Reliable Residential Solar Street Lighting in Vietnam – Powered by Queneng
In August 2024, Queneng Lighting completed a strategic solar lighting deployment for a large-scale residential housing development in northern Vietnam. Designed to operate efficiently even in high-humidity and rainy conditions, this project aimed to improve outdoor visibility, reduce electrical costs, and contribute to Vietnam’s push toward clean energy adoption.
The project demonstrated Queneng’s ability to deliver customized, weather-adaptive solar lighting systems suited for tropical residential applications — ensuring both safety and sustainability for communities.
🏗️ Project Background:
Vietnam’s rapid urbanization has increased the demand for modern infrastructure in residential districts, including dependable and sustainable lighting solutions. This particular development, covering 18 hectares and housing over 600 families, faced:
-
Inadequate legacy lighting (dim, costly, and grid-reliant)
-
Frequent power cuts during the rainy season (June–October)
-
High maintenance costs and unreliable energy availability
-
Government encouragement of green energy usage through building codes
The real estate developer needed a cost-effective, off-grid lighting solution that could function through variable weather, especially long rainy spells — and do so with minimal upkeep.
💡 Queneng’s Customized Lighting Solution
After evaluating site conditions — including monsoon rainfall, narrow residential lanes, and limited maintenance workforce — Queneng delivered 280 units of a specially designed QN-SSL-60W Tropical-Climate Series:
| Component | Specification |
|---|---|
| Solar Panel | 18V / 120W high-efficiency monocrystalline (anti-fog coating) |
| Battery | 12.8V / 60Ah LiFePO₄, deep cycle with smart BMS |
| LED Light | 60W, 160lm/W efficiency (approx. 9,600 lumens) |
| Control System | Automatic dusk-to-dawn + motion sensor override |
| Material | IP66-rated die-cast aluminum, with corrosion-resistant coating |
| Mounting Pole | 6-meter hot-dip galvanized pole (powder-coated in black matte) |
| Rainy Day Backup | ≥4 consecutive days without direct sunlight |
| Lighting Modes | Full brightness at peak hours, dimming at late night, sensor-based triggering in lanes |
To preserve aesthetics and avoid light pollution, units were installed along internal paths, playgrounds, parking areas, and security gates with carefully planned intervals.
