Thailand Solar Street Light Project – SRESKY Atlas Series for Farm Lighting

In the global process of agricultural modernization, solar lighting technology is emerging as a key driver of sustainable development. As a leading brand in the solar streetlight sector, SRESKY has delivered an efficient and reliable lighting solution for a large farm in Thailand through its Atlas series of integrated solar streetlights. This project not only addresses power shortages in remote areas but also ensures uninterrupted lighting throughout the year, even in a tropical climate with frequent rainy seasons.

I. Project Background and Needs Analysis

1.1 Project Background

Thailand, a major agricultural powerhouse in Southeast Asia, is renowned for its exports of rice, rubber, and fruits, with agricultural output contributing nearly 10% of its GDP. However, as climate change and urbanization accelerate, many farms face pressure to transition to renewable energy sources.

This project is located on a large integrated farm spanning hundreds of hectares in central Thailand. The farm combines rice cultivation, livestock farming, and fruit production, generating annual revenues in the millions of dollars. As operations expand, demand for nighttime lighting has increased significantly:

  • Internal roads require safe passage.

  • Livestock areas need protection against wildlife intrusion.

  • Living areas demand comfortable and reliable lighting.

The challenge lies in the farm’s remote rural location, where national grid coverage is below 30%. Traditional electricity supply is unstable and costly—laying power lines would require hundreds of thousands of dollars. The farm owner also aims to enhance brand image and attract international partners with a zero-carbon lighting system. The introduction of the SRESKY Atlas series solar streetlights became a strategic solution, proven in over 3,500 global tender projects.

1.2 Core Needs and Challenge Analysis

Based on on-site research and farm operation data, four core needs and challenges were identified, common to tropical agricultural environments:

  1. All-weather stable lighting: The rainy season (May–October) brings continuous rain for weeks, reducing solar charging efficiency. The farm requires lighting that operates normally even during more than 10 consecutive rainy days. Traditional solar lights often fail under these conditions.

  2. Environmental adaptability and durability: High temperatures and humidity cause corrosion and thermal degradation. The system must meet IP65 waterproof and dustproof standards and IK08 impact resistance ratings. Materials must be heat-resistant to ensure stable operation from -20°C to +60°C.

  3. Intelligence and energy efficiency: Traffic flow is uneven. Main roads require constant lighting, while remote paths benefit from on-demand lighting. Smart sensing reduces power consumption by over 70%, extends battery life (>1,500 cycles), and minimizes light pollution.

  4. Economy and maintenance: Zero electricity cost, easy installation, and low maintenance are essential. Components should be replaceable on light poles without high-altitude work. The system must be reliable to reduce maintenance frequency in remote locations.

These needs reflect global agricultural lighting challenges—balancing cost, performance, and sustainability. The SRESKY Atlas series aligns perfectly with these requirements through innovative technology.

II. Technical Solution Design

To address these challenges, the project team evaluated multiple options and ultimately selected the SRESKY Atlas series integrated solar streetlights. The series offers brightness levels from 2,000 LM to 10,000 LM, suitable for heights of 3–10 meters with spacing of 15–32 meters, adapting to diverse farm scenarios. Its design philosophy—“smart + durable”—integrates patented technologies to ensure superior performance in Thailand’s tropical climate.

2.1 Core Technical Advantages

  • ALS 2.2 Intelligent Power Regulation (Adaptive Lighting System): Maintains lighting even during long rainy seasons by adjusting power output based on weather forecasts and battery conditions. Ensures 100% year-round lighting.

  • TCS Smart Temperature Control (Temperature Control System): Provides real-time thermal management to prevent battery capacity loss from overheating.

  • PIR Human Infrared Sensing: Wide-angle (120°) detection up to 8 meters. Offers three modes:

    • M1: 30% brightness, 100% with presence

    • M2: 100% for 5 hours, then 25% + PIR, then 70% until dawn

    • M3: 70% constant brightness

  • BMS Battery Management System: Improves charging efficiency by 30%.

2.2 Top-tier Hardware Configuration

  • High-efficiency photovoltaic conversion: Monocrystalline panels paired with OSRAM LEDs provide Type 2 light distribution, 20% higher charging efficiency than polycrystalline panels.

  • Durable structure: Aluminum alloy + PC material, IP65/IK08 rating, dual anti-rust treatment, batteries fully charge in 6.7–10 hours. LED indicators simplify monitoring.

These configurations enable the Atlas series to excel in global tenders for agriculture and rural infrastructure.

III. Project Implementation and Deployment

3.1 Precise Planning and Deployment

The project installed 150+ streetlights across the farm, all within budget. Deployment details:

  • Main roads and entrances: SSL-38 and SSL-310 models, 8–10 m height, 28–32 m spacing.

  • Secondary roads and livestock areas: SSL-34 and SSL-36 models, 4–6 m height, 15–22 m spacing. PIR mode enabled.

  • Pathways and work areas: SSL-32A models, 3 m height, 15 m spacing.

This ensured 100% coverage with total brightness over 500,000 LM.

3.2 Efficient Installation Process

The Atlas series uses an integrated design for quick setup:

  1. Dig hole and pour concrete foundation.

  2. Attach bracket to luminaire.

  3. Mount luminaire to pole.

  4. Raise and secure the pole.

No wiring required; each light installs in under 30 minutes, cutting construction time by 50%. Farm workers can manage the system after basic training.

IV. Project Outcomes and Impact

4.1 Technical and Economic Value

  • 100% energy self-sufficiency: Off-grid, saving >$100,000 annually in electricity.

  • Reliable 24/7 operation: Normal lighting even after 10 consecutive rainy days.

  • Low maintenance: Modular, on-pole component replacement; lifespan >10 years.

4.2 Social Value and Sustainability

  • Enhanced safety: Reduced theft by 30%, fewer road accidents, safer night patrols.

  • Better work and living environment: Improved lighting increases employee satisfaction and attracts workers.

  • Green agriculture benchmark: Annual CO₂ emissions cut by 5+ tons, showcasing sustainable agriculture.

Conclusion

The solar lighting project at the Thai farm, powered by the SRESKY Atlas series streetlights, transforms climate challenges into opportunities. It highlights how modern solar technology can support agricultural development while promoting sustainability.
