A Complete Sample and Specifications of Solar Street Light
In the dynamic solar lighting industry, understanding the detailed specifications and components of solar street lights is essential for professionals. This article offers a clear, concise overview of solar street light samples and specifications to aid in decision-making and implementation.
Key Components of Solar Street Lights
Solar street lights are composed of several integral parts that work together to provide efficient lighting. Below is a breakdown of these components:
- Solar Panel:
- Converts sunlight into electricity.
- Typically made of polycrystalline or monocrystalline silicon.
- Efficiency ranges from 15% to 20% (Source: Solar Energy Industries Association).
- Battery:
- Stores energy generated by the solar panel.
- Commonly uses lithium-ion or lead-acid batteries.
- Capacity varies based on the light's power requirements and autonomy needs.
- LED Light:
- Provides illumination using energy-efficient LED technology.
- Lumen output typically ranges from 2,000 to 10,000 lumens depending on the model.
- Lifespan of 50,000 to 100,000 hours (Source: LED Lighting Facts).
- Controller:
- Manages the charging and discharging of the battery.
- Includes features like overcharge protection and low voltage disconnect.
- Often integrated with dusk-to-dawn sensors for automatic operation.
- Pole and Mounting:
- Supports the solar panel, battery, and LED light.
- Material can be steel, aluminum, or concrete.
- Height typically ranges from 4 to 12 meters.
Performance Specifications
Understanding the performance metrics of solar street lights is crucial for ensuring they meet project requirements. Here are key specifications to consider:
- Lumen Output:
- Determines the brightness of the light.
- A typical solar street light might offer 5,000 to 7,000 lumens for residential areas and up to 10,000 lumens for highways (Source: Illuminating Engineering Society).
- Battery Capacity:
- Affects the autonomy of the light during non-sunny periods.
- A common specification is a 12V, 100Ah battery, providing 3-5 days of autonomy.
- Solar Panel Wattage:
- Influences the amount of energy harvested daily.
- A 100W to 300W panel is common, depending on the light's power needs.
- Operating Temperature:
- Ensures functionality in various climates.
- Typically ranges from -20°C to 60°C.
- IP Rating:
- Indicates the level of protection against dust and water.
- A rating of IP65 or higher is recommended for outdoor use (Source: International Electrotechnical Commission).
Industry Standards and Certifications
Adhering to industry standards and obtaining relevant certifications is vital for ensuring the quality and reliability of solar street lights. Key standards include:
- IEC 62257:
- International standard for off-grid renewable energy products.
- Ensures safety, performance, and durability.
- UL Certification:
- Underwriters Laboratories certification for safety and performance.
- Particularly important for products used in the United States.
- CE Marking:
- Indicates conformity with health, safety, and environmental protection standards for products sold within the European Economic Area.
