- DAT Solar sponsored Sokoyo lights for the lighting project at Dinh Cau, Phu Quoc.
With the aim of “Illuminating every road with solar energy lights” to allow people to experience and understand the benefits of smart lighting solutions, DAT Solar sponsored 27 sets of Sokoyo lights from the LUMO 60W series. This initiative was in collaboration with partner Solar Phu Gia to implement the project, illuminating Dinh Cau and Bach Dang Park—two famous tourist spots on the pearl island of Phu Quoc.
- Illuminating the road to Phu Quoc Airport with Sokoyo solar lights
In August 2021, Truc Ngoc Engineering Construction Technical Energy Company Limited, a partner of DAT Solar, successfully implemented a lighting project for a 2.2km belt road at Phu Quoc Airport using Sokoyo solar energy systems. The project received praise for its excellent lighting performance, meeting expectations and project goals. It demonstrated the vision of the investor, bringing significant economic and environmental values.
3. Advantages of Sokoyo solar street lights
Sokoyo Solar Light’s solar street lights are among the products manufactured using modern technology, highly applicable in illuminating urban traffic, industrial zones, villas, hotels, households, etc. These lights are currently the most popular choice, offering several advantages:
- High economic efficiency: Optimizes costs by absorbing solar energy for lighting, saving installation and construction costs.
- High durability and long lifespan: LED chips have an average lifespan of 12-15 years, solar panels have a durability of over 25 years, and Lithium LiFePO4 storage batteries have a lifespan of 5-8 years. Additionally, the light casing is made of solid material, electrostatically painted, corrosion-resistant, and impact-resistant, performing well in high-temperature environments, prolonged rain, and dusty conditions.
- 100% solar energy use, no electricity consumption: Unlike conventional lights that require grid electricity to operate, solar street lights operate entirely automatically by absorbing sunlight, converting it into electrical energy, and storing it for nighttime illumination. Therefore, solar street lights operate independently of the grid, ensuring normal brightness without electricity costs.
- Safety and cost savings: Solar street lights do not require grid connection, saving costs associated with wiring and excavation. They only need pole installation, making them suitable for challenging terrains, remote areas, and islands without grid electricity. Moreover, solar lights use low DC voltage, almost without impact, making them safe for installation and maintenance.
- Excellent lighting capability: Sokoyo Solar Lights have LED chip efficiency ≥170lm/W, providing high brightness. Power ranges from 10-150W, suitable for lighting projects of various scales, meeting all usage needs.
- Motion detection sensor: Smart controllers enable the light to turn on automatically at night and off during daylight. Brightness, operation monitoring, charge/discharge levels can be adjusted to extend the lifespan of storage batteries. New products also incorporate Microwave sensor technology, gradually replacing the old PIR sensor technology, enabling faster motion detection.
4. Disadvantages of Solar street lights
Alongside the advantages, solar street lights have some drawbacks that need improvement:
- High initial investment: Although the upfront cost is high, in the long run, users can save on monthly electricity costs, thanks to solar energy application.
- Risk of theft: If lights are placed in poorly monitored locations, there is a risk of theft.
- Dependent on light positioning: Depending on the type of solar light used, there are different requirements for light placement to avoid shading, ensuring effective light absorption.
- Weather dependence: In prolonged rainy or cloudy weather, solar lights may not function optimally as they cannot absorb solar energy effectively.
5. Structure of solar street lights
Depending on different models, solar street lights are composed of various parts. In general, they consist of key components such as LED lights, solar panels, storage batteries, intelligent controllers, etc.
- LED lights: The light casing is typically made of explosion-proof aluminum alloy to protect the LED chips inside. This design allows the light to adapt to unusual weather conditions, as seen in Vietnam.
- Solar panels: One of the critical and indispensable parts of solar street lights, these panels absorb sunlight to convert it into electrical energy to power the lights. The lights usually use mono or poly solar panels with a high lifespan, typically over 25 years.
- Lithium storage battery: With high durability and a long lifespan, these batteries store electrical energy converted from solar panels until it is fully charged on sunny days. Lithium LiFePO4 batteries, commonly used, have storage capacities 10-14 times higher than the light’s power, ensuring 2-3 days of illumination in case of prolonged rain.
- Other components: Light pole, control system, connecting cables, light sensor, etc.
6. Working principle of solar street lights
Although there are various types of solar lights on the market, they share a similar structure, and thus, solar LED street lights have the same working principle. These lights operate entirely automatically without specific human intervention as follows:
- Daytime: When it’s daylight, solar street lights automatically turn off. During this time, solar panels absorb energy and charge the storage battery. When the battery is fully charged, the energy control system automatically stops charging.
- Nighttime: When it’s dark, the energy control system automatically transfers energy from the battery to power the lights. At this point, the lights illuminate until the end of the night. The next morning, the lighting system automatically turns off, and the solar panels continue their work of charging energy.
This automatic operating mechanism, coupled with waterproof and weather-resistant features, allows these lights to be installed in various areas with significant energy savings compared to conventional lights.
7. Calculations for choosing suitable solar street lights
In the design process, choosing suitable products for solar street lighting projects is crucial for optimal efficiency and cost-effectiveness. Therefore, accurate calculations of solar panel power, battery capacity, and the illuminated area are necessary.
To ensure the optimal installation of solar street lights, consider important factors such as:
- Calculating light pole height: To calculate the height of the light pole, information about the light’s power or the road’s width and the installation system type for each project is required.
- Illuminated area.
- Battery storage capacity calculation.
- Solar panel power calculation.
8. Quality standards for choosing solar street lights
Depending on the usage purpose and installation location, different standards apply when selecting high-quality solar street lights. Before deciding to purchase solar lights, consider choosing products with good quality, modern technology, and compliance with technical specifications, safety standards, and investment efficiency.
Quality standards for choosing solar street lights include:
- Clear, detailed, and reliable technical specifications.
- Application of modern technology and smart control.
- Integration with IoT monitoring systems.
- Clear origin, with complete CO and CQ documentation.
- Compliance with international standards such as CE, IEC, RoHS.
- Warranty and replacement policies within Vietnam.
9. DAT Solar wishes to collaborate with lighting system installation units
