Brazzaville, Congo - Town branch road lighting: ST2-80 deployment
Project at a Glance
At a glance
Project Challenge
Weak Power Infrastructure
Limited grid coverage in some districts of Brazzaville meant traditional street lights relied on unstable municipal power, leading to frequent blackouts and safety hazards at night.
Tropical Climate Stress
High temperature and humidity accelerated component aging, while prolonged rainy seasons drastically reduced solar charging efficiency, threatening night-time lighting continuity.
Complex Commercial District Lighting Needs
Balanced high-brightness requirements for main roads and low-glare needs for sidewalks was critical, while avoiding light pollution affecting nearby residents.
Limited Local Maintenance Capacity
A lack of professional lighting maintenance teams made traditional street light inspection and repair costly and unsustainable for long-term operation.

Lessons Learned & Best Practices
Environment-First Design
For tropical high-temperature and high-rainfall regions, prioritize all-in-one solar products with high temperature resistance and IP66 protection, while optimizing battery capacity and charging efficiency.
Scenario-Based Layout
Commercial districts require balanced brightness and glare control; precise spacing and pole height ensure both safety and comfort.
Smart Energy Savings
Light + motion sensing dimming is a key advantage for African projects, meeting lighting needs while maximizing rainy-season battery life.
Lightweight O&M
All-in-one products + remote monitoring perfectly address limited local maintenance capacity, cutting long-term upkeep costs.

FAQs
Can the ST2-80 solar street light operate reliably in Congo-Brazzaville’s tropical rainy season?
Yes. The ST2-80 is equipped with a high-efficiency MPPT charge controller and large-capacity lithium battery, which boosts charging efficiency by over 20% even in overcast conditions. It has been field-tested to maintain 100% full-night lighting for 7 consecutive rainy days, fully meeting the needs of Brazzaville’s long rainy season.
How does the ST2-80 perform in high-temperature environments?
The ST2-80 features a wide operating temperature range of -20°C to 60°C and uses heat-resistant electronic components and optimized heat dissipation design. It can operate stably in Congo-Brazzaville’s high-temperature (up to 35°C+) environment, with no performance degradation or accelerated aging issues.
Is professional installation required for the ST2-80? Can local teams handle it?
No professional installation is needed. The all-in-one design eliminates complex wiring and trenching; a single pole can be installed by 2 local workers in just 1 hour. We also provide on-site technical training and detailed installation manuals to ensure local teams can complete the work independently.
What is the maintenance cost compared to traditional grid-powered street lights?
The ST2-80 has no electricity bills and requires minimal maintenance. With smart remote monitoring and fault alerts, the annual maintenance cost is reduced by over 80% compared to traditional grid lights. The battery and LED module have a lifespan of 5–10 years, further lowering long-term replacement costs.
Can the ST2-80 be customized for different road widths or lighting needs?
Yes. We offer ODM customization for LED power, battery capacity, solar panel size, and control modes. For example, we can adjust the pole height and spacing for narrow residential streets or higher-power configurations for busy main roads, ensuring the solution perfectly matches your project’s specific requirements.
