How to Choose the Right Solar Street Light for Your Project
1. Determine the Installation Height
Installation height directly affects lighting performance.
General recommendations:
- 3–4 m: Garden paths
- 5–6 m: Residential roads
- 6–8 m: Urban streets
- 8–12 m: Main roads and highways
2. Consider Road Width
A wider road requires greater illumination and a larger beam angle.
Choosing the correct power and optical distribution helps ensure uniform lighting while avoiding wasted energy.
3. Select the Right Battery Capacity
Battery capacity determines how long the light can operate after sunset.
Projects in regions with frequent cloudy or rainy weather should use larger battery capacities to ensure continuous operation.
4. Choose the Appropriate Solar Panel
Solar panels should generate enough energy during the day to fully charge the battery.
Factors affecting panel selection include:
- Local sunshine hours
- Seasonal weather
- Daily lighting duration
- LED power consumption
5. Lighting Time Requirements
Typical operating modes include:
- Dusk to Dawn
- 6 Hours Full Brightness
- Smart Dimming
- Motion Sensor Mode
Selecting the appropriate mode improves energy efficiency and battery life.
6. Environmental Conditions
Consider:
- Temperature
- Rainfall
- Wind resistance
- Dust protection
- Corrosion resistance
For coastal environments, corrosion-resistant materials are recommended.
7. Choose a Reliable Manufacturer
A professional manufacturer should provide:
- Product certifications
- Engineering support
- OEM & ODM services
- Technical documentation
- Warranty
- After-sales service
