid disruptions—crucial for public safety and urban resilience.
Core Technology 2: TCS™ Smart Temperature Control – Built for Heat
-
Feature: Regulates internal battery temperature for stable operation between -10°C and 60°C.
-
Relevance: Nigeria’s hot climate can shorten battery lifespan. TCS extends battery life, ensuring the Basalt lights perform reliably in tropical environments.
Core Technology 3: PIR Smart Sensing – Maximized Energy Efficiency
-
Feature: Motion-sensing system dims lights to 30% when inactive and boosts to 100% when motion is detected (120° range, 8-meter radius).
-
Relevance: In low-traffic areas like pathways, parking lots, and residential zones, this system reduces energy usage without compromising safety.
Core Technology 4: FAS™ Fault Self-Diagnosis – Simplified Operations & Maintenance
-
Feature: Automatically detects faults and issues system alerts, eliminating manual troubleshooting.
-
Relevance: With thousands of lights citywide, FAS reduces maintenance workload and cost, empowering municipal teams to quickly respond and resolve issues.
Durable Construction and Professional Optical Design
-
Structure: Integrated aluminum frame with IP65 waterproof and IK08 impact resistance ratings; hurricane and fracture-resistant design.
-
Optical Performance: Type 4S light distribution ensures wide, even coverage and deep road penetration for uniform illumination.
3. Project Implementation and Deployment
Strategic Deployment: Lighting Every Corner of the City
Before installation, the project team conducted a detailed urban lighting survey to assess the unique functional needs of each zone. A scientifically designed deployment plan was created, ensuring the appropriate Basalt model was installed in each district—northeast, southeast, northwest, and southwest.
The installation process followed strict protocols, including foundation pouring, pole anchoring, and electrical commissioning. These procedures ensured quality, minimized disruption, and maintained urban traffic and pedestrian flow.
4. Project Outcomes and Impact
4.1 Significant Social Value
-
Improved Public Safety: Continuous, bright lighting significantly reduced nighttime crime—especially in commercial and residential areas—enhancing the sense of security. Women, children, and other vulnerable groups now feel safer traveling at night.
-
Elevated Quality of Life: Residents can now safely use parks, streets, and public amenities after dark, improving quality of life and neighborhood interaction.
4.2 Substantial Economic and Environmental Value
-
Zero Electricity Bill: Powered entirely by solar energy, the lighting system incurs no electricity cost—saving municipal resources and promoting fiscal sustainability.
-
Reduced Maintenance Costs: With long-life components, a 3-year warranty, and the FAS system, the Basalt series significantly lowers the cost and complexity of maintenance operations.
-
Green Urban Benchmark: This project sets a precedent for clean energy adoption in Nigerian cities, providing a replicable model for sustainable urban lighting.
Conclusion
The Nigeria Urban Road Solar Lighting Project has successfully implemented a smart, sustainable, and citywide lighting solution using Sresky Basalt solar street lights. The project addressed key challenges such as unreliable grid power and inadequate nighttime illumination—while enhancing public safety, activating the nighttime economy, and improving urban livability.
