Solar Street Light project in Vietnam

Project Name: Infrastructure Lighting for New Urban Areas in Vietnam
Location: An Emerging Urban Development Area in Vietnam
Product: Sresky SSL-310 Solar Integrated Street Light
Quantity: 48

Project Overview

With Vietnam’s rapid economic growth and large-scale urbanization, the demand for modern, efficient, and sustainable urban infrastructure is increasing. This project focuses on a newly developed urban area in Vietnam, aiming to build a modern, eco-friendly community. To meet the basic street lighting needs of this new area and align with global trends toward green energy and sustainability, the project adopted Sresky’s SSL-310A solar-integrated street lights. With a proven track record of winning over 3,500+ bids globally, Sresky is a highly trusted brand with reliable products, significantly reducing the investment risk associated with infrastructure projects.

The project area is remote and still under development, facing the following challenges:

• Unstable or unavailable power supply, with an urgent need for off-grid lighting solutions

• Large temperature fluctuations and high humidity requiring lighting equipment to be highly adaptable

• Limited resources for future maintenance; therefore, products must be low-maintenance and highly reliable

• Increasing focus on sustainability, requiring lighting systems to minimize their carbon footprint

To address these needs, the project team chose to deploy Sresky’s flagship product — SSL-310A high-performance integrated solar street lights. A total of 48 units were installed along the main roads, creating an independent, efficient, and environmentally friendly lighting system.

Sresky SSL-310A Core Technical Advantages

High Luminous Efficacy and Brightness

The SSL-310A delivers up to 10,000 lumens using 160 OSRAM 3030 LED chips, achieving a luminous efficacy of 230 lm/W. This ensures powerful, uniform illumination across the open roads of the new urban district.

Advanced Solar System and Long Battery Life

• Equipped with 75W high-efficiency monocrystalline silicon solar panels, with a solar charging efficiency exceeding 21%, ensuring rapid energy collection in Vietnam’s sunny climate (average charging time ~7.7 hours).

• Features a 14.8V, 692.64WH Li-FePO₄ lithium battery, supporting 1,500+ cycles, ensuring long-lasting power.

• Integrated ALS 2.4 (Adaptive Lighting System) and BMS (Battery Management System) technologies allow lighting for over 10 days in cloudy/rainy conditions. BMS also increases charging efficiency by over 30%, maintaining lighting continuity.

Intelligent Control and Multiple Lighting Modes

• Equipped with a push-button switch (1.5s to power on/off, 6s to reset)

• Offers three lighting modes (M1, M2, M3) for flexible energy-saving settings

• Includes power and mode indicators for easy management and maintenance

High Protection and Durability

• Constructed with aluminum and PC materials for a robust build

• Rated IP65/IK08 for dust, water, and impact resistance

• Bracket features double anti-rust protection for extended lifespan

• TCS (Temperature Control System) ensures safe operation across a wide temperature range (charging: 045°C, discharging: -2060°C), with protection up to 65°C

Simplified Installation and Maintenance

• Recommended mounting height: 10m, spacing: 32m for wide-area coverage

• Modular, integrated design enables fast installation and easy maintenance — all components can be replaced directly on the pole, reducing downtime and labor costs

• Local technicians can be easily trained, fostering local employment and creating a sustainable maintenance ecosystem

• Backed by a 3-year manufacturer’s warranty
