In the global wave of energy transition and sustainable development, solar lighting technology is gradually becoming the preferred solution for urban infrastructure upgrades due to its high efficiency and environmental friendliness. As a tropical island nation in the Indian Ocean, Mauritius has successfully implemented a road solar lighting project by leveraging its abundant solar resources and firm commitment to green development.

Background and Core Objectives

Mauritius is renowned for its picturesque island scenery and tropical marine climate, and it also boasts abundant solar energy resources. However, in certain road areas, traditional grid-powered lighting systems face numerous challenges: high installation costs, complex maintenance procedures, and unsustainable energy consumption.

To address these issues, a local government or relevant department in Mauritius launched a road lighting renovation plan with the following key objectives:

• Energy Sustainability: Fully leverage the region’s rich solar energy to reduce dependence on the traditional power grid.

• Energy Conservation and Emissions Reduction: Decrease energy consumption and carbon emissions to align with global climate initiatives.

• Road Safety: Provide stable, efficient lighting at night to protect pedestrians and vehicles.

• Convenience and Durability: Adopt systems that are easy to install and maintain, while withstanding the extreme tropical weather conditions, including heavy rains and hurricanes.

Based on these needs, Sresky’s BASALT series solar street lights were selected as the core solution for the project, with 120 units deployed to illuminate critical road sections.

Technical Solution: Innovative Design and Advantages of the BASALT Series Streetlights

Sresky’s BASALT series solar streetlights, equipped with advanced technologies and reliable performance, proved to be the ideal choice for the Mauritius road lighting initiative. The series offers brightness levels ranging from 4,000 to 12,000 lumens, flexibly adapting to various road lighting scenarios. Its core technological strengths include:

Integrated Design and Exceptional Weather Resistance

The BASALT series features an all-in-one aluminum frame with a robust structure and excellent fracture resistance, capable of withstanding extreme weather such as hurricanes. The lights are rated IP65 for dust and water resistance and IK08 for impact protection, ensuring stable operation even in Mauritius’ rainy, tropical climate.

High-Performance Energy Management

• POWER Lithium-Ion Batteries: Deliver reliable power to maintain uninterrupted nighttime lighting.

• TCS Battery Temperature Control Technology: Protects battery performance in both high and low temperatures, prolonging battery life—perfectly suited for the tropical climate.

• ALS2.4 Adaptive Lighting System: Intelligently adjusts brightness to optimize energy use, enabling more than five days of operation during extended cloudy or rainy periods.

High-Efficiency Lighting and Smart Control

• OSRAM 3030 LEDs: Provide luminous efficacy of up to 230 lm/W, a 4000K color temperature, and CRI >70, offering bright, comfortable illumination.

• Multiple Lighting Modes: Includes PIR sensor modes (M1, M2) and a constant-on mode (M3), supports button-switch control, and features a low-battery indicator for flexible use.

• Scientific Light Distribution: Employs Type 4S optics for wide-angle, high-penetration lighting, ensuring even road coverage with no dark spots.

In this project, 120 BASALT streetlights were flexibly configured based on road width and lighting requirements to optimize lighting coverage.

Project Implementation: Seamless Execution from Planning to Installation

Deployment Strategy

The project team planned 120 installation points to maximize road coverage. Based on BASALT series specifications, appropriate pole heights and models were selected. Panel orientation and tilt angles were optimized to ensure maximum exposure to sunlight.

Installation Process

The installation process followed a standardized and efficient approach:

• Foundation Construction: Holes were excavated according to base cage dimensions. C20 concrete was poured to ensure stability.

• Light Fixture Assembly: Brackets were attached to the light fixtures and then secured to the poles.

• Pole Installation: Manual or mechanical lifting was used to position and align poles with the foundations, followed by firm anchoring.

Logistics Support

All 120 BASALT streetlights and accessories were transported following Sresky’s packaging standards. Each light fixture was packed in an individual inner box, then placed in a color box. Brackets were packed eight per box to ensure safety and product integrity during transit.

Project Outcomes: Green Lighting Empowering Mauritius

Since implementation, the project has delivered remarkable results and long-term impacts:

1. Improved Road Safety

The 120 BASALT lights provide consistent, bright illumination for the road. Even in overcast or rainy weather, the ALS2.4 system guarantees sufficient brightness, reducing traffic accident risks and ensuring safe travel for both drivers and pedestrians.

2. Energy Independence and Cost Savings

By relying entirely on solar power, the project eliminates dependency on the electrical grid, cutting long-term operational costs and saving the local government substantial energy expenses.

3. Environmental Protection and Sustainable Development

This zero-emission lighting solution significantly reduces the region’s carbon footprint, aligning with Mauritius’ green development goals and serving as a replicable model for sustainable energy use.

4. Enhanced Urban Aesthetics

The modern, eco-friendly design of the solar streetlights enhances visual appeal and highlights Mauritius’ leadership in green infrastructure and innovation.

5. Low Maintenance and High Reliability

The BASALT series features a highly durable design, built-in alarm features, and a 3-year warranty. These factors contribute to reduced maintenance costs and ensure long-term operational stability.

Conclusion: A Future Benchmark for Sustainable Lighting

The successful execution of the Mauritius Road Solar Lighting Project demonstrates the superior performance, durability, and smart technology of the Sresky BASALT series. It delivers safe and efficient lighting to the local community and serves as a practical, scalable model for sustainable development—both in island nations like Mauritius and in other regions worldwide.
