Why does the Southeast Asian market prefer large-sized solar street lights?

The Southeast Asian market's preference for large-sized solar streetlights stems from a comprehensive fit with three key factors: regional environment, usage needs, and infrastructure characteristics. The specific reasons can be summarized in the following five points, concisely and directly relevant to the export scenario:

1. Climate Adaptability: Coping with Strong Winds and Rain + Maximizing Sunlight Utilization

Southeast Asia experiences frequent typhoons and torrential rains (such as Thailand, the Philippines, and Malaysia). Larger street lights have thicker poles and heavier bases, offering stronger resistance to wind loads (typically requiring ≥12 levels) and torrential rain erosion, resulting in a lower failure rate.Larger sizes allow for larger solar panels (e.g., 60W+), fully utilizing the abundant local sunshine (2000-3000 hours of sunshine per year), improving power generation efficiency, and meeting the demand for "long-lasting" operation.

2. Scenario Requirements: Covering Wide Roads + Remote Areas Without Power Grid Southeast Asia is experiencing rapid infrastructure development, with numerous wide roads, industrial parks, and rural main roads. Large-sized streetlights offer higher lighting power (30W-100W) and a wider illumination radius (15-30 meters), meeting the demand for "strong light and wide coverage." In rural and remote areas with insufficient power grid coverage, large-sized streetlights are typically equipped with larger capacity lithium batteries (e.g., 100Ah+), providing longer battery life (5-7 days of continuous operation in cloudy or rainy weather) and eliminating reliance on mains power.

3. Perception of Cost-Effectiveness:The Market Consensus of "Larger = Durable + Worry-Free"

Southeast Asian users (especially government projects and engineering procurement companies) generally believe that "larger size = more robust materials." Larger streetlights have more robust housings and battery compartments, resulting in a longer lifespan (typically claimed 5-8 years), meeting local demands for "long-term use and low maintenance" in infrastructure. While the initial purchase cost of large streetlights is slightly higher, the lack of electricity costs and low maintenance frequency lead to lower long-term overall costs, aligning with the Southeast Asian market's core demand for "high cost-effectiveness."

4. Policy and Standards Guidance: Specifications Required for Engineering Procurement

Many Southeast Asian countries (such as Indonesia and Vietnam) have specific requirements for the "power, illumination range, and wind resistance" of solar streetlights in their government infrastructure projects (roads, parks, community renovations). Larger streetlights are more likely to meet these bidding specifications. Import standards in some regions favor "high-power, large-size" products (e.g., requiring solar panel power ≥ 50W), making it easier for larger streetlights to pass compliance testing and reducing import risks.

5. Visual and Functional Extensions: Balancing Practicality and Scene Adaptability Large-size streetlights have taller poles (typically 6-8 meters), making them more visually striking in open roads and squares, and serving both "lighting + signage" functions. Some large-size streetlights can integrate additional functions such as monitoring, charging stations, and WiFi, meeting the extended needs of smart city and rural revitalization projects in Southeast Asia, and are more favored by buyers.
