Abstract:
In the West African nation of Ivory Coast, a community store successfully overcame the challenges of nighttime operations by deploying Sresky integrated solar streetlights, transforming into a beacon of safety and a social hub for the local community. This case study vividly illustrates the pivotal role that distributed solar lighting solutions play in enhancing small business service capabilities, stimulating the nighttime economy, and strengthening community safety. With all-weather reliability, intelligent energy management, and ease of deployment, Sresky streetlights offer an ideal model for commercial development in regions with inadequate power infrastructure.
1. Project Background and Needs Analysis
Project location: In front of a community store in Côte d’Ivoire.
This street-front store, located beside a community traffic light, serves as a key hub for local commercial activity. During the day, the area buzzes with people and vehicles—motorcycles, cars, and bicycles—demonstrating its vibrancy as a community service point.
However, when night falls, several critical challenges arise:
-
Limited operating hours: In areas with an unstable power supply, nighttime business becomes nearly impossible. As a result, the store is unable to provide residents with essentials such as food, daily necessities, and phone recharge cards after dark, severely limiting both service capacity and revenue.
-
Safety hazards: Without reliable external lighting, the store’s entrance area becomes completely dark. This discourages nighttime customers and creates opportunities for crimes such as theft or robbery, threatening the safety of the shop owner, customers, and assets.
-
Disruption of community vitality: The store’s frontage is a natural gathering spot. Inadequate lighting causes residents to retreat indoors after sunset, and motorcycle drivers avoid waiting for passengers there, leading to a near standstill of community activity and economic exchange.
To overcome these issues, the store owner urgently needed an independent, stable, off-grid, and adequately bright lighting solution to extend operational hours and create a safe, inviting environment.
2. Technical Solution Design: The Perfect Match with Sresky Solar Streetlights
To address these needs with precision, the project adopted Sresky integrated solar streetlights. This solution incorporates several industry-leading technologies, offering a comprehensive and efficient approach.
-
Absolute reliability – Ensuring uninterrupted operation:
-
ALS2.4 Core Technology (Adaptive Lighting System): This is the backbone of reliable lighting during prolonged adverse weather—such as the rainy season in Ivory Coast. The system intelligently manages battery output, ensuring continuous illumination for up to 10 consecutive rainy days, guaranteeing stable business operations.
-
TCS Intelligent Temperature Control System: Designed for Côte d’Ivoire’s hot climate, the TCS protects the battery and ensures efficient operation within a temperature range of −20°C to +60°C, while also extending the battery’s service life.
-
-
Intelligent operation – Demand-based lighting and energy efficiency:
-
PIR smart sensing: Equipped with a 120° wide-angle infrared sensor and an 8-meter detection range, the lights automatically dim during periods of low traffic. When motion is detected—whether from pedestrians or vehicles—the lights instantly return to 100% brightness. This suits the store’s intermittent customer flow and optimizes energy use.
-
Flexible lighting modes: Pre-set smart lighting options (e.g., M2: 5 hours at 100% brightness + 5 hours at 25% with PIR sensor + 70% until dawn) allow the store owner to choose the most suitable mode based on business hours and foot traffic, ensuring a balance between lighting performance and power consumption.
-
-
Exceptional performance – Bright, durable lighting:
-
High luminous efficacy: Using OSRAM LED chips with luminous efficacy up to 230 lm/W, the system produces strong illumination with lower energy consumption. The installed lights provide clear, even coverage across the storefront.
-
Durable design: Constructed with aluminum alloy and PC materials, the light body offers IP65/IK08 protection, delivering excellent resistance to water, dust, and impact—perfect for demanding outdoor conditions.

3. Project Implementation and Deployment
The installation process of the Sresky integrated solar streetlights showcases their simplicity and efficiency:
-
Easy installation: No need to excavate roads, lay cables, or connect to the grid. Installation involves creating a cement base, attaching the bracket and lamp to the pole, and erecting the entire structure. This process is quick and minimizes disruption to the store’s operations.
-
Low maintenance: Modular design allows components to be replaced directly on the pole if needed. This greatly reduces long-term ownership costs—especially important in areas lacking access to professional maintenance personnel.
Once installed, as shown in the accompanying images, a single streetlight completely transforms the store’s nighttime appearance—turning it from a typical roadside shop into a visible, safe, and inviting nighttime landmark.
4. Risks and Mitigation Strategies
-
Identified risks:
-
Extreme weather: Extended periods of heavy rain or sandstorms beyond the system’s design thresholds could hinder charging efficiency.
-
Vandalism or theft: As outdoor assets, solar lights are vulnerable to damage or theft.
-
-
Mitigation strategies:
-
Technical safeguards: Sresky’s ALS technology mitigates weather-related performance issues. Combined with high-efficiency solar panels and robust battery systems, this ensures operational resilience.
-
Community co-management & robust design: The IK08-rated build provides strong physical durability. More importantly, when the community and store benefit from the lighting, they naturally become its protectors. This sense of ownership becomes the best form of security.
-
Conclusion
The Sresky solar streetlight project in Ivory Coast is a classic example of a successful pilot initiative with wide-reaching implications. By addressing the needs of a small commercial storefront, it unlocked the greater goals of activating the local nighttime economy, enhancing public safety, and improving community life. This case convincingly demonstrates that high-quality, intelligent solar lighting is not just about illumination—it is essential infrastructure that drives economic development, community engagement, and sustainable progress across the developing world.
