Amidst the global wave of sustainable development, solar lighting technology is increasingly becoming the preferred solution for upgrading urban infrastructure. This article examines the implementation of SRESKY’s BASALT solar street lights in the public lighting system of a newly constructed large-scale commercial complex parking lot in Thailand. As a leading manufacturer specializing in solar lighting solutions, SRESKY demonstrates through this project the exceptional adaptability and economic value of its products in tropical climates. This case not only highlights the role of technological innovation in addressing energy costs, climate challenges, and safety requirements but also provides replicable reference experience for clients such as commercial real estate developers, property management companies, and municipal engineering contractors.
1. Project Background and Needs Analysis
As Southeast Asia’s economic hub, Thailand experiences rapid commercial real estate development. This project is located at a newly constructed large-scale commercial complex in suburban Bangkok, Thailand, with a total floor area exceeding 100,000 square meters. Its expansive open-air parking lot accommodates over 2,000 vehicles. As the “gateway” to the commercial complex, the parking lot experiences extremely high nighttime usage, particularly during holidays and evening shopping peaks.
However, when planning the lighting system, the owner faced multiple complex challenges that directly impacted the project’s overall operational efficiency and sustainability.
Energy Costs and Grid Dependency: Thailand’s commercial electricity rates have risen steadily in recent years. According to the Ministry of Energy, the average rate exceeded 4 baht per kWh in 2023. For a large-scale parking facility, providing full-night illumination translates to millions of baht in annual electricity expenses. Additionally, grid stability remains inconsistent in some regions, where voltage fluctuations and occasional outages could disrupt lighting operations and impact commercial activities.
Climate Adaptation Demands: Thailand’s tropical monsoon climate features an average annual temperature of 28°C (82°F), with frequent rainfall during the rainy season (May to October). This high-temperature, high-humidity environment challenges the durability of lighting equipment. Traditional lithium batteries are prone to performance degradation and safety hazards in such climates, while inadequate waterproofing can cause short circuits. Property owners require lighting systems that maintain stable operation under extreme weather conditions to avoid additional maintenance costs.
Safety and Security Requirements: Inadequate nighttime parking lot illumination contributes to traffic accidents and security incidents. According to Thailand’s Ministry of Transport, over 30% of parking lot accidents occur at night. The owner requires a high-brightness, blind-spot-free lighting solution to enhance visibility, deter potential crimes, and safeguard customer safety and property. The system must also support smart sensing capabilities to conserve energy during low-traffic periods.
Ease of Installation and Cost Control: Traditional wired lighting systems require extensive trenching and cabling, resulting in long construction cycles, high costs, and disruptions to parking lot schedules. Property owners favor wireless designs with modular installation for rapid deployment and optimized initial investment.
Considering these requirements, the owner evaluated multiple suppliers through a tender process and ultimately selected SRESKY’s BASALT series. This series perfectly matches the application scenario of Thai commercial parking lots with its integrated design and high adaptability.
2. Technical Solution Design
During the technical design phase, the SRESKY team collaborated closely with the owner to conduct site surveys and align requirements. After multiple rounds of evaluation, the BASALT series emerged as the preferred choice. This integrated solar streetlight combines advanced photovoltaic conversion, intelligent control, and weather-resistant technology, specifically engineered for large outdoor spaces. Below is an analysis of its key parameters and advantages.
Core Product Overview:
SRESKY BASALT is a high-power solar streetlight suitable for commercial parking lots, industrial parks, and municipal roads. Featuring an integrated aluminum frame and OSRAM LED chips, it delivers efficient, reliable lighting solutions. Official specifications indicate a luminous flux of up to 12,000 LM, a color temperature of 4000K, and a color rendering index (Ra) >70, ensuring natural light effects and comfortable visual experiences.
Key Technical Parameters and Advantages:
-
Ultra-High Brightness and Wide Coverage: BASALT achieves a luminous efficacy of 230 lm/W, significantly exceeding industry averages. Equipped with a professional Type 4S optical design (symmetrical wide-beam illumination), it delivers uniform, glare-free coverage. At the recommended installation height of 12 meters, luminaire spacing can reach 54 meters. This reduces the total number of poles required (e.g., only ~50 luminaires for a 2,000-space lot), cutting investment costs by 20%-30%. This design ensures smooth nighttime vehicle access and eliminates lighting blind spots.
-
Exceptional Climate Tolerance (TCS Technology): Thailand’s high temperatures can damage batteries. BASALT incorporates a patented Thermal Control System (TCS), enabling discharge from -20°C to +60°C and charging from 0°C to 45°C. Intelligent temperature regulation extends battery cycle life to over 1.5 times that of conventional lithium batteries. Field data shows that at 50°C, TCS battery capacity degradation is only 50% of non-TCS batteries.
-
Long-Lasting Performance During Rainy Days (ALS Technology): The patented Adaptive Lighting System (ALS 2.2) automatically adjusts power based on solar input, optimizing brightness during cloudy or rainy days to ensure over 10 days of continuous illumination. Compared to traditional solar lights, ALS boosts energy efficiency by 30%, eliminating the risk of blackout during the rainy season.
-
Robust and Reliable Structural Design: The luminaire features an integrated aluminum alloy housing with strong hurricane resistance. IP65 waterproof rating and IK08 impact resistance ensure stable operation in high-humidity and dusty environments. Weighing approximately 14.3 kg, it facilitates easy transportation and installation.
-
Intelligent Energy Management: A built-in PIR infrared sensor (120° detection angle, max 8m range) supports multiple modes, such as M2 mode (100% brightness for the first 5 hours, then 25% base + PIR-triggered 70%). This “on-demand lighting” saves over 50% energy during low-traffic late-night periods.
These specifications are based on official SRESKY data, ensuring scientific rigor and solution reliability. Compared to competing products, BASALT excels in tropical adaptability and intelligent control.
3. Project Outcomes and Impact
Upon implementation, the project immediately delivered multidimensional value exceeding the owner’s expectations.
Economic Benefits:
-
Zero electricity costs: Fully solar-powered operation saves over 5 million THB annually.
-
Low maintenance costs: Automatic fault alerts (FAS system) enable real-time monitoring. Combined with a 3-year warranty, maintenance expenses are reduced to one-third of traditional systems.
