A Complete Sample and Specifications of Solar Street Light
In the solar lighting industry, understanding the components and specifications of solar street lights is crucial for professionals looking to implement efficient and reliable lighting solutions. This article provides a comprehensive overview of a complete sample and detailed specifications of solar street lights, addressing common pain points such as performance, durability, and installation requirements.
Key Components of a Solar Street Light
- Solar Panel: Converts sunlight into electricity. Typically, monocrystalline or polycrystalline panels are used, with efficiencies ranging from 15% to 20% (Source: Solar Energy Industries Association).
- Battery: Stores energy for use during nighttime. Commonly used batteries include lithium-ion and lead-acid, with capacities ranging from 10Ah to 200Ah depending on the system size.
- LED Light: Provides illumination. LED lights are preferred for their energy efficiency and long lifespan, typically offering 50,000 to 100,000 hours of operation (Source: LEDinside).
- Controller: Manages the charging and discharging of the battery. Modern controllers include features such as overcharge protection and dusk-to-dawn operation.
- Pole and Mounting Hardware: Supports the solar panel and light fixture. Materials like galvanized steel or aluminum are commonly used for durability and corrosion resistance.
Specifications of a Sample Solar Street Light
- Solar Panel: 120W monocrystalline, 19% efficiency, dimensions: 1100mm x 670mm x 30mm.
- Battery: 100Ah lithium-ion, 12V, expected lifespan of 5-7 years.
- LED Light: 50W, 5000 lumens, color temperature: 5000K, beam angle: 120°.
- Controller: MPPT (Maximum Power Point Tracking) type, 10A, with overcharge and deep discharge protection.
- Pole: 6 meters height, galvanized steel, with a mounting bracket for the solar panel and light fixture.
Performance Metrics
- Lumen Output: Typically ranges from 3000 to 10,000 lumens, depending on the LED wattage and efficiency.
- Autonomy: The number of days the light can operate without sunlight, usually between 2 to 5 days (Source: Solar Lighting International).
- Operating Temperature: Should function effectively in a range of -20°C to 60°C, ensuring reliability in various climates.
Installation Guidelines
- Site Assessment: Evaluate the location for optimal sunlight exposure, considering factors like shading and orientation.
- Mounting: Ensure the pole is securely anchored, and the solar panel is angled to maximize solar intake, typically between 15° and 45° depending on latitude.
- Wiring: Use appropriate gauge wiring to minimize energy loss, and ensure all connections are weatherproof.
Maintenance and Durability
- Cleaning: Regular cleaning of the solar panel to remove dust and debris is recommended to maintain efficiency.
- Battery Replacement: Plan for battery replacement every 5-7 years, depending on usage and environmental conditions.
- Durability: Expect a lifespan of 10-20 years for the overall system, with proper maintenance and component replacements as needed (Source: U.S. Department of Energy).
By understanding these components, specifications, and guidelines, professionals in the solar lighting industry can better select and implement solar street light solutions that meet their project needs and performance expectations.

Commercial and Industrial Parks
Do solar lights work well in large parking areas?
Yes, our solar lights provide uniform illumination ideal for expansive parking areas, ensuring safety and visibility.
Battery Performance and Testing
What is the standard charge retention test?
After the battery is discharged to 1.0V at 0.2C, it is charged at 0.1C for 16 hours, stored at a temperature of 20℃±5℃ and a humidity of 65%±20% for 28 days, and then discharged to 1.0V at 0.2C. NiMH batteries should last longer than 3 hours.
The national standard stipulates that the standard charge retention test of lithium batteries is: (IEC has no relevant standards) The battery is discharged to 3.0/unit at 0.2C, and then charged to 4.2V at 1C constant current and constant voltage, with a cut-off current of 10mA, at a temperature of 20 ℃±5℃, after 28 days of storage, discharge at 0.2C to 2.75V, calculate the discharge capacity, and compare it with the battery's nominal capacity, it should not be less than 85% of the initial capacity.
