- Efficiency: Monocrystalline panels have an efficiency of 15-20%, while polycrystalline panels range from 13-16% (Source: SolarReviews).
- Size: Varies based on the power requirement, commonly between 50W to 300W.
Battery
- Type: Lithium-ion or lead-acid batteries are commonly used.
- Capacity: Ranges from 10Ah to 200Ah, depending on the system's energy storage needs.
- Lifespan: Lithium-ion batteries last up to 5-7 years, while lead-acid batteries last 2-3 years (Source: EnergySage).
LED Light
- Lumen Output: Typically ranges from 2,000 to 10,000 lumens.
- Color Temperature: Options include 3000K (warm white), 4000K (neutral white), and 5000K (cool white).
- Lifespan: LED lights can last up to 50,000 hours (Source: LEDVANCE).
Controller
- Type: PWM (Pulse Width Modulation) or MPPT (Maximum Power Point Tracking).
- Function: Manages the charging and discharging of the battery, ensuring optimal performance.
- Efficiency: MPPT controllers are more efficient, with efficiencies up to 98% compared to 80% for PWM controllers (Source: SolarEdge).
Pole and Mounting
- Material: Galvanized steel or aluminum.
- Height: Typically ranges from 4 to 12 meters.
- Design: Must be sturdy to withstand various weather conditions.
Performance Specifications
Light Output
- Illumination Area: Varies based on the height of the pole and the lumen output of the LED.
- Uniformity: A well-designed solar street light should provide uniform light distribution.
Autonomy
- Days of Autonomy: The system should be able to operate for 3-5 days without sunlight, ensuring reliability during cloudy weather.
Durability
- Ingress Protection (IP) Rating: Typically IP65 or higher to protect against dust and water.
- Operating Temperature: Should function effectively in temperatures ranging from -20°C to 60°C.
Installation Guidelines
Site Assessment
- Sunlight Exposure: Ensure the site receives at least 4-6 hours of direct sunlight daily.
- Obstructions: Check for any potential obstructions like trees or buildings that may cast shadows.
Mounting
- Pole Installation: Follow local regulations and ensure the pole is securely anchored.
- Angle Adjustment: Adjust the solar panel angle to maximize sunlight absorption, typically between 15° to 30° from horizontal.
Maintenance
- Regular Cleaning: Clean the solar panel and LED light to maintain efficiency.
- Battery Check: Monitor the battery's health and replace it when necessary.

FAQ
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.
